                     PEDIGREE OF CYNDDELW GAM OF YSTRAD ALUN
                                         By Darrell Wolcott
 
       This pedigree, which extends down to about the year 1400, uses the same sources cited by Peter Bartrum in his "Welsh Genealogies - AD300-1400" but assembles the data in a chronologically consistent manner, leaving no time gaps nor any of the anachronisms found in his charts.  It includes families we believe belong here which were not connected by Bartrum.  Names are spelled according to our preferred orthography and all birthdate estimates have been rounded to the nearest year ending with 0 or 5.
 
        For every child and every marriage connection claimed, our sources for the data follow the narrative in red type.  In many cases, there are more sources than shown, but if one source extends the person's ancestry back more generations than all others, only that source is cited.  In the majority of cases, no single source cites more than 3 or 4 generations so it is necessary to "connect" the ancestry by reference to distinctly separate sources, and this joining of sources may occur more than once to reach back to a well-known ancestor.  Each such connection introduces the opportunity for error due to the abundance of same-named men found within the body of Welsh pedigree manuscripts.  Our constructions often differ from those presented by Bartrum, but all maintain a sound chronological timeline.  Where particular problems exist, they are fully discussed and the reasons for choosing our construction are given.  There can be no certainty that our choices, or anyone else's, are absolutely correct.

Index of names

GENERATION 1:
 
1.  Cynddelw Gam ap Elgudy, born c. 880
     As a young man, Cynddelw accompanied his father in the engagement which cleared Danish squatters from Tegeingl and the Clwyd valley.  His uncorrected vision required him to squint when viewing anything from close up and earned him the nickname "Gam".  Born in mid-Powys near Deuddwr, he settled in Ystrad Alun on lands granted to his father by Selyf ap Brochwel, king of Powys, around the year 900/905.  His wife is unknown, but he had a son:
 
           2.  Cynwrig ap Cynddelw Gam ap Elgudy
 
ABT 1c and HLG 5a cite "Cynddelw Gam ap Elgudy ap Gwrysnadd" as father of Cynwrig
 
GENERATION 2:
 
2.  Cynwrig ap Cynddelw Gam ap Elgudy, born c. 915.
     He inheirited his father's lands, which included Ystrad Alun, Dyffryn Clwyd and a sizaeable manor near Rhuddlan in Tegeingl.  His wife is unknown, but he had 3 sons:
 
           3.  Gweirydd ap Cynwrig ap Cynddelw Gam
           4.  Marchen ap Cynwrig ap Cynddelw Gam
           5.  Pyll ap Cynwrig ap Cynddelw Gam
 
Pen. 131, 286 cites "Gweirydd ap Cynddelw Gam" while HLG 5a cites "Cynwrig ap Cynddelw Gam".  Both the chronology and Peter Bartrum suggest the correct form is "Gweirydd ap Cynwrig ap Cynddelw Gam"
 
ABT 1c cites "Marchen ap Cynwrig ap Cynddelw Gam"
 
ABT 6i cites "Pyll ap Cynwrig ap Cynddelw Gam"
 
GENERATION 3:
 
3.  Gweirydd ap Cynwrig ap Cynddelw Gam, born c. 945
     He received Ystrad Alun and a part of the Tegeingl manor, electing to reside at the latter.  His wife is unknown, but he had a son:
 
           6.  Coel ap Gweirydd ap Cynwrig
 
Pen. 131, 286 cites "Coel ap Gweirydd ap Cynddelw Gam" which lacks one generation to be chronologically satisfactory.  Bartrum would make Gweirydd the son of Cynwrig ap Cynddelw Gam and we concur
 
4.  Marchen ap Cynwrig ap Cynddelw Gam, born c. 950
     He received much of Dyffryn Clwyd as his share of his father's lands.  His wife is unknown, but he had a son:
 
            7.  Rhys ap Marchen ap Cynwrig
 
ABT 1c cites "Marchen ap Cynwrig ap Cynddelw Gam" as father of Rhys
 
5.  Pyll ap Cynwrig ap Cynddelw Gam, born c. 950
     He received lands in the north of Dyffryn Clwyd and the remainder of the manor near Rhuddlan.  His wife is unknown, but he had a son:
 
            8.  Gwair ap Pyll ap Cynwrig
 
ABT 6i cites "Pyll ap Cynwrig ap Cynddelw Gam " as father of Gwair
 
GENERATION 4:
 
6.  Coel ap Gweirydd ap Cynwrig, born c. 975
     He inheirited Ystrad Alun and the manor called Bryn near Rhuddlan.  After serving king Llewelyn ap Seisyllt (c. 980), he married a sister (c. 990) of that Llewelyn and had 2 sons:
 
            9.  Llewelyn ap Coel ap Gweirydd
          10.  Ithel ap Coel ap Gweirydd
 
Pen. 131, 286 and Pen. 128, 186 cite "Coel ap Gweirydd" as father of Llewelyn Aurdorchog
 
The marriage of Coel to a sister of King Llewelyn ap Seisyllt is our suggestion; since Coel's son served as penteulu for Gruffudd ap Llewelyn ap Seisyllt and since that position was reserved by law to a near relative of the king, we posit the men were first cousins
 
No source gives the ancestry of this Ithel; we suggest he was a younger brother of Llewelyn Aurdorchog. 
 
7.  Rhys ap Marchen ap Cynwrig, born c. 985
     His wife is unknown, but later in life he had a single daughter:
 
              Gwenllian ferch Rhys ap Marchen, born c. 1025.  She inheirited his lands in Dyffryn Clwyd and married Morien (c. 1015) ap Morganeau (c. 985) ap Gwerystan (c. 950), a first cousin of Rhiwallon and Bleddyn ap Cynfyn ap Gwerystan.  Their son, Eunydd (c. 1045), served in Bleddyn's warband c. 1070-75
 
ABT 1c cites "Gwenllian ferch Rhys ap Marchen ap Cynwrig" as mother of Eunydd
 
Dwnn ii, 83 & 355 cite "Gwenllian ferch Rhys ap Marchen" married "Morien ap Morgeneu ap Gwerystan ap Gwaethfoed" and was mother to Eunydd
 
8.  Gwair ap Pyll ap Cynwrig, born c. 985
     His wife is unknown, but he had a daughter:
 
              Afandreg ferch Gwair ap Pyll, born c. 1020.  She was about 13 when Iago (c. 1005) ap Idwal (c. 975) ap Elisedd (c. 945) of Gwynedd invaded Powys and took Rhuddlan from its interim king, Cynfyn ap Gwerystan.  While the more senior Powys noblemen went into the mountains of Ial to avoid capture and to protect their young king-to-be, Gruffudd ap Llewelyn, Gwair struck a truce with Iago and gave Afandreg to be his wife.  She was to be widowed 6 years later when Gruffudd emerged as king of Powys and killed Iago.  She and her young son, Cynan (c. 1035), resided at Iago's manor of Aberffraw in Anglesey.
 
ABT 6i cites "Afandreg ferch Gwair ap Pyll ap Cynwrig" as the mother of Cynan ap Iago, thus the wife of Iago
 
GENERATION 5:
 
9.  Llewelyn ap Coel ap Gweirydd, born c. 1005
     He was sent at age 14 to serve at the court of King Llewelyn ap Seisyllt, and remained at court when that man died in 1023.  Cynfyn ap Gwerystan married the king's widow to become the step-father of young Gruffudd.  Installed as the interim king of Powys, Cynfyn brought to court with him three young daughters by a first wife.  About 1033, Llewelyn married one of those daughters, Efa (c. 1020).  When Gruffudd ap Llewelyn became old enough to stake a kingship claim, he chose Llewelyn ap Coel as his senior official...the penteulu or leader of his warband.  It was during that service he donned the gold torc which was the ancient symbol of a Celtic battle leader, and became better known as Llewelyn Aurdorchog.  As a reward for his services, he was granted the commote of Ial located just south of Ystrad Alun. He and Efa had 4 sons:
 
           11.  Llewelyn Fychan ap Llewelyn Aurdorchog
           12.  Ithel Hen ap Llewelyn Aurdorchog
           13.  Ednowain ap Llewelyn Aurdorchog
                 Rhys ap Llewelyn Aurdorchog, born c. 1045.  He had a single daughter, Gwenllian born c. 1080, who married Ithel (c. 1075) ap Eunydd of Dyffryn Clwyd (c. 1045)
 
Cae Cyriog Ms and B.M. Add. 9864 cite "Llewelyn Aurdorchog ap Coel ap Gweirydd" married "Efa ferch Cynfyn ap Gwerystan".  Harl. 1972, 135 and Harl. 1977, 226 incorrectly emended that to "Efa ferch Bleddyn ap Cynfyn" by mis-dating Llewelyn Aurdorchog one generation forward.
 
Dwnn i, 308 cites "Llewelyn Aurdorchog" as father to Llewelyn Fychan
 
No sources cite the ancestry of Ithel Hen; Dwnn ii, 300, note 3 calls him "of the tribe of Ial".  Chronologically, he fits as a son of Llewelyn Aurdorchog; most pedigrees call Ithel Felyn such a son, but only our construction fits both men
 
Dwnn ii, 243 cites "Llewelyn Aurdorchog" as father to Owain Aurdorchog but Cae Cyriog Ms and others call this son Ednowain Aurdorchog.
 
Pen. 287, 181 cites "Gwenllian ferch Rhys ap Llewelyn Aurdorchog" married "Ithel ap Eunydd'
 
All other children attributed to Llewelyn Aurdorchog by various pedigrees actually belong to other (later) men in the family named Llewelyn; these include Ithel Felyn, Iorwerth, Idris, Gwgan and Dolffyn, plus a lady named Nest
 
10.  Ithel ap Coel ap Gweirydd, born c. 1007
       He also served at the courts of Llewelyn ap Seisyllt and Cynfyn ap Gwerystan, and about 1035 married another of the daughters of Cynfyn named Nest (c. 1022).  Like his older brother, he had grown to manhood as both first-cousin and foster brother of Gruffudd ap Llewelyn.  When the latter became king in 1039, he named Ithel as his pencynydd or chief huntsman in charge of the care and training of the hounds. A Welsh king of that era had only two things he was passionate about: fighting and hunting.  Thus the two sons of Coel became Gruffudd's top officials in each of those pursuits.  Ithel and Nest resided at the patrimonial manor of Bryn near the castle at Rhuddlan.  For his services to the king, he was granted lands in Pennant Melangell in the commote of Mochnant.  He and Nest had a son:
 
           14.  Ednowain ap Ithel ap Coel
 
The ancestry of Ithel is nowhere given; see the paper "Ithel of Bryn in Powys" elsewhere on this site for the suggestion he was a younger brother of Llewelyn Aurdorchog
 
HLG 2c cites "The mother of Ednowain ap Ithel of Bryn in Powys and of Pennant Melangell was Nest ferch Cynfyn ap Gwerystan"
 
GENERATION 6:
 
11.  Llewelyn Fychan ap Llewelyn Aurdorchog, born c. 1035
      Succeeding to the Lordship of Ial and Ystrad Alun after the death of his father, he cemented his friendship with the clan of Elystan Glodrydd in Fferlys which lay south of Powys by marrying Annes (c. 1050), daughter of Cadwgan (c. 1020) ap Elystan (c. 985). His lands were a portion of "north Wales" for which the Norman Robert of Rhuddlan paid 40 pounds annually to rule.  This Robert did not personally involve himself in every-day affairs in Wales, but approved sub-rulers who rendered to him those rents and fees normally paid to a Welsh king.  Llewelyn Fychan paid 40 shillings rent in 1086 for Ial when its population was said to be 33 men and 2 priests.  He and Anne had 4 sons and 2 daughters:
 
            15.  Ithel Felyn ap Llewelyn Fychan ap Llewelyn Aurdorchog
            16.  Idris ap Llewelyn Fychan ap Llewelyn Aurdorchog
            17.  Iorwerth ap Llewelyn Fychan ap Llewelyn Aurdorchog
            18.  Rhys Goch ap Llewelyn Fychan ap Llewelyn Aurdorchog
                  Nest ferch Llewelyn Fychan, born c. 1065.  She married Uchdryd (c. 1055) ap Edwin of Tegeingl (c. 1020), leader of the warband of Cadwgan ap Bleddyn ap Cynfyn
                  Alison ferch Llewelyn Fychan, born c. 1070.  She married Maredudd (c. 1055) ap Cynan (c. 1014) ap Idwal (c. 975), a priest at the household of Cadwgan ap Bleddyn and the younger brother of the Gruffudd ap Cynan who tried and failed to claim the kingship of Gwynedd in 1075 and 1081.
 
Montgomeryshire Collections vol vii, pp 54 cites "Llewelyn Fychan ap Llewelyn Aurdorchog married Agnes (Annes) ferch Cadwgan ap Elystan Glodrydd"
 
HLG 5b cites "Ithel Felyn of Ial ap Llewelyn Aurdorchog" which omits Llewelyn Fychan, but that source also omits both the father and grandfather of Llewelyn Aurdorchog
 
Pen. 131, 286; Pen. 128, 75b & 186b; and Pen. 139(1), 82 cite "Idris ap Llewelyn Aurdorchog" but the family descended from Idris clearly dates him to the generation of grandchildren of Llewelyn Aurdorchog. 
 
Pen. 127, 63; Pen. 128, 272a; Pen. 176, 84; and Pen 139(1), 123 cite "Iorwerth ap Llewelyn Aurdorchog" but he also occurs 2 generations after Llewelyn Aurdorchog
 
Dwnn i, 308 cites "Rhys Goch ap Llewelyn Fychan ap Llewelyn Aurdorchog"
 
Pen. 287, 291 cites "Nest ferch Llewelyn Aurdorchog married Uchdryd ap Edwin ap Gronwy"; Uchdryd was born c. 1050/55 making his wife actually the daughter of Llewelyn Fychan.
 
Cedwyn Ms reproduced in Montgomeryshire Collections, vol x, pp 21 cites "Alson ferch Llewelyn Fychan ap Llewelyn Aurdorchog married Maredudd ap Cynan"
 
By moving the birth of Llewelyn Aurdorchog forward one generation to call him the father of Ithel Felyn, several of his grandchildren were cast as his children in most medieval pedigrees. 
 
12.  Ithel Hen ap Llewelyn Aurdorchog, born c. 1036
      His wife is unknown, but he had a son:
 
              19.  Llewelyn ap Ithel Hen ap Llewelyn Aurdorchog
 
Dwnn ii, 300 note 3 cites "Ithel Hen of Ial" as the father of Llewelyn
 
13.  Ednowain ap Llewelyn Aurdorchog, born c. 1040
      He served as penteulu for Bleddyn ap Cynfyn, who was his mother's half-brother.  During that service as leader of King Bleddyn's warband, he earned the "Aurdorchog" nickname his father had borne.  His wife is unknown, but he had 2 sons:
 
             20.  Dafydd Ysgyd Aur ap Ednowain Aurdorchog
             21.  Gwrydyr ap Ednowain Aurdorchog
 
Dwnn ii, 243 cites "Owain Aurdorchog" as father of Dafydd Ysgyd Aur
 
HLG 5a cites "Ednowain ap Llewelyn Aurdorchog" as father of Gwrydyr
 
14.  Ednowain ap Ithel ap Coel, born c. 1040
      He married Generys (c. 1055) ferch Rhys Sais (c. 1025) ap Ednyfed (c. 995) of Maelor and had a son:
 
             22.  Gwrgeneu ap Ednowain ap Ithel
 
HLG 2c & d cites "the mother of Gwrgeneu ap Ednowain ap Ithel was Generys ferch Rhys Sais of Maelor", while HLG 12a extends her ancestry to "Rhys Sais of Maelor ap Ednyfed ap Llywarch Gam ap Llyddocca ap Tudor Trevor"
 
GENERATION 7:
 
15.  Ithel Felyn ap Llewelyn Fychan ap Llewelyn Aurdorchog, born c. 1065.  He succeeded his father as Lord of Ial and Ystrad Alun about 1094 and married Lleuci (c. 1080) ferch Hwfa (c. 1045) ap Brochwel (c. 1010) ap Bledrus (c. 980) of Anglesey.  While one late manuscript cites Marged and Susanna as his daughters, no marriage for either is mentioned.  But Ithel Felyn did have a son:
 
            23.  Hwfa ap Ithel Felyn ap Llewelyn Fychan
 
Harl. 1972, 137v and Harl. 1977, 38v & 124 cite "Ithel Felyn ap Llewelyn Aurdorchog" (omitting Llewelyn Fychan) married "Lleuci ferch Hwfa ap Brochwel ap Bledrus y Moelwyn". 
 
Pen. 287, 497 cites Marged and Susanna as unmarried daughters of Ithel Felyn, ladies unknown to earlier manuscripts
 
16.  Idris ap Llewelyn Fychan ap Llewelyn Aurdorchog, born c. 1070.
      His wife is unknown, but he had a son:
 
            24.  Ithel ap Idris ap Llewelyn Fychan
 
Pen. 131, 186 and Pen. 128, 75b & 186b cite "Idris ap Llewelyn Aurdorchog (omitting Llewelyn Fychan) as father of Ithel
 
17.  Iorwerth ap Llewelyn Fychan ap Llewelyn Aurdorchog, born c. 1070
      His wife is unknown, but he had a son:
 
            25.  Llewelyn ap Iorwerth ap Llewelyn Fychan
 
Pen. 127, 63 and Pen. 128, 272a cite "Iorwerth ap Llewelyn Aurdorchog" but the subsequent families place Iorwerth 2 generations after Llewelyn Aurdorchog
 
18.  Rhys Goch ap Llewelyn Fychan ap Llewelyn Aurdorchog, born c. 1075
      He married Lleuci (c. 1090) ferch Llewelyn (c. 1060) ap Meilyr Gryg (c. 1025) of Gregynog in Cydewain and settled on his wife's manor in southern Powys.  It was not unusual for younger siblings who held patrimonial lands now ruled by an older brother to seek residence elsewhere.  Rhys Goch leased out his lands in Ystrad Alun and Ial to move south.  He and Lleuci had a son:
 
            26.  Einion ap Rhys Goch ap Llewelyn Fychan
 
Montgomeryshire Collections, vol vii, pp 55 cites "Rhys Goch ap Llewelyn Fychan ap Llewelyn Aurdorchog" married "Lleuci ferch Llewelyn ap Meilyr Gryg and was the father of Einion"
 
19.  Llewelyn ap Ithel Hen ap Llewelyn Aurdorchog, born c. 1065
      His wife is unknown, but he had a son:
 
            27.  Madog ap Llewelyn ap Ithel Hen
 
Dwnn ii, 300 note 3 cites "Llewelyn ap Ithel Hen" as father of Madog
 
20.  Dafydd Ysgyd Aur ap Ednowain Aurdorchog, born c. 1065
      His footwear was decorated with gold braid and he was known as Dafydd with the gold boots.  His wife is unknown, but he had a son:
 
            28.  Idnerth ap Dafydd Ysgyd Aur ap Ednowain Aurdorchog
 
Dwnn ii, 243 cites "Dafydd Ysgyd Aur ap Owain Aurdorchog" as father of Idnerth
 
21.  Gwrydyr ap Ednowain Aurdorchog, born c. 1070
       His wife is unknown, but he had a son:
 
            29.  Bledrys ap Gwrydyr ap Ednowain Aurdorchog
 
HLG 5a cites "Gwrydyr ap Ednowain ap Llewelyn Aurdorchog" as father of Bledrys
 
22.  Gwrgeneu ap Ednowain ap Ithel, born c. 1080
       He married Gwledyr (c. 1100) ferch Seisyllt (c. 1070) ap Gwrgi (c. 1040) of castell Caereinion and only had 2 daughters:
 
                 Arianrodd ferch Gwrgeneu ap Ednowain, born c. 1110.  She married Collwyn (c. 1095) ap Moreiddig (c. 1060) ap Rhys (c. 1030) of Penllyn and was the grandmother of Rhiryd Flaidd ap Gwrgeneu ap Collwyn, Lord of Penllyn
                 Genelles ferch Gwrgeneu ap Ednowain, born c. 1115.  She married the noted bard Gwalchmei (c. 1000) ap Meilyr (c. 970).
 
HLG 2e cites "Gwledyr ferch Seisyllt ap Gwrgi" as mother of Genelles ferch Gwrgeneu ap Ednowain" thus wife of Gwrgeneu
 
HLG 2b cites "Genelles ferch Gwrgeneu ap Ednowain ap Ithel of Bryn" as the mother of Einion ap Gwalchmei ap Meilyr, thus the wife of Gwalchmei
 
Pen. 139(1), 39 cites "the mother of Gwrgeneu ap Collwyn was a daughter of Gwrgeneu ap Ednowain of Bryn"; Harl. 1977, 245 names the lady "Aneiwrodd" which is probably "Arianrodd"
 
GENERATION 8:
 
23.  Hwfa ap Ithel Felyn ap Llewelyn Fychan, born c. 1095
      He succeeded his father as Lord of Ial and Ystrad Alun and married Yslani (c. 1110) ferch Iago (c. 1075) ap Gruffudd (c.1041) ap Cynan (c. 1015) ap Idwal (c. 975).  They had 4 sons:
 
             30.  Ithel y Gwion ap Hwfa ap Ithel Felyn
             31.  Caswallon ap Hwfa ap Ithel Felyn
             32.  Hywel Foel ap Hwfa ap Ithel Felyn
                   Gronwy ap Hwfa ap Ithel Felyn, born c. 1130.  He had a son:      
                         Iorwerth ap Gronwy ap Hwfa, born c. 1160, whose daughter: 
                                Tangwystl ferch Iorwerth ap Gronwy, born c. 1195, married Llewelyn ap Dolffyn ap Iorwerth.  See #71 below
 
HLG 5b cites "the wife of Hwfa ap Ithel Felyn was Yslani ferch Gruffudd ap Cynan" but ABT 5b (which also cites this marriage) adds that Yslani was the sister of Iago ap Gruffudd ap Cynan by a common mother.  But that Iago can be dated c. 1075 and almost certainly was the father, not sister, of Yslani. 
 
Pen. 127, 64 and Pen. 128, 272a cite "Tangwystl ferch Iorwerth Swdrgrin ap Gronwy ap Hwfa ap Ithel Felyn" married "Llewelyn ap Dolffyn ap Iorwerth"
 
24.  Ithel ap Idris ap Llewelyn Fychan, born c. 1105
      His wife is unknown, but he had a son:
            
               33.  Tudor ap Ithel ap Idris
 
Pen. 131, 286 and Pen. 128, 186b cite "Ithel ap Idris" as father of Tudor
 
25.  Llewelyn ap Iorwerth ap Llewelyn Fychan, born c. 1100
      A number of genealogists confuse this man with Llewelyn Aurdorchog, appending his children to that earlier man.  His wife is unknown, but he had 3 sons and a daughter:
 
               34.  Dolffyn ap Llewelyn ap Iorwerth
               35.  Iorwerth ap Llewelyn ap Iorwerth
               36.  Gwgan ap Llewelyn ap Iorwerth
                     Nest ferch Llewelyn ap Iorwerth, born c. 1135.  She married Llewelyn (c. 1130) ap Madog (c. 1095) ap Maredudd (c. 1065) ap Bleddyn (c. 1025) ap Cynfyn (c. 990)
 
Pen. 127, 63 & 129; Pen. 128, 272a; Harl. 1973, 26v; and Harl. 1977, 268 all mistake this Llewelyn for Llewelyn Aurdorchog.  Perhaps he also bore that nickname, but clearly dates nearly 100 years later than the first man of that name. 
 
Harl. 1977, 268 cites "Nest ferch Llewelyn" married "Llewelyn ap Madog" but corruptly misidentifies both spouses.  Bartrum's attempt to chart Llewelyn ap Madog is absurdly anachronistic, making Madog 3 generations older than his "father"
 
26.  Einion ap Rhys Goch ap Llewelyn Fychan, born c. 1105
      His wife is cited as Sian ferch Einion (c. 1110) ap Seisyllt (c. 1075) of Mathafarn, but such a lady would be a full generation too young for such a marriage.  Perhaps she was a sister of Einion ap Seisyllt whose relationship was altered to daughter by those medieval genealogists who dated Llewelyn Aurdorchog one generation later and claimed he was the father of Ithel Felyn.  Raised in southern Powys where his father had moved, Einion had a son:
 
             37.  Iorwerth ap Einion ap Rhys Goch
 
Montgomeryshire Collections, vol vii, pp 55 cites "Einion ap Rhys Goch ap Llewelyn Fychan" married "Sian ferch Einion ap Seisyllt".  Either this marriage is fiction, or Sian was actually a sister of Einion ap Seisyllt
 
27.  Madog ap Llewelyn ap Ithel Hen, born c. 1095
      His wife is unknown, but he had a son:
 
             38.  Iorwerth ap Madog ap Llewelyn
 
Dwnn ii, 300 note 3 cites "Madog ap Llewelyn ap Ithel Hen" as father of Iorwerth
 
28.  Idnerth ap Dafydd Ysgyd Aur ap Ednowain Aurdorchog, born c. 1095
       His wife is unknown, but he had a son:
 
             39.  Bradwen ap Idnerth ap Dafydd Ysgyd Aur
 
Dwnn ii, 243 cites "Idnerth ap Dafydd Ysgyd Aur" as father of Bradwen. However, Dwnn ii, 284 cites the father of Bradwen as "Idnerth ap Edryd", a man born c. 1040 or 2 generations too early to be his father.  Pen. 234, 30 makes the father of Bradwen "Mael ap Bleydud ap Morud", a man born c. 1050.  We have opted for the only version of his ancestry which works chronologically.
 
29.  Bleddri ap Gwrydyr ap Ednowain Aurdorchog, born c. 1100
      His wife is unknown but he had a son:
 
              Cadwgan ap Bleddri ap Gwrydyr, born c. 1130.  He had 4 sons of whom nothing is known:
 
                     Rhys ap Cadwgan ap Bleddri, born c. 1160
                     Arthen ap Cadwgan ap Bleddri, born c. 1160
                     Meilyr ap Cadwgan ap Bleddri, born c. 1165
                     Tegwared ap Cadwgan ap Bleddri, born c. 1165
 
HLG 5a cites "Rhys and Arthen and Meilyr and Tegwared" as sons of "Cadwgan ap Bleddri ap Gwrydyr ap Ednowain ap Llewelyn Aurdorchog"
 

GENERATION 9:
 
30.  Ithel y Gwion ap Hwfa ap Ithel Felyn, born c. 1125
      Called simply "Y Gwion" in most pedigrees, we think the nickname was corrupted from "y wyrion" or "the grandson".  It was rare in that era for a child to be born during the life of his grandfather, but when such a child was given the same name as his grandfather, the nickname was added to distinguish between them...as well as to call attention to the rare feat of even having a living grandfather.  Since the grandfather of this man was Ithel Felyn, we suggest his birth name was Ithel the grandson.  He succeeded his father as Lord of Ial and Ystrad Alun but during his lifetime lost much of that land and his title to Gruffudd Maelor ap Madog ap Maredudd, king of north Powys.  He married Lleuci (c. 1125) ferch Maredudd (c. 1090) ap Cadwgan (c. 1055) ap Bleddyn (c. 1025); they had a 2 sons and a daughter:
 
             40.  Cadwgan Goch ap Ithel Y Gwion ap Hwfa
             41.  Cynddelw ap Ithel Y Gwion ap Hwfa
                    Nest ferch Ithel Y Gwion ap Hwfa, born c. 1160.  She married Radfarch (c. 1150) ap Alser (c. 1115) ap Gwrgi (c. 1080) ap Hedd (c. 1050) ap Alunog (c. 1020) descended from Tudwal Gloff ap Rhodri Mawr.
 
Pen. 129, 111; Pen. 127, 132 and Pen. 128, 148a cite "Y Gwion ap Hwfa ap Ithel Felyn" as the father of Cadwgan Goch
 
Pen. 287, 385 cites "Y Gwion ap Hwfa ap Ithel Felyn" married "Lleuci ferch Maredudd ap Cadwgan", while Pen. 129, 45 extends her ancestry to "Maredudd ap Cadwgan ap Bleddyn"
 
Dwnn ii, 278 cites "Cynddelw ap Ithel Felyn" but he was born c. 1155 or 3 generations after Ithel Felyn.  We think the Ithel who was father to Cynddelw was the one often called "Y Gwion" who does fit chronologically
 
Pen 276, 556 cites "Nest ferch Y Gwion ap Hwfa" married "Rhahawd Fach ap Alser ap Gwrgi" while Pen. 128, 258b calls him "Radfach ap Alser ap Gwrgi".  HLG 10b extends his ancestry as "Gwrgi ap Hedd ap Alunog"
 
31.  Caswallon ap Hwfa ap Ithel Felyn, born c. 1130
       His wife is unknown, but he had a 3 sons:
 
             42.  Iorwerth ap Caswallon ap Hwfa
             43.  Maredudd ap Caswallon ap Hwfa
             44.  Bleddyn ap Caswallon ap Hwfa
 
Pen. 131, 52; Pen. 129, 84; Pen. 127, 136; and Pen. 128, 213b cite "Caswallon ap Hwfa ap Ithel Felyn" as father of Iorwerth
 
Pen. 287, 504 cites "Caswallon ap Hwfa ap Ithel Felyn" as father of Bleddyn
 
Pen. 177, 166 and Pen. 134, 69 cite Maredudd as a son of Hwfa, but he occurs in the generation of grandsons of Hwfa.  We think he was a brother of Iorwerth and Bleddyn
 
32.  Hywel Foel ap Hwfa ap Ithel Felyn, born c. 1130
      His wife is unknown, but he had two sons:
 
             45.  Ieuaf ap Hywel Foel ap Hwfa
             46.  Einion ap Hywel Foel ap Hwfa
 
Harl. 2299 cites "Hywel Foel ap Hwfa ap Ithel Felyn" as father of Ieuaf.  Other sources call Ieuaf "Ieuan" and incorrectly make him a son of Hwfa
 
Pen. 177, 45 and Pen. 134, 367 cite "Hywel Foel ap Hwfa" as father of Einion
 
33.  Tudor ap Ithel ap Idris, born c. 1140
       His wife is unknown, but he had a son:
 
             47.  Tangwel ap Tudor ap Ithel
 
Pen. 129, 286 and Pen. 128, 186b cite "Tudor ap Ithel ap Idris" as father of Tangwel
 
34.  Dolffyn ap Llewelyn ap Iorwerth, born c. 1130
       His wife is unknown, but he had a son:
 
             48.  Ithel ap Dolffyn ap Llewelyn
 
Pen. 127, 129 and Pen. 128, 602a cite "Dolffyn ap Llewelyn" as father of Ithel, but incorrectly call the father of Dolffyn "Llewelyn Aurdorchog"
 
35.  Iorwerth ap Llewelyn ap Iorwerth, born c. 1135
      His wife is unknown, but he had a son:
 
             49.  Carwed ap Iorwerth ap Llewelyn
 
Pen. 176, 84 & 93; and Pen. 287, 510 cite "Iorwerth ap Llewelyn" as father of Carwed, but incorrectly call the father of Iorwerth "Llewelyn Aurdorchog"
 
36.  Gwgan ap Llewelyn ap Iorwerth, born c. 1130
       His wife is unknown, but he had a son:
 
             50.  Cyfnerth ap Gwgan ap Llewelyn
 
Harl. 1973, 26v cites "Gwgan ap Llewelyn" as father of Cyfnerth, but incorrectly call the father of Gwgan "Llewelyn Aurdorchog"
 
37.  Iorwerth ap Einion ap Rhys Goch, born c. 1140
      He married Sian (c. 1155) ferch Dafydd Fychan (c. 1125) ap Dafydd (c. 1095) ap Ieuan (c. 1065) ap Trahaearn (c. 1035) ap Caradog (c. 1005).  They had a son:
 
             51.  Trahaearn ap Iorwerth ap Einion
 
PF v, pp 120 cites "Iorwerth ap Einion ap Rhys Goch" married "Dafydd Fychan ap Dafydd", as does the entry of Walcot of Bitterly Court in Burke's Landed Gentry.  Both incorrrectly add "of Bacheldre" mistaking him with another Dafydd Fychan born c. 1300.  His correct ancestry is cited in Dwnn i, 274 & 308, although those citations are corrupt beyond Ieuan ap Trahaearn.  Trahaearn ap Iorwerth married a lady of the same family.
 
38.  Iorwerth ap Madog ap Llewelyn, born c. 1125
      His wife is unknown, but he had a son:
 
             52.  Dolffyn ap Iorwerth ap Madog
 
Dwnn ii, 300 note 3 cites "Iorwerth ap Madog ap Llewelyn" as father of Dolffyn
 
39.  Bradwen ap Idnerth ap Dafydd Ysgyd Aur, born c. 1125
       His wife is unknown, but he had a son and 2 daughters:
 
             53.  Ednowain ap Bradwen ap Idnerth
                   Arddun ferch Bradwen ap Idnerth, born c. 1155.  She married Madog (c. 1140) ap Iorwerth (c. 1110) ap Madog (c. 1080) ap Ednowain Bendew II (c. 1050).  We suspect this "Ednowain Bendew" was actually Owain ap Edwin of Tegeingl.
                   Isabel ferch Bradwen ap Idnerth, born c. 1160.  She married Seisyllt (c. 1145) ap Einion (c. 1110) ap Seisyllt (c. 1045).
 
Dwnn ii, 243 cites "Bradwen ap Idnerth ap Dafydd Ysgyd Aur" as father of Ednowain
 
Pen. 287, 271 cites "Arddun ferch Bradwen" married "Madog ap Iorwerth", as do Dwnn ii, 304 & 325.  Neither source extends either ancestry further back, but there are no other known men in Welsh pedigrees named Bradwen and the chronology of our construction fits both spouses.
 
Harl. 1973, 70 & 77 cite "Isabel ferch Bradwen" married "Seisyllt of Meirionydd". But that man was born c. 1045, so she likely married his grandson, Seisyllt of Mathafarn ap Einion ap Seisyllt of Meirionydd.
 
 
GENERATION 10:
 
40.  Cadwgan Goch ap Ithel Y Gwion ap Hwfa, born c. 1160. 
       He married Nesta (c. 1175) ferch Hywel (c. 1145) ap Ithel (c. 1115) ap Madog (c. 1085) ap Rhiryd (c. 1055) ap Bleddyn (c. 1025) ap Cynfyn (c. 990)  They had a son:
 
            54.  Hwfa ap Cadwgan Goch ap Ithel Y Gwion
 
Harl. 2299 cites "Cadwgan Goch ap Y Gwion ap Hwfa" married "Nesta ferch Hywel ap Ithel ap Madog ap Rhiryd ap Bleddyn".  Other sources omit Madog from her ancestry and fail chronologically
 
41.  Cynddelw ap Ithel Y Gwion ap Hwfa, born c. 1155
       His wife is unknown, but he had a son:
 
            55.  Einion ap Cynddelw ap Ithel Y Gwion
 
Pen. 136, 77; Pen. 139(1), 71; and Dwnn ii, 278 call him "Cynddelw ap Ithel Felyn" but he must have been the son of this Ithel three generations later.  Bartrum's chart simply shows 3 generations missing from Ithel Felyn to Cynddelw
 
42.  Iorwerth ap Caswallon ap Hwfa, born c. 1160.
      His wife is unknown but he was living in 1202 and had 3 sons:
 
            56.  Rhys ap Iorwerth ap Caswallon
            57.  Cynwrig ap Iorwerth ap Caswallon
            58.  Caswallon ap Iorwerth ap Caswallon
 
Pen. 131, 52; Pen. 129, 84; and Pen 127, 136 cite "Iorwerth ap Caswallon ap Hwfa" as father of Cynwrig
 
This Iorwerth ap Caswallon was a witness to a 1202 grant of lands to Valle Crucis Abbey
 
43.  Maredudd ap Caswallon ap Hwfa, born c. 1155
      His wife is unknown, but he had a son:
 
            59.  Gruffudd ap Maredudd ap Caswallon
 
Pen. 177, 166 and Pen. 134, 69 cite the father of Gruffudd as "Maredudd ap Hwfa" but Bartrum's chart shows one generation missing with that construction.
 
44.  Bleddyn ap Caswallon ap Hwfa, born c. 1160
      His wife is unknown, but he had a son:
 
            60.  Cynwrig ap Bleddyn ap Caswallon
 
Pen. 287, 504/506 cite "Bleddyn ap Caswallon ap Hwfa" as father of Cynwrig
 
45.  Ieuaf ap Hywel Foel ap Hwfa, born c. 1160
      His wife is unknown, but he had a son:
 
            61.  Hywel y Gwion Gam ap Ieuaf ap Hywel Foel
 
Harl. 2299 cites "Ieuaf ap Hywel Foel ap Hwfa" as father of Y Gwion Gam.  We suggest "y gwion" means "the grandson" and that he bore the same birthname as his grandfather, i.e. Hywel.
 
Pen. 176, 48 makes Y Gwion Gam the son of "Ieuan ap Hwfa", a chronologically impossible construction.  No other sources say Hwfa had a son named either Ieuan or Ieuaf.
 
46.  Einion ap Hywel Foel ap Hwfa, born c. 1165
      His wife is unknown, but he had a son:
 
            62.  Madog ap Einion ap Hywel Foel
 
Pen. 139(1), 87 and Pen. 177, 45 cite "Einion ap Hywel Foel ap Hwfa" as father of Madog
 
47.  Tangwel ap Tudor ap Ithel, born c. 1170
       His wife is unknown, but he had a son:
 
            63.  Meilyr ap Tangwel ap Tudor
 
Pen 131, 286 and Pen. 128, 186b cite "Tangwel ap Tudor ap Ithel" as father of Meilyr
 
48.  Ithel ap Dolffyn ap Llewelyn, born c. 1165
      His wife is unknown, but he had a son:
 
            64.  Deheuwynt ap Ithel ap Dolffyn
 
Pen. 127, 129 and Pen. 128, 602a cite "Ithel ap Dolffyn ap Llewelyn" as father of Deheuwynt, but mistakenly add "Aurdorchog" to Llewelyn
 
49.  Carwed ap Iorwerth ap Llewelyn, born c. 1165
       His wife is unknown, but he had a son:
 
            65.  Iorwerth ap Carwed ap Iorwerth
 
Pen. 176, 93 cites "Carwed ap Iorwerth ap Llewelyn" as father of Iorwerth, but mistakenly adds "Aurdorchog" to Llewelyn
 
50.  Cyfnerth ap Gwgan ap Llewelyn, born c. 1160
      His wife is unknown, but he had a son:
 
            66.  Meilyr ap Cyfnerth ap Gwgan
 
Harl. 1973, 26v cites "Cyfnerth ap Gwgan ap Llewelyn" as father of Meilyr, but mistakenly adds "Aurdorchog" to Llewelyn
 
 
51.  Trahaearn ap Iorwerth ap Einion, born c. 1170
       He served as a captain in the warband of Gwenwynwyn, king of south Powys, for which service he was granted the manor of Garthmyl in Cydewain.  He married Dyddgu (c. 1180) ferch Maredudd (c. 1145) ap Robert (c. 1110) ap Llywarch (c. 1070) ap Trahaearn (c. 1035) ap Caradog (c. 1005). Trahaearn ap Caradog was king of Powys and Gwynedd 1075-1081.  Maredudd ap Robert ap Llywarch was Lord of Cydewain; at his death he was succeeded by a nephew, named Maredudd ap Robert ap Robert, and it was that Maredudd whose obit is recorded in 1244.  Trahaearn and Dyddgu had 5 sons and 2 daughters:
 
           67.  Iorwerth y Gwion ap Trahaearn ap Iorwerth
           68.  Ieuan ap Trahaearn ap Iorwerth
           69.  Ithel Dalfrith ap Trahaearn ap Iorwerth
           70.  Maredudd ap Trahaearn ap Iorwerth
                 Meurig ap Trahaearn ap Iorwerth, born c. 1205. He had a daughter:   
                         Sioned ferch Meurig ap Trahaearn, born c. 1235.  She married Gwilym (c. 1220) ap Aaron (c. 1190) ap Rhys (c. 1160) ap Bleddri (c. 1130) ap Rhys (c. 1095) ap Bleddri (c. 1065) ap Cadifor Fawr (c. 1030) of Blaen Cuch in the commote of Emlyn in Dyfed
                 Alison ferch Trahaearn ap Iorwerth, born c. 1205.  She married Cadwaladr (c. 1195) ap Llewelyn Fychan (c. 1160) ap Llewelyn (c. 1130) ap Einion (c. 1095) ap Llewelyn (c. 1060) ap Meilyr Gryg (c. 1025) of Gregynon in Cydewain descended from Brochwel Ysgithrog.
                 Sian ferch Trahaearn ap Iorwerth, born c. 1210.  She married Madog (c. 1205) ap Trahaearn (c. 1175) ap Gruffudd Goch (c. 1145) ap Gruffudd Fele (c. 1115) ap Madog (c. 1085) ap Idnerth (c. 1050) ap Cadwgan (c. 1020) ap Elystan Glodrydd of Fferlys. 
 
 
Dwnn i, 111 cites "Trahaearn of Garthmyl ap Iorwerth" married "Dyddgu ferch Maredudd ap Robert, Lord of Cydewain".  Pen. 131, 126 extends her ancestry to "Maredudd ap Robert ap Llywarch ap Trahaearn ap Caradog".
 
Dwnn i, 114 & 148 cite "Sioned ferch Meurig ap Trahaearn ap Iorwerth" married "Gwilym ap Aaron ap Rhys ap Bleddri".  Pen. 129, 299 & 304 extend his ancestry to "Rhys ap Bleddri ap Cadifor Fawr" but Bartrum's chart shows that to be chronologically impossible.  Our work finds Gwilym occurs in a cousin line, the son of Aaron ap Rhys ap Bleddri ap Rhys ap Bleddri, not of the Sir Aaron ap Rhys ap Bleddri born c. 1130.
 
Dwnn ii, 300 cites "Alison ferch Trahaearn ap Iorwerth" married "Cadwaladr ap Llewelyn Fychan ap Llewelyn ap Einion ap Llewelyn ap Meilyr Gryg".  Bartrum's chart incorrectly attaches Cadwaladr to the Llewelyn ap Meilyr Gryg of c. 1190.  Bartrum, like all others, confuse the Meilyr Gryg of c. 1190 with the Meilyr Gryg of c. 1025 since the same 5-name string begins with both men.
 
Bodleian Add. C.177, 3 cites "Sian ferch Trahaearn ap Iorwerth" married "Madog ap Trahaearn ap Gruffudd Goch", while Pen. 131, 65;Pen. 127, 137 & Pen. 128, 830a extend his ancestry to "Madog ap Trahaearn ap Gruffudd Goch ap Gruffudd Fele ap Madog ap Idnerth ap Cadwgan ap Elystan Glodrydd".  However, Pen. 133, 61 makes him "Madog ap Trahaearn ap Gruffudd Fele ap Llewelyn ap Madog ap Llewelyn ap Cadwgan ap Elystan".  Either works chronologically.
 
 
 
52.  Dolffyn ap Iorwerth ap Madog, born c. 1155
      His wife is unknown, but he had a son:
 
              71.  Llewelyn ap Dolffyn ap Iorwerth
 
Pen 127, 63 and Pen. 128, 272a cite "Dolffyn ap Iorwerth" as father of Llewelyn; they attach Iorwerth directly to Llewelyn Aurdorchog, while Dwnn ii, 300 note 3 says this was Dolffyn ap Iorwerth ap Madog descended from Ithel Hen
 
53.  Ednowain ap Bradwen ap Idnerth, born c. 1155 
      He married first, Marged (c. 1165) ap Cynan (c. 1130) ap Owain Gwynedd (c. 1100)  For his services as penteulu for Dafydd ap Owain Gwynedd, he was granted most of the commote of Tal-y-bont in Meirionydd.
      He married secondly, Sian (c. 1160) ap Philip (c. 1120) ap Uchdryd of Cyfeiliog (c. 1085) ap Uchdryd (c. 1055) ap Edwin of Tegeingl (c. 1020). 
      Ednowain was later recognized as one of the 15 Founders of Noble Tribes of Gwynedd as the last in a long line of men who served as battle leaders for kings of Powys and Gwynedd.  Although he had a number of children, it is appropriate that a new pedigree should be cast to begin with him and we shall not continue with his family in this narrative.
 
Dwnn i, 39 cites "Ednowain ap Bradwen" married "Marged ferch Cynan ap Owain Gwynedd"
 
Dwnn ii, 239 cites "Wife of Ednowain ap Bradwen was Sian ferch Philip ap Uchdryd of Cyfeiliog"
 
Dwnn ii, 243 cites "Ednowain ap Bradwen ap Idnerth ap Dafydd Ysgyd Aur".  Other sources derive Bradwen from Mael ap Bleddyn and make him a brother of Peredur ap Mael, a man born c. 1080.  But Bradwen was born about 75 years later than Mael and 45 years later than Peredur.  A third group of sources derive Bradwen from Idnerth ap Edryd ap Aeddan, a man born c. 1040 and chronologically impossible.  Bartrum rejected the Dwnn citation simply because he dates Llewelyn Aurdorchog a full generation too late, but it is the only ancestry which works chronologically.
     
GENERATION 11:
 
54.  Hwfa ap Cadwgan Goch ap Ithel Y Gwion, born c. 1190
      His wife is unknown, but he had 2 sons:
 
             72.  Cadwgan y Gwion ap Hwfa ap Cadwgan Goch
             73.  Jonas ap Hwfa ap Cadwgan Goch
 
All sources omit one of the repeating 3-name strings in "Cadwgan Goch ap Gwion ap Hwfa ap Cadwgan Goch ap Gwion ap Hwfa ap Ithel Felyn", but the two wives assigned to Cadwgan Goch occur 3 generations apart.  Furthermore, the family descended from Jonas ap Hwfa point to a birthdate c. 1225 for him, and Pen. 128, 216a & 638a call him "Jonas ap Hwfa ap Ithel Felyn" which is chronologically impossible.
 
55.  Einion ap Cynddelw ap Ithel Y Gwion, born c. 1185
      His wife is unknown, but he had a son:
 
              74.  Llewelyn ap Einion ap Cynddelw
 
Pen. 136, 77; Pen. 139(1), 71; and Pen. 139(2), 233 cite "Einion ap Cynddelw ap Ithel Felyn", but Bartrum's charts show 3 generations missing in that construction.  We make his grandfather to be Ithel y Gwion, not Ithel Felyn. Those sources make Llewelyn the son of this Einion
 
56.  Rhys ap Iorwerth ap Caswallon, born c. 1195
      His wife is unknown, but he had a son:
 
              75.  Owain Wynn ap Rhys ap Iorwerth
 
Dwnn ii, 300 cites "Rhys ap Iorwerth" as father of Owain Wynn. 
 
57.  Cynwrig ap Iorwerth ap Caswallon, born 1195
       His wife is unknown, but he had a son:
 
              76.  Gronwy ap Cynwrig ap Iorwerth
 
Pen. 128, 147b & 272b; Pen 132, 191 cite "Cynwrig ap Iorwerth ap Caswallon"

58.  Caswallon ap Iorwerth ap Caswallon, born c. 1190
       He married Annes (c. 1205) ferch Cowryd (c. 1175) ap Cadfan (c. 1140) of Dyffryn Clwyd.  They had a son:
 
              77.  Iorwerth ap Caswallon ap Iorwerth
 
All sources omit one pair of "Iorwerth ap Caswallon" from this family, Bartrum simply indicating 2 generations are missing in his chart.  He omits Annes altogether since she didn't fit the single Caswallon he lists.
 
PF ii, pp 347 (this work cites the Cae Cyriog Ms as it's source) says that "Annest ferch Cowryd ap Cadfan" married "Caswallon ap Hwfa".  We emend that to "Caswallon ap Iorwerth ap Caswallon ap Hwfa", restoring the two generations known to be missing from the pedigree.
 
59.  Gruffudd ap Maredudd ap Caswallon, born c. 1185
       His wife is unknown, but he had a son:
 
              78.  Heilyn ap Gruffudd ap Maredudd
 
Pen. 176, 334; Pen. 134, 69; Pen. 177, 166 & Pen. 135.293 cite "Gruffudd ap Maredudd" as the father of Heilyn.  They incorrectly make Maredudd a son of Hwfa, omitting Caswallon.
 
60.  Cynwrig ap Bleddyn ap Caswallon, born c. 1195
       His wife is unknown, but he had a son:
 
              79.  Madog Goch ap Cynwrig ap Bleddyn
 
Pen. 287, 506 cites "Cynwrig ap Bleddyn ap Caswallon" as the father of Madog Goch

      His wife is unknown, but he had a son:
 
              80.  Ithel ap Hywel Y Gwion Gam ap Ieuaf
 
Pen. 176, 48 cites "Y Gwion Gam ap Ieuan" as the father of Ithel.  As shown earlier, other sources say the father of Y Gwion Gam was Ieuaf, not Ieuan.
 
62.  Madog ap Einion ap Hywel Foel, born c. 1200
      His wife is unknown, but he had 2 sons:
 
              81.  Llewelyn ap Madog ap Einion
              82.  Hwfa ap Madog ap Einion
 
Pen. 287, 500 and Pen. 139(1), 87 cite "Madog ap Einion ap Hywel Foel ap Hwfa" as the father of Llewelyn.
 
63.  Meilyr ap Tangwel ap Tudor, born c. 1205
      His wife is unknown, but he had 2 sons:

Pen. 127, 129 cites "Deheuwynt ap Ithel ap Dolffyn" as the father of Pyll
 
65.  Iorwerth ap Carwed ap Iorwerth, born c. 1195
      He was granted the manor of Llanelidan by the Bishop of Bangor. His wife is unknown but he had a son:
 
              86.  Hywel ap Iorwerth ap Carwed
 
Pen. 176, 93 cites "Iorwerth ap Carwed ap Iorwerth" as the father of Hywel
 
66.  Meilyr ap Cyfnerth ap Gwgan, born c. 1190
      His wife is unknown, but he had a son:
 
              87.  Trahaearn ap Meilyr ap Cyfnerth
 
Harl. 1973, 26 cites "Meilyr ap Cyfnerth ap Gwgan" as the father of Trahaearn
 
67.  Iorwerth Y Gwion ap Trahaearn ap Iorwerth, born c. 1200
      He married Jane (c. 1215) daughter of Sir Peter Corbet (c. 1185) son of Sir Robert Corbet (c. 1155) son of William Corbet (c. 1120) son of William Corbet (c. 1090) son of Roger Corbet (c. 1060) son of Hugh Corbet of Pais de Caux (c. 1030), this Hugh having come from Normandy as a captain serving under Sir Roger of Montgomery at the battle of Hastings in 1066.  The Corbet family held lands called Caus in Shropshire, serving its patron when the latter became Earl of Shrewsbury.  Iorwerth "the grandson" and Jane had a son and a daughter:
 
            88.  Iorwerth Fychan ap Iorwerth Y Gwion ap Trahaearn
                  Efa ferch Iorwerth Y Gwion ap Trahaearn, born c. 1230.  She married Henwyn (c. 1215) ap Ithel Aur Gleddf (c. 1180) ap Hywel (c. 1150) ap Gruffudd (c. 1115) ap Ednyfed (c. 1085) ap Idnerth (c. 1050) ap Cadwgan (c. 1020) ap Elystan Glodrydd (c. 990)
 
Dwnn i, 111 cites "Iorwerth ap Trahaearn ap Iorwerth" of Garthmyl married "Jane, daughter of Sir Peter Corbet".  We believe Sir Peter was the eldest son of Sir Robert Corbet of Caus (obit 1222) and, having no son, was succeeded as Lord of Caus by his brother, Sir Robert II.  The early part of the Corbet pedigree is in some disarray, but the 1623 Visitation of Shorpshire pp. 133/139 cites "Robert Corbet son of Robert son of William son of Roger son of Corbet the Norman" which is one generation too short for the family which follows.  Other sources mention a William son of William son of Roger son of Corbet the Norman.
 
Dwnn i, 297 cites "Efa ferch Iorwerth ap Trahaearn of Garthmyl" married "Henwyn ap Ithel Aur Gledde ap Hywel ap Gruffudd ap Ednyfed ap Idnerth ap Cadwgan ap Elystan Glodrydd"
 
Harl. 1973, 119 cites "Gwion ap Trahaearn" as the father of Iorwerth.  Since this Gwion was actually Iorwerth y Gwion, his son was Iorwerth Fychan
 
68.  Ieuan ap Trahaearn ap Iorwerth, born c. 1200
      His wife is unknown, but he had a daughter:
 
                 Efa ferch Ieuan ap Trahaearn, born c. 1230.  She married Einion (c. 1215) ap Ieuan (c. 1185) ap Iorwerth Goch (c. 1150) ap Ystrwyth (c. 1115) ap Ednowain (c. 1085) ap Gwrydr (c. 1050) ap Dyfnant (c. 1015) ap Meurig (c. 985) ap Iddon (c. 955) ap Iddig (c. 925) ap Llywarch (c. 890) ap Llofan (c. 860) ap Cilmin Droed Ddu (c. 830) ap Cadrod (c. 795) which Cadrod was a brother of Merfyn Frych who usurped the kingship of Gwynedd in 816.
 
Dwnn ii, 147 cites "Efa ferch Ieuan ap Trahaearn ap Iorwerth" married "Einion ap Ieuan ap Iorwerth Goch ap Ystrwyth ap Ednowain ap Gwrydr ap Dyfnant ap Iddon ap Iddig ap Llywarch ap Llofan ap Cilmin "while HLG 8a inserts "Meurig" as the father of Dyfnant.
 
69.  Ithel Dalfrith ap Trahaearn ap Iorwerth, born c. 1200
      He settled on patrimonial lands in Ystrad Alun which his ancestors had leased out since moving to south Powys.  His wife is unknown, but he had a son and a daughter:
 
              89.  Llewelyn ap Ithel Dalfrith ap Trahaearn
                    Marged ferch Ithel Dalfrith ap Trahaearn, born c. 1235.  She married Hwfa (c. 1225) ap Iorwerth (c. 1195) ap Gruffudd of Bersham (c. 1165) ap Ieuaf (c. 1130) ap Ninniaw (c. 1095) descended from Tudor Trevor.
 
Pen. 127, 136; Pen. 129, 111; Pen. 127, 133 cite "Ithel Dalfrith ap Trahaearn Goch" and no sources extend his ancestry.  His lands in Ystrad Alun suggest he descended from Llewelyn Aurdorchog, and some writers incorrectly add "Goch" to Trahaearn ap Iorwerth of Garthmyl...also descended from Llewelyn Aurdorchog.  The chronology fits our making Ithel Dalfrith a son of that Trahaearn, and Ithel was a favored name in that extended family.
 
The same sources cited next above make Llewelyn a son of Ithel Dalfrith
 
Pen. 128, 147b cites "Marged ferch Ithel Dalfrith" married "Hwfa ap Iorwerth ap Ieuaf", a construction which is 1 generation deficient.  Pen. 127, 131a and 137b identify a "Hwfa ap Iorwerth ap Gruffudd ap Ieuaf ap Ninniaw" who fits chronologically, and we believe the marriage citation omitted Gruffudd from the ancestry of the Hwfa who married Marged.
 
70.  Maredudd ap Trahaearn ap Iorwerth, born c. 1200
        As the youngest son, he inherited the manor house at Garthmyl.  His wife is unknown, but he had a son:
 
              90.  Gruffudd ap Maredudd ap Trahaearn
 
Montgomeryshire Collections, vii, 55 cites "Maredudd ap Trahaearn ap Iorwerth" as the ancestor of the Jones family of Garthmyl
 
Harl. 1973, 28 cites "Maredudd ap Trahaearn" as the father of Gruffudd
 
71.  Llewelyn ap Dolffyn ap Iorwerth, born c. 1185
      He married Tangwystl (c. 1195) ferch Iorwerth (c. 1160) ap Gronwy (c. 1130) ap Hwfa (c. 1095). See #23 above. They had a son and 3 daughters:
 
               91.  Ithel ap Llewelyn ap Dolffyn
                     Efa ferch Llewelyn ap Dolffyn, born c. 1215.  She married Eunydd of Gwerngwy (c. 1200) ap Gwrgeneu (c. 1165) ap Heilyn (c. 1135) ap Eunydd of Trefalun (c. 1105) ap Heilyn (c. 1075) ap Eunydd of Dyffryn Clwyd (c. 1045)
                     Sissely ferch Llewelyn ap Dolffyn, born c. 1215.  She married Llewelyn (c. 1200) ap Moreiddig (c. 1165) ap Moreiddig (c. 1125) ap Sandde Hardd (c. 1095) of Mortyn.
                     Tangwystl ferch Llewelyn ap Dolffyn, born c. 1220.  She married Iorwerth (c. 1215) ap Cynwrig Ddewis Herod (c. 1185) ap Cowryd Perfarch (c. 1150) ap Iarddur (c. 1115) ap Llewelyn Meudwy(c. 1085) ap Hedd (c. 1050) ap Alunog (c. 1020) descended from Tudwal Gloff ap Rhodri Mawr.
 
Arch Cam 1932, pp 242 cites "Efa ferch Llewelyn ap Dolffyn" married "Eunydd (ap) Gwerngwy", which inserts an "ap" between Eunydd and his residence in Gwerngwy, Dyffryn Clwyd.  He is called Eunydd Gwerngwy in Pen. 128, 398a.
 
Montgomeryshire Collections vii, pp 54 cites "Sissely ferch Llewelyn ap Dolffyn" married "Llewelyn ap Moreiddig ap Sandde Hardd".  The families descended from Llewelyn ap Moreiddig all occur one generation later than those descended from Hywel ap Moreiddig ap Sandde Hardd and we suggest there was a Moreiddig ap Moreddig ap Sandde Hardd
 
Pen. 127, 63 & 64 cite "Tangwystl ferch Llewelyn ap Dolffyn" married "Iorwerth ap Cynwrig Ddewis Herod ap Cowryd". 
 

GENERATION 12:
 
72.  Cadwgan Y Gwion ap Hwfa ap Cadwgan Goch, born c. 1220
      His wife is unknown, but he had 2 sons:
 
              92.  Cadwgan Goch ap Cadwgan Y Gwion ap Hwfa
              93.  Cadwgan Frych ap Cadwgan Y Gwion ap Hwfa
 
Pen. 128, 139a cites "Gwion ap Hwfa" as the father of Cadwgan Goch.  The family which follows dates this "Gwion" to c. 1220 and we make him the son of Hwfa ap Cadwgan Goch ap Ithel y Gwion ap Hwfa ap Ithel Felyn.
 
73.  Jonas ap Hwfa ap Cadwgan Goch, born c. 1225
       His wife is unknown, but he had 2 sons:
 
               94.  Ithel ap Jonas ap Hwfa
               95.  Madog ap Jonas ap Hwfa
 
Dwnn ii, 228 cites "Jonas ap Hwfa" as the father of Ithel
 
Pen. 128, 216a cites "Jonas ap Hwfa" as the father of Madog
 
All sources mistake Hwfa, father of Jonas, with Hwfa ap Ithel Felyn by omitting 3 generations.  Jonas was a brother of (Cadwgan) y Gwion ap Hwfa ap (Ithel) y Gwion ap Hwfa ap Ithel Felyn.
 
74.  Llewelyn ap Einion ap Cynddelw, born c. 1215
       His wife is unknown, but he had a son:
 
               96.  Iorwerth ap Llewelyn ap Einion
 
Pen. 136, 77 cites "Llewelyn ap Einion ap Cynddelw" as the father of Iorwerth
 
75.  Owain Wynn ap Rhys ap Iorwerth, born c. 1230
       His wife is unknown, but he had 2 sons:
 
               97.  Owain Fychan ap Owain Wynn ap Rhys
               98.  Rhys Lloyd ap Owain Wynn ap Rhys
 
Dwnn ii, 300 cites "Owain Wynn ap Rhys ap Iorwerth" as the father of Owain Fychan
 
76.  Gronwy ap Cynwrig ap Iorwerth, born c. 1225
      His wife is unknown, but he had a son:
 
               99.  Madog ap Gronwy ap Cynwrig
 
Harl. 1972, 78; Pen. 131, 52; Pen. 129, 84; Pen 127, 136 cite Madog as a son of "Gronwy ap Cynwrig" and the three Peniarth manuscripts extend his ancestry to "Gronwy ap Cynwrig ap Iorwerth"
 
77.  Iorwerth ap Caswallon ap Iorwerth, born c. 1220
      He married Gwenhwyfar (c. 1230) ferch Cuhelyn (c. 1200) ap Rhun (c. 1170) ap Einion Efell (c. 1135); Einion Efell was a base son of Madog ap Maredudd ap Bleddyn ap Cynfyn.  They had a son:
 
              100.  Cynwrig ap Iorwerth ap Caswallon
 
PF ii, 348 (citing the Cae Cyriog Ms) says "Gwenhwyfar ferch Cuhelyn ap Rhun ap Einion Efell" married "Iorwerth ap Caswallon ap Hwfa", omitting one pair of "Iorwerth ap Caswallon" from the pedigree.  Bartrum's charts omit Gwenhwyfar since she didn't fit timewise in his flawed construction.
 
PF v, 91 (citing BM Add 9864) cites the same marriage, but also confuses this Iorwerth ap Caswallon with the earlier same-named man who was living in 1202
 
78.  Heilyn ap Gruffudd ap Maredudd, born c. 1220
      His wife is unknown, but he had a son:
 
              101.  Heilyn Fychan ap Heilyn ap Gruffudd
 
Pen. 176, 334; Pen. 139(1), 82; Pen. 134, 69; Pen. 177. 166; Pen. 135, 293 cite "Heilyn ap Gruffudd ap Maredudd" as the father of Heilyn Fychan
 
79.  Madog Goch ap Cynwrig ap Bleddyn, born c. 1225
      His wife is unknown, but he had a son:
 
              102.  Ieuan ap Madog Coch ap Cynwrig 
 
Pen. 287, 506 cites "Madog Goch ap Cynwrig ap Bleddyn" as the father of Ieuan 
 
80.  Ithel ap Hywel Y Gwion Gam ap Ieuaf, born c. 1220
      His wife is unknown, but he had 4 sons:
 
              103.  Iorwerth ap Ithel ap Hywel Y Gwion Gam
              104.  Ieuan ap Ithel ap Hywel Y Gwion Gam
              105.  Llewelyn Y Stwg ap Ithel ap Hywel Y Gwion Gam
              106.  Gwilym ap Ithel ap Hywel Y Gwion Gam
 
Cardiff 3.8, 157 cites "Ithel ap Hywel Foel" as the father of Iorwerth. That construction is 2 generations deficient, and we think it was Hywel, the grandson of Hywel Foel which is meant, i.e. "Ithel ap Hywel y Gwion Gam ap Ieuaf ap Hywel Foel"
 
Pen. 134, 147 cites "Ieuan ap Ithel to Hwfa"; Bartrum incorrectly assumed that Hwfa ap Cynddelw was meant and places Ieuan's family on chart Hwfa 1.
 
Pen. 176, 48 and Pen, 287, 498 cite "Ithel ap Y Gwion Gam" as the father of Gwilym
 
81.  Llewelyn ap Madog ap Einion, born c. 1235
      His wife is unknown, but he had a son:
 
              107.  Iolyn ap Llewelyn ap Madog
 
Pen. 287, 500; Pen. 139(1), 87 cite "Llewelyn ap Madog ap Einion" as the father of Iolyn
 
82.  Hwfa ap Madog ap Einion, born c. 1230
      His wife is unknown, but he had a son:
 
              108.  Hywel ap Hwfa ap Madog
 
See #174 below; this branch of the family contains a repeating 4-name string of "Madog ap Einion ap Hywel ap Hwfa" ap "Madog ap Einion ap Hywel Foel ap Hwfa" ap Ithel Felyn.
 
83.  Madog Goch ap Meilyr ap Tangwel, born c. 1235
      His wife is unknown, but he had a son:
 
              109.  Meilyr ap Madog Goch ap Meilyr
 
Harl. 1977, 123v cites this line of the family as "Hywel Goch ap Rhiwallon ap Meilyr ap Tangwel", skipping from Meilyr ap Madog Goch to Meilyr ap Tangwel.  Bartrum's chart shows 2 generations missing in that construction.
 
84.  Madog Heddwch ap Meilyr ap Tangwel, born c. 1240
      He married Tangwystl (c. 1250) ferch Madog (c. 1210) ap Einion (c. 1180) ap Madog (c. 1150) ap Gwylog (c. 1120) ap Eginyr (c. 1085) ap Urien (c. 1055) ap Eginyr (c. 1025) ap Lles (c. 995) ap Idnerth Benfras of Maesbrook (c. 960).  They had a 2 sons:
   
              110.  Dafydd ap Madog Heddwch ap Meilyr
              111.  Ithel ap Madog Heddwch ap Meilyr
 
Harl. 1971, 180 cites "Madog Heddwch ap Meilyr ap Tangwel" married "Tangwystl ferch Madog ap Gwylog" which skips from Madog ap Einion to Madog ap Gwylog.  Her ancestry is continued in Pen. 135, 285 and Pen. 128, 87b as "Gwylog ap Eginyr ap Lles ap Idnerth Benfras", which skip from Eginyr ap Urien to Eginyr ap Lles.  Together, these citations omit 4 generations.  No extant pedigrees cast for the family of Idnerth Benfras are, as they stand, even close to being chronologically stable.
 
Dwnn i, 322 cites "Madog Heddwch ap Meilyr ap Tangwel" as the father of Dafydd
 
Pen. 287, 509 cites "Madog Heddwch ap Meilyr ap Tangwel" ap the father of Ithel
 
85.  Pyll ap Deheuwynt ap Ithel, born c. 1230
      His wife is unknown, but he had a son:
 
              112.  Madog ap Pyll ap Deheuwynt
 
Pen. 127, 129 cites "Pyll ap Deheuwynt ap Ithel" as the father of Madog
 
86.  Hywel ap Iorwerth ap Carwed, born c. 1230
       His wife is unknown, but he had a son:
 
              113.  Gwyn ap Hywel ap Iorwerth
 
Pen. 176, 84 & 93; Pen 287, 510 cite "Hywel ap Iorwerth ap Carwed" as the father of Gwyn
 
87.  Trahaearn ap Meilyr ap Cyfnerth, born c. 1220
       His wife is unknown, but he had a son:
 
              114.  Gwgan ap Trahaearn ap Meilyr
 
Harl. 1973, 26 cites "Trahaearn ap Meilyr ap Cyfnerth" as the father of Gwgan
 
88.  Iorwerth Fychan ap Iorwerth Y Gwion ap Trahaearn, born c. 1230
      His wife is unknown, but he had 3 sons:
 
              115.  Trahaearn Goch ap Iorwerth Fychan ap Iorwerth Y Gwion
              116.  Ieuan Goch ap Iorwerth Fychan ap Iorwerth Y Gwion
              117.  Rhys ap Iorwerth Fychan ap Iorwerth Y Gwion
              118.  Ieuan Fychan ap Iorwerth Fychan ap Iorwerth Y Gwion
         
Harl. 1973, 119 cites "Ieuan ap Iorwerth ap Gwion"; since Gwion was actually Iorwerth y Gwion, we read this as "Ieuan ap Iorwerth Fychan ap Iorwerth Y Gwion". We added the "Fychan" to this Ieuan since he appears to have had a brother called Ieuan Goch.  It is possible both these Ieuans were a single person, but we date them 5 years apart.
 
Dwnn i, 21 cites "Ieuan Goch ap Iorwerth ap Trahaearn" but the family which follows chronologically requires Ieuan Goch to occur in the 3rd generation after Trahaearn, so we make him a son of Iorwerth Fychan ap Iorwerth.
 
Comments of the other sons shown for Iorwerth Fychan will follow the entry for those sons.
 
89.  Llewelyn ap Ithel Dalfrith ap Trahaearn, born c. 1230
      His wife is unknown, but he had a son:
 
              119.  Llywarch ap Llewelyn ap Ithel Dalfrith
              120.  Einion ap Llewelyn ap Ithel Dalfrith
 
Pen. 127, 36 and Pen. 176, 123 & 221 cite "Llewelyn ap Ithel Dalfrith" as the father of Llywarch
 
Pen. 129, 111; Pen. 127, 133; Pen. 128, 156a & 612a cite "Llewelyn ap Ithel Dalfrith" as the father of Einion. 
 
Llywarch ap Llewelyn had a son, Einion, who is confused with his brother Einion but the two men named Einion are found in wholly different sources and are not merely the result of a name dropped from one set of manuscripts as Bartrum supposed.
 
90.  Gruffudd ap Maredudd ap Trahaearn, born c. 1240
       His wife is unknown, but he had a son:
 
              121.  Iorwerth ap Gruffudd ap Maredudd
 
Harl. 1973, 28 cites "Gruffudd ap Maredudd ap Trahaearn"
 
Pen. 287, 423 cites the heiress of Garthmyl who married an ancestor of the Jones family of Garthmyl as "Marged ferch Ieuan Fwyndeg ap Ieuan ap Dafydd ap Iorwerth".  Iorwerth fits chronologically as a son of Gruffudd ap Maredudd ap Trahaearn.  Our construction follows possession of the manor at Garthmyl from Maredudd ap Trahaearn down to Marged, heiress of Garthmyl
 
91.  Ithel ap Llewelyn ap Dolffyn, born c. 1220
      His wife is unknown, but he had a son:
 
              122.  Philip ap Ithel ap Llewelyn
 
Pen. 176, 362 and Pen. 177, 45 cite "Ithel ap Llewelyn ap Dolffyn" as the father of Philip
 
GENERATION 13:
 
92.  Cadwgan Goch ap Cadwgan Y Gwion ap Hwfa, born c. 1250
      He married Dyddgu (c. 1260) ferch Ithel (c. 1225) ap Hywel (c. 1195) ap Moreiddig (c. 1165) ap Moreiddig (c. 1125) ap Sandde Hardd of Mortyn (c. 1095).  They had a son and a daughter:
 
              123.  Cadwgan Ddu ap Cadwgan Goch ap Cadwgan Y Gwion
                      Gwen ferch Cadwgan Goch ap Cadwgan Y Gwion, born c. 1280.  She married Ednyfed Goch (c. 1265) ap Cynwrig (c. 1230) ap Gruffudd Fychan (c. 1200) ap Gruffudd (c. 1165) ap Einion (c. 1135) ap Ednyfed of Broughton (c. 1100) ap Cynwrig (c. 1065) ap Rhiwallon (c. 1030) descended from Tudor Trevor.
 
Pen. 128, 139a cites "Cadwgan Goch ap Gwion ap Hwfa" married "Dyddgu ferch Ithel ap Hywel ap Moreiddig", but this cannot be Hywel ap Moreiddig ap Sandde Hardd.  We suggest Moreiddig ap Sandde had a son also named Moreiddig, as several family pedigrees point to a Moreiddig born c. 1165 descended from Sandde Hardd.
 
Pen. 128, 139a also cites "Gwen ferch Cadwgan Goch ap Gwion" married "Ednyfed Goch ap Cynwrig ap Gruffudd Fychan", while Pen. 131, 54 extends his ancestry as "Cynwrig ap Gruffudd Fychan ap Gruffudd ap Einion ap Ednyfed ap Cynwrig ap Rhiwallon"
 
Pen. 129, 111 and Pen. 127, 132 cite "Cadwgan Goch ap Gwion" as the father of Cadwgan Ddu"
 
93.  Cadwgan Frych ap Cadwgan Y Gwion ap Hwfa, born c. 1255
      His wife is unknown, but he had a son:
 
               124.  Madog ap Cadwgan Frych ap Cadwgan Y Gwion
 
Pen. 128, 906a cites "Cadwgan Frych ap Cadwgan Goch ap Gwion" as the father of Madog.  But the ensuing family dates Cadwgan Frych to c. 1255 and he must have been the brother of Cadwgan Goch, not his son. 
 
94.  Ithel ap Jonas ap Hwfa, born c. 1255
      His wife is unknown, but he had a son:
 
               125.  Madog ap Ithel ap Jonas
 
Dwnn ii, 228 cites "Ithel ap Jonas ap Hwfa" as the father of Madog
 
95.  Madog ap Jonas ap Hwfa, born c. 1260
      His wife is unknown, but he had a son:
 
               126.  Maredudd ap Madog ap Jonas
 
Pen. 128, 216a cites "Madog ap Jonas ap Hwfa" as the father of Maredudd
 
96.  Iorwerth ap Llewelyn ap Einion, born c. 1245
      His wife is unknown, but he had a son:
 
               127.  Llywarch ap Iorwerth ap Llewelyn

Pen. 136, 77 cites "Iorwerth ap Llewelyn ap Einion" as the father of Llywarch
 
97.  Owain Fychan ap Owain Wynn ap Rhys, born c. 1260
      His wife is unknown, but he had a son:
 
               128.  Madog Goch ap Owain Fychan ap Owain Wynn
 
Dwnn ii, 300 cites "Owain Fychan ap Owain Wynn ap Rhys" as the father of Madog Goch
 
98.  Rhys Lloyd ap Owain Wynn ap Rhys, born c. 1265
        His wife is unknown, but he resided at Coed yr Erfed in Tegeingl and had a son:
 
               129.  Dafydd ap Rhys Lloyd ap Owain Wynn
 
Dwnn i, 291 cites "Rhys Lloyd ap Rhys ap Iorwerth" as the father of Dafydd.  Based on the timeline for his descendants, we believe that citation omits Owain Wynn as the father of Rhys Lloyd
 
99.  Madog ap Gronwy ap Cynwrig, born c. 1255
        His wife is unknown, but he had a son:
 
                       Hywel ap Madog ap Gronwy, born c. 1285.  His wife is unknown, but he had a daughter:
                                
                                Gwenhwyfar ferch Hywel ap Madog, born c. 1315.  She married Hywel (c. 1300) ap Ithel Goch (c. 1265) ap Madog (c. 1230) ap Llewelyn (c. 1195) ap Ithel (c. 1165) ap Heilyn (c. 1135) ap Eunydd of Trefalun (c. 1105) ap Heilyn (c. 1075) ap Eunydd of Dyffryn Clwyd (c. 1045)
 
Harl. 1972, 78 cites "Gwenhwyfar ferch Hywel ap Madog ap Gronwy" married "Hywel ap Ithel Goch ap Madog ap Llewelyn ap Ithel ap Heilyn ap Eunydd" but connects that Eunydd to his grandfather, Eunydd ap Morien.
 
100.  Cynwrig ap Iorwerth ap Caswallon, born c. 1255.
        He married Janet (c. 1265), daughter of Henry de Lacy, the latter died in 1312 and was born c. 1230.  Cynwrig had a son:
 
                130.  Gronwy ap Cynwrig ap Iorwerth
 
Pen. 128, 139a, 213b & 252b cite "Janet daughter of Henry de Lacy" married "Cynwrig ap Iorwerth ap Caswallon" but incorrectly assume this was Caswallon ap Hwfa
 
101.  Heilyn Fychan ap Heilyn ap Gruffudd, born c. 1250
        His wife is unknown, but he had a son:
 
                131.  Hwfa ap Heilyn Fychan ap Heilyn
 
Pen. 176, 334 cites "Heilyn Fychan ap Heilyn ap Gruffudd" as the father of Hwfa
 
102.  Ieuan ap Madog Goch ap Cynwrig, born c. 1260
        His wife is unknown, but he had a son:
 
                132.  Iolyn ap Ieuan ap Madog Goch
 
Pen 287, 506 cites "Ieuan ap Madog Goch ap Cynwrig" as the father of Iolyn
 
103.  Iorwerth ap Ithel ap Hywel Y Gwion Gam, born c. 1250
        His wife is unknown, but he had a son:
 
                133.  Iorwerth Fychan ap Iorwerth ap Ithel
 
Cardiff 3.8, 157 cites "Iorwerth ap Ithel" as the father of Iorwerth Fychan
 
104.  Ieuan ap Ithel ap Hywel Y Gwion Gam, born c. 1250
        His wife is unknown, but he had a son:
 
                134.  Ithel ap Ieuan ap Ithel
 
Bartrum incorrectly places this family on his chart Hwfa 1.
 
Pen. 134, 147 cites "Ieuan ap Ithel from Hwfa" as the father of Ithel.  This is the only Ieuan ap Ithel descended from a Hwfa who fits chronologically.
 
105.  Llewelyn Y Stwg ap Ithel ap Hywel Y Gwion Gam, born c. 1250
        Often called "Ystwch" (the pail or bucket), his wife is unknown but he had 2 sons:
 
                135.  Dafydd Fychan ap Llewelyn Y Stwg ap Ithel
                136.  Ieuan ap Llewelyn Y Stwg ap Ithel
 
Pen. 287, 499; Pen. 134, 116; Dwnn ii, 302 cite "Ystwg ap Ithel Felyn" but he lived nearly 200 years later than the Ithel Felyn who was Lord of Ial and Ystrad Alun.  We think his father was Ithel ap Y Gwion Gam descended from Ithel Felyn, and his timeline fits well as a 4th son of that later Ithel.
 
Pen. 134, 116 cites "Llewelyn Stwg  ap Ithel (Felyn)" as the father of Dafydd Fychan
 
Dwnn ii, 302 cites "Ystwch ap Ithel (Felyn)" as the father of Ieuan, while Pen. 287, 506 calls this son "Iddon" and Cardiff 3.8, 156 calls him "Adda".  We favor the earlier Dwnn spelling of "Ieuan".
 
106.  Gwilym ap Ithel ap Hywel Y Gwion Gam, born c. 1255
        His wife is unknown, but he had a son:
 
                137.  Cadwgan ap Gwilym ap Ithel
 
Pen. 176, 48 and Pen 139(2), 216 cite "Gwilym ap Ithel ap Y Gwion Gam" as the father of Cadwgan
 
107.  Iolyn ap Llewelyn ap Madog, born c. 1265
        His wife is unknown, but he had a son:
 
                138.  Deio ap Iolyn ap Llewelyn
 
Pen. 287, 500 and Pen 139(1), 87 cite "Iolyn ap Llewelyn ap Madog" as the father of Deio
 
108.  Hywel ap Hwfa ap Madog, born c. 1260
        His wife is unknown, but he had a son:
 
                139.  Einion ap Hywel ap Hwfa
 
See notes with #139 below
 
109.  Meilyr ap Madog Goch ap Meilyr, born c. 1270
        His wife is unknown, but he had a son:
 
               140.  Rhiwallon ap Meilyr ap Madog Goch
 
See the source note to #83 above.  Only our construction is sound chronologically
 
110.  Dafydd ap Madog Heddwch ap Meilyr, born c. 1270
        He married Dyddgu (c. 1285) ferch Deio (c. 1255) ap Madog (c. 1225) ap Iorwerth Foel (c. 1195) ap Ieuaf Sais (c. 1165) ap Cyfnerth (c. 1135) ap Iddon (c. 1105) ap Trahaearn (c. 1075) ap Iorwerth (c. 1040) ap Mael (c. 1010) ap Pasgen (c. 980) ap Gwyn (c. 950) ap Gruffudd (c. 915) ap Beli (c. 885) ap Selyf (c. 850) ap Brochwel (c. 820) ap Aeddan (c. 785).  The c. 980 Pasgen was the first of 4 men in the Powys Royal family to bear the same 7-generation string of names beginning with 4 different men called Brochwel ap Aeddan.  Dafydd and Dyddgu had a son:
 
             141.  Dafydd Wele ap Dafydd ap Madog Heddwch
 
Harl. 1977, 123 cites "Dafydd ap Madog Heddwch ap Meilyr" married "Dyddgu ferch Deio ap Madog ap Iorwerth Foel ap Ieuaf Sais" while Pen. 131,285 and Pen. 129, 53 extend her ancestry to "Iorwerth Foel ap Ieauf Sais ap Cyfnerth ap Iddon ap Trahaearn Tynhearn ap Iorwerth ap Mael".  While they insert "ap" before Tynhearn, the chronology requires Trahaearn to be a grandson of Mael.
 
Harl. 1973, 136 cites "Dafydd ap Madog Heddwch" as the father of Dafydd Wele
 
111.  Ithel ap Madog Heddwch ap Meilyr, born c. 1275
        His wife is unknown, but he had a son:
 
            142.  Llewelyn ap Ithel ap Madog Heddwch
 
Pen. 287, 509 cites "Ithel ap Madog Heddwch ap Meilyr" as the father of Llewelyn
 
112.  Madog ap Pyll ap Deheuwynt, born c. 1265
        His wife is unknown, but he had a son:
 
            143.  Einion ap Madog ap Pyll
 
Pen. 127, 129 cites "Madog ap Pyll ap Deheuwynt" as the father of Einion
 
113.  Gwyn ap Hywel ap Iorwerth, born c. 1260
        His wife is unknown, but he had a son:
 
           144.  Rhiryd Ddu ap Gwyn ap Hywel
 
Pen. 176, 84 & 93; Pen. 287, 510 cite "Gwyn ap Hywel ap Iorwerth" as the father of Rhiryd Ddu
 
114.  Gwgan ap Trahaearn ap Meilyr, born c. 1250
        His wife is unknown, but he had a son:
 
           145.  Meilyr ap Gwgan ap Trahaearn
 
Harl. 1973, 26 cites "Gwgan ap Trahaearn ap Meilyr" as the father of Meilyr
 
115.  Trahaearn Goch ap Iorwerth Fychan ap Iorwerth Y Gwion, born c. 1260
        He married Annes (c. 1270) ferch Ieuan (c. 1235) ap Madog (c. 1205) ap Einion (c. 1170) ap Cynfelyn of Maesmawr in Arwystli(c. 1140).  They had 3 sons:
 
           146.  Iorwerth ap Trahaearn Goch ap Iorwerth Fychan
           147.  Madog Lloyd ap Trahaearn Goch ap Iorwerth Fychan
 
PF 5, 120 cites "Agnes (Annes) ferch Ieuan ap Madog ap Einion ap Cynfelyn" married "Trahaeaern ap Iorwerth" but incorrectly identifies him as the earlier man of that name (#51 above).  Bartrum ignores the lady because she doesn't fit chronologically with a c. 1170 Trahaearn, but matches well with this Trahaearn Goch.
 
Montgomeryshire Collections vii, 55 also mistakes Trahaearn Goch for the earlier Trahaearn ap Iorwerth.
 
Hist. Llangurig, pp 370 also cites this marriage
 
116.  Ieuan Goch ap Iorwerth Fychan ap Iorwerth Y Gwion, born c. 1260
        His wife is unknown, but he had a son:
 
           148.  Ieuan Dwy ap Ieuan Goch ap Iorwerth Fychan
 
Dwnn i, 21 cites Ieuan Dwy as a son of Ieuan Goch, but simply calls the father of Ieuan Goch "Iorwerth".  Chronologically, only Iorwerth Fychan fits.
 
117.  Rhys ap Iorwerth Fychan ap Iorwerth Y Gwion, born c. 1265
        He resided in Mochdre in Ceri after marrying a lady from there.  His wife was Sian (c. 1280) ferch Einion Hen (c. 1252) ap Madog (c. 1224) ap Maredudd (c. 1196) ap Maelgwn II (c. 1168) ap Maelgwn (c. 1138) ap Cadwallon (c. 1110) ap Madog (c. 1080) ap Idnerth (c. 1050) ap Cadwgan (c. 1020) ap Elystan Glodrydd (c. 990).  Rhys and Sian had 2 sons:
 
              149.  Dafydd ap Rhys ap Iorwerth Fychan
              150.  Llewelyn ap Rhys ap Iorwerth Fychan
 
Dwnn i, 111 calls Rhys the son of Iorwerth ap Trahaearn ap Iorwerth.  Dwnn 1, 21 makes the same error with his brother, Ieuan Goch.  Both the family timeline, and that of the ladies connected by marriage, point to a birthdate of 1260/65 for the two brothers; we believe their father was Iorwerth Fychan ap Iorwerth. 
 
Vis. Shropshire of 1623, pp 476 says Rhys married "Jonetta filia Einani Penn de Morcheir" while Dwnn 1, 111 calls his wife "Sian v Einion Penn Esq".  Bartrum agrees that she was "of Mochdre" in Ceri, the seat of the family descended from Elystan Glodrydd.  We think Einion Hen was corrupted to Einion Pen and then Einion Penn.
 
Pen. 128, 192 and Pen. 133, 208 cite the Mochdre family as "Madog ap Maredudd ap Maelgwn ap Cadwallon ap Madog ap Idnerth", a construction 1 generation deficient to reach Madog ap Maredudd.  Pen 137, 182 cites a Maelgwn ap Maelgwn ap Cadwallon, and we established he was the father of Maredudd with our work on the Ceri family.  Our making Einion Hen a son of Madog ap Maredudd is consistent with the timeline and with his cited home at Mochdre.
 
118.  Ieuan Fychan ap Iorwerth Fychan ap Iorwerth Y Gwion, born c. 1265
        He married Alison (c. 1270) ferch Rhiwallon Fychan (c. 1235) ap Rhiwallon Lloyd (c. 1205) ap Ithel (c. 1175) ap Rhys (c. 1140) ap Ifor (c. 1105) ap Hywel (c. 1070) ap Morgan Fychan (c. 1040) ap Morgan Hir (c. 1010) of Gwent.  They had a son:
 
              151.  Madog ap Ieuan Fychan ap Iorwerth Fychan
 
Harl. 1973, 119 cites "Ieuan ap Iorwerth[Fychan] ap [Iorwerth y] Gwion" married "Alison ferch Rhiwallon Fychan ap Rhiwallon Lloyd" while Pen. 131, 286 extends that to "Rhiwallon Fychan ap Rhiwallon Lloyd ap Ithel ap Rhys ap Ifor ap Hywel ap Morgan Fychan of Ewias ap Morgan Hir of Gwent".  Morgan Hir is mistaken for a son of Iestyn ap Gwrgan, but that is impossible; he might be a brother of Gwrgan ap Ithel Ddu.  Harl. 1973, 119 cites this Ieuan as the father of Madog.  We made him "Ieuan Fychan" because we believe he had an older brother called Ieuan Goch
 
119.  Llywarch ap Llewelyn ap Ithel Dalfrith, born c. 1260
        His wife is unknown, but he had a son:
 
              152.  Einion ap Llywarch ap Llewelyn
 
Pen. 127, 137; Pen. 176, 123: Pen. 176, 221 cite "Llywarch ap Llewelyn ap Ithel Dalfrith" as the father of Einion
 
120.  Einion ap Llewelyn ap Ithel Dalfrith, born c. 1265
        His wife is unknown, but he had a son:
 
              153.  Gronwy Sais ap Einion ap Llewelyn
 
Pen. 129, 111; Pen 127, 133; Pen 128, 156a & 212a cite "Einion ap Llewelyn ap Ithel Talfrith" as the father of Gronwy Sais.
 
This is NOT the same man as "Einion ap Llywarch ap Llewelyn ap Ithel Talfrith" who  also had a son named Gronwy Sais that is cited in Pen 127, 136; Pen, 176, 123 & 221.  He is #152 below
 
121.  Iorwerth ap Gruffudd ap Maredudd, born c. 1275
        His wife is unknown, but he had a son:
 
              154.  Dafydd ap Iorwerth ap Gruffudd
 
Pen. 287, 423 cites the heiress of Garthmyl as having descended from Dafydd ap Iorwerth
 
122.  Philip ap Ithel ap Llewelyn, born c. 1255
        His wife is unknown, but he had a son:
 
              155.  Rhys ap Philip ap Ithel
 
Pen. 176, 362 and Pen. 177, 45 cite "Philip ap Ithel ap Llewelyn" as the father of Rhys
         
GENERATION 14:
 
123.  Cadwgan Ddu ap Cadwgan Goch ap Cadwgan y Gwion, born c. 1280
        He married Mali (c. 1295) ferch Sir Gruffudd Lloyd (c. 1260) ap Sir Rhys (c. 1230) ap Gruffudd (c. 1195) ap Ednyfed Fychan (c. 1165). They had 4 sons:
 
              156.  Madog ap Cadwgan Ddu ap Cadwgan Goch
              157.  Einion ap Cadwgan Ddu ap Cadwgan Goch
              158.  Dafydd Goch ap Cadwgan Ddu ap Cadwgan Goch
              159.  Iorwerth ap Cadwgan Ddu ap Cadwgan Goch
 
PF ii, 350 (citing the Golden Grove Ms) says "Cadwgan Ddu ap Cadwgan Goch ap Gwion" married "Mali ferch Sir Gruffudd Lloyd ap Sir Rhys ap Gruffudd ap Ednyfed Fychan".
 
Pen. 128, 148c cites "Cadwgan Ddu ap Cadwgan Goch" as the father of Madog
 
Pen. 128, 617b cites "Cadwgan Ddu ap Cadwgan Goch" as the father of Einion
 
PF ii, 350 cites "Cadwgan Ddu ap Cadwgan Goch" as the father of Dafydd Goch, while Pen. 287, 504 incorrectly makes Dafydd Goch the son of Iorwerth ap Cadwgan Ddu.
 
Pen. 129, 111 cites "Cadwgan Ddu ap Cadwgan Goch" as the father of Iorwerth
 
124.  Madog ap Cadwgan Frych ap Cadwgan y Gwion, born c. 1285
        His wife is unknown, but he had a son:
 
              160.  Cynwrig ap Madog ap Cadwgan Frych
 
Pen. 128, 906a cites "Madog ap Cadwgan Frych" as the father of Cynwrig
 
125.  Madog ap Ithel ap Jonas, born c. 1290
        His wife is unknown, but he had a son:
 
              Maredudd ap Madog ap Ithel, born c. 1320 who had a daughter:
                     Susanna ferch Maredudd ap Madog, born c. 1350.  She married Tudor (c. 1335) ap Hywel (c. 1305) ap Cynwrig Fychan (c. 1270) ap Cynwrig (c. 1240) ap Llywarch (c. 1205) ap Heilyn Gloff (c. 1175) ap Tyfid (c. 1145) ap Tangno (c. 1110) ap Ystrwyth (c. 1080) ap Marchwystl (c. 1050) ap Marchweithian (c. 1020), Lord if Is Aled.
 
Dwnn ii, 228 cites "Susanna ferch Maredudd ap Madog ap Ithel ap Jonas" married "Tudor ap Hywel ap Cynwrig Fychan ap Cynwrig ap Llywarch ap Heilyn ap Tyfid ap Tangno ap Ystrwyth ap Marchwystl ap Marchweithian"
 
126.  Maredudd ap Madog ap Jonas, born c. 1290
        His wife is unknown, but he had a son:
 
            161.  Einion ap Maredudd ap Madog
 
Pen. 128, 216a cites "Maredudd ap Madog ap Jonas" as the father of Einion
 
127.  Llywarch ap Iorwerth ap Llewelyn, born c. 1280
        His wife is unknown, but he had a son:
 
            162.  Cynwrig ap Llywarch ap Iorwerth
 
Pen. 136, 77 cites "Llywarch ap Iorwerth ap Llewelyn" as the father of Cynwrig
 
128.  Madog Goch ap Owain Fychan ap Owain Wynn, born c. 1290
        His wife is unknown, but he had a son:
 
            163.  Madog ap Madog Goch ap Owain Fychan
 
Dwnn ii, 300 cites "Madog Goch ap Owain Fychan ap Owain Wynn" as the father of Madog
 
129.  Dafydd ap Rhys Lloyd ap Owain Wynn, born c. 1295
        His wife is unknown, but he had a son:
 
              Dafydd Wynn ap Dafydd ap Rhys Lloyd, born c. 1325.  He married Myfanwy (c. 1345) ferch Dafydd Lloyd (c.) ap Dafydd (c.) ap Einion (c.) ap Ednyfed (c. 1220) ap Sulien (c. 1190) ap Caradog (c. 1155) ap Collwyn (c. 1120) ap Y Llawer Craff (c. 1090) ap Maredudd (c. 1055) ap Cynan (c. 1014) and had a daughter:
                     Angharad ferch Dafydd Wynn ap Dafydd, born c. 1360. She married Dafydd (c.1345) ap Owain (c. 1310) ap Rhys Goch (c. 1280) ap Rhys (c. 1250), Lord of Marton in Chirbury, Salop.
 
Dwnn i, 291 cites "Dafydd Wynn ap Dafydd ap Rhys Lloyd" married "Myfanwy ferch Dafydd ap Einion ap Ednyfed ap Sulien", while Pen. 131, 285 extends that as "Ednyfed ap Sulien ap Caradog ap Collwyn ap Llawr Grach ap Maredudd ap Cynan". Either Myfanwy was a daughter of Dafydd Lloyd ap Dafydd ap Einion ap Ednyfed or the marriage belongs to Dafydd the father of Dafydd Wynn.
 
Dwnn i, 291 also cites "Angharad ferch Dafydd Wynn ap Dafydd ap Rhys Lloyd" married "Dafydd ap Owain ap Rhys Goch ap Rhys, Lord of Marton".  We suspect the father of that Rhys was Cadwaladr ap Iorwerth ap Rhys Gwnley ap Rhys Fychan ap Dafydd ap Gruffudd Chwith, and that Gruffudd Chwith was a younger son of Cadwgan ap Elystan Glodrydd.  Bartrum's charts suggest, but do not make, both those connections
 
130.  Gronwy ap Cynwrig ap Iorwerth, born c. 1285
        He married Angharad (c. 1300) ferch Hywel (c. 1270) ap Dafydd (c. 1235) ap Gruffudd (c. 1205) ap Caradog (c. 1170) ap Thomas (c. 1135).  We suggest this Thomas was a son of Henry ap Cadwgan ap Bleddyn.
 
               164.  Gronwy Gethyn ap Gronwy ap Cynwrig
               165.  Madog ap Gronwy ap Cynwrig
 
Pen. 128, 147b, 272b & 590a cite "Angharad ferch Hywel ap Dafydd ap Gruffudd ap Caradog" married "Gronwy ap Cynwrig ap Iorwerth".  Dwnn ii, 69 extends her ancestry to "Gruffudd ap Caradog ap Thomas.
 
131.  Hwfa ap Heilyn Fychan ap Heilyn, born c. 1280

               172.  Einion ap Cadwgan ap Gwilym
 
Pen. 176, 48 and Pen 139(2), 216 cite "Cadwgan ap Gwilym ap Ithel" as the father of Einion
 
138.  Deio ap Iolyn ap Llewelyn, born c. 1295
        His wife is unknown, but he had a son:
 
               173.  Gruffudd ap Deio ap Iolyn
 
Pen. 287, 500 and Pen 139(1). 87 cite "Deio ap Iolyn ap Llewelyn" as the father of Gruffudd
 
139.  Einion ap Hywel ap Hwfa, born c. 1295
        His wife is unknown, but he had a son:
 
               174.  Madog ap Einion ap Hywel
 
Pen. 177, 45 cites "Einion ap Hywel ap Hwfa" as the father of Madog, but omits 4 generations by skipping to Hwfa ap Ithel Felyn.
 
Pen. 134, 367 and Pen 128, 605a make the same omission, but append "Foel" to the later Hywel. 
 
The only construction which works chronologically is "Madog ap Einion ap Hywel ap Hwfa ap Madog ap Einion ap Hywel Foel ap Hwfa ap Ithel Felyn"
 
140.  Rhiwallon ap Meilyr ap Madog Goch, born c. 1300
        His wife is unknown, but he had a son:
 
               175.  Hywel Goch ap Rhiwallon ap Meilyr
 
Harl. 1977, 123v cites "Hywel Goch ap Rhiwallon ap Meilyr" but skips 2 generations by making Meilyr the son of Tangwel.  See notes at #83
 
141.  Dafydd Welw ap Dafydd ap Madog Heddwch, born c. 1300
        He married Mallt (c. 1315) ferch Dafydd (c. 1280) ap Rhiryd (c. 1245) ap Trahaearn (c. 1215) ap Pasgen (c. 1180) ap Gwyn (c. 1150) ap Gruffudd (c. 1115) ap Beli (c. 1080) ap Selyf III (c. 1040) ap Brochwel III (c. 1005) ap Aeddan III (c. 975) ap Selyf II (c. 945) Ap Brochwel II (c. 910) ap Aeddan II (c. 880) ap Selyf I (c. 850) ap Brochwel I (c. 820) ap Aeddan I (c. 785) ap Cyngen (c. 750) ap Brochwel (c. 715) ap Eliseg (c. 685) ap Gwylog (c. 655) descended from Cadell Ddyrnllwg.  They had 2 sons:
 
              176.  Dafydd Lloyd ap Dafydd Welw ap Dafydd
              177.  Dafydd Fain ap Dafydd Welw ap Dafydd
 
Harl. 1973, 136 cites "Dafydd Wele ap Dafydd ap Madog Heddwch" married "Mallt ferch Dafydd ap Rhiryd" while Pen. 127, 148 extends her ancestry as "Rhiryd ap Trahaearn ap Pasgen ap Gwyn" and Pen. 131, 138 continues as "Pasgen ap Gwyn ap Gruffudd".
 
Harl. 1973, 136 cites Dafydd Wele and Mallt as the parents of Dafydd Fain
 
Dwnn i, 322 cites "Dafydd Wele ap Dafydd" as the father of Dafydd Lloyd

142.  Llewelyn ap Ithel ap Madog Heddwch, born c. 1295
        His wife is unknown, but he had a son:
 
               Gruffudd ap Llewelyn ap Ithel, born c. 1330.  He had a son
                       John ap Gruffudd ap Llewelyn, born c. 1360.  His son
                                Ieuan ap John ap Gruffudd was born c. 1390
 
Pen. 287, 509 cites "Ieuan ap John ap Gruffudd ap Llewelyn ap Ithel ap Madog Heddwch ap Meilyr"
 
143.  Einion ap Madog ap Pyll, born c. 1300
        His wife is unknown, but he had a son:
 
               178.  Maredudd ap Einion ap Madog
 
Pen. 127, 129 cites "Einion ap Madog ap Pyll" as the father of Maredudd
 
144.  Rhiryd Ddu ap Gwyn ap Hywel, born c. 1290
        His wife is unknown, but he had 3 sons:
 
               179.  Dafydd ap Rhiryd Ddu ap Gwyn
               180.  Madog ap Rhiryd Ddu ap Gwyn
                       Llewelyn ap Rhiryd Ddu ap Gwyn, born c. 1325, had a daughter:
                               Alison ferch Llewelyn ap Rhiryd Ddu, born c. 1360.  She married Belyn (c. 1350) ap Madog (c. 1320) ap Llewelyn Foel (c. 1290) ap Llewelyn (c. 1260) ap Madog (c. 1230) ap Llewelyn (c. 1195) ap Ithel (c. 1165) ap Heilyn (c. 1135) ap Eunydd (c. 1105) ap Heilyn (c. 1075) ap Eunydd (c. 1045) of Dyffryn Clwyd
 
Pen. 176, 93 and Pen 287, 510 cite "Rhiryd Ddu ap Gwyn ap Hywel" as the father of Dafydd
 
Pen. 176, 84 cites "Rhiryd Ddu ap Gwyn ap Hywel" as the father of Madog
 
Harl. 1969, 447/448 cites "Alison ferch Llewelyn ap Rhiryd ap Gwyn" married "Belyn ap Madog ap Llelo"; Harl. 1972, 78 says Llelo is aka Llewelyn Foel and cites "Llewelyn Foel ap Llewelyn ap Madog ap Llewelyn ap Ithel ap Heilyn ap Eunydd".  Chronologically, this is Heilyn ap Eunydd ap Heilyn ap Eunydd ap Morien of Dyffryn Clwyd
 
145.  Meilyr ap Gwgan ap Trahaearn, born c. 1280
        His wife is unknown, but he had a son:
 
              181.  Maredudd ap Meilyr ap Gwgan
 
Harl. 1973, 26 cites "Meilyr ap Gwgan ap Trahaearn" as the father of Maredudd
 
146.  Iorwerth ap Trahaearn Goch ap Iorwerth Fychan, born c. 1290
        He married Elen (c. 1300) ferch Madog Fychan (c. 1270) ap Madog (c. 1240) ap Eginyr (c. 1210) ap Einion (c. 1180) ap Madog (c. 1150) ap Gwylog (c. 1120) descended from Idnerth Benfras. They had 5 sons:
 
              182.  Iorwerth Fychan ap Iorwerth ap Trahaearn Goch
              183.  Ieuan ap Iorwerth ap Trahaearn Goch
              184.  Jonas ap Iorwerth ap Trahaearn Goch
              185.  Trahaearn ap Iorwerth ap Trahaearn Goch
                      Hywel ap Iorwerth ap Trahaearn Goch, born c. 1320, had a daughter:
                             Efa ferch Hywel ap Iorwerth, born c. 1350.  She married first, Maredudd (c. 1335) ap Madog (c. 1300) ap Ieuan (c. 1265) ap Iorwerth Fychan (c. 1230).  See #189 below.  She married secondly, Llewelyn (c. 1335) ap Maredudd (c. 1305) ap Madog (c. 1275) ap Iorwerth (c. 1245) ap Maredudd (c. 1210) ap Madog Danwr (c. 1175) descended from Tudor Trevor.
 
Hist. Langurig, pp 370 says "Iorwerth ap Trahaearn of Garthmyl" married "Elen ferch Madog Fychan".  Our extension of Madog Fychan back to Idnerth Benfras is based on our construction of that family, whose cited pedigrees are all flawed.
 
Dwnn i, 308 cites "Iorwerth Fychan ap Iorwerth ap Trahaearn" and assigns that Iorwerth Fychan a wife born c. 1335; this cannot be the Iorwerth Fychan ap Iorwerth ap Trahaearn from #88 above, so we believe this was Trahaearn Goch's family.
 
Harl. 1973, 26 cites "Iorwerth Fychan ap Iorwerth ap Trahaearn" as the father of Ieuan, assigning Ieuan a wife born c. 1365.  Accordingly, we believe this was Trahaearn Goch's family, not the earlier Trahaearn of Garthmyl.
 
PF ii, 347 cites "Iorwerth Fychan ap Iorwerth ap Trahaearn" as the father of Jonas.  For the reasons stated immediately above, we think this was Trahaearn Goch
 
See comments at #185 for Trahaearn ap Iorwerth ap Trahaearn Goch
 
PF v, 120/121 says "Efa ferch Hywel ap Iorwerth ap Trahaearn" married "Maredudd ap Madog ap Ieuan ap Iorwerth Fychan ap (Iorwerth) Y Gwion ap Trahaearn, while Dwnn i, 311 makes her the mother of "Ieuan ap Maredudd ap Madog".  The last source errs in its ancestry of Maredudd ap Madog, perhaps due to confusion with her second husband.
 
PF ii, 202 says "Efa ferch Hywel ap Iorwerth ap Trahaearn" married "Llewelyn ap Iorwerth ap Maredudd ap Madog Danwr, a construction with 2 missing generations.  Pen. 128, 721b calls her second husband "Llewelyn ap Maredudd ap Madog Danwr", a construction with 3 missing generations.  Dwnn i, 311 cites a "Maredudd ap Madog ap Iorwerth ap Maredudd ap Madog Danwr" and we believe he was the father of Efa's husband, Llewelyn.  The Pen. 128 citation equates the Madog who was the grandfather of Llewelyn with Madog Danwr of 100 years earlier.
 
We believe Efa was "ferch Hywel ap Iorwerth ap Trahaearn Goch" and was born c. 1350 because her son, Ieuan, married a lady born c. 1375.
 
147.  Madog Lloyd ap Trahaearn Goch ap Iorwerth Fychan, born c. 1295
        He resided at Garth Acres and married Annes (c. 1310) ap Llewelyn (c. 1280) ap Einion (c. 1250) ap Celynin (c. 1220) ap Rhiryd (c. 1190) ap Cynddelw (c. 1155) ap Iotrwerth (c. 1125) ap Gwrgeneu (c. 1095) ap Uchdryd (c. 1060) ap Aleth (c. 1025) ap Iorwerth (c. 995) ap Uchdryd (c. 965) ap Aleth (c. 930) ap Alser (c. 895) ap Tudwal Gloff (c. 865) ap Rhodri Mawr (c. 820).  They had a son:
 
              186.  Ieuan ap Madog Lloyd ap Trahaearn Goch
 
Dwnn i, 308 cites a Madog Lloyd of Garth Acres as father of Ieuan and as a descendant of Llewelyn Aurdorchog.  We believe this was a manor on the original lands of Garthmyl; his birthdate suggests he was in the 4th generation after Trahaearn ap Iorwerth of c. 1170 and Lewys Dwnn, assuming that was his father, did not bother to recite his ancestry.  We think he was a son of Trahaearn Goch ap Iorwerth Fychan.  This sources also names his wife as "Annes ferch Llewelyn ap Einion ap Celynin"
 
Pen. 127, 9; Pen. 176, 129; Pen. 135, 391 give the ancestry of Annes as "Llewelyn ap Einion ap Celynin ap Rhiryd ap Cynddelw ap Iorwerth ap Gwrgeneu ap Uchdryd ap Aleth".  Extending this ancestry back to Tudwal Gloff is merely our own construction based on our work on that family.
 
148.  Ieuan Dwy ap Ieuan Goch ap Iorwerth Fychan, born c. 1290
        His wife is unknown, but he had a son:
 
              187.  Ieuan Fychan ap Ieuan Dwy ap Ieuan Goch
 
Dwnn i, 21 cites "Ieuan Dwy ap Ieuan Goch" as the father of Ieuan Fychan
 
149.  Dafydd ap Rhys ap Iorwerth Fychan, born c. 1295
        He lived at Betws in Ceri and married Jane (c. 1310), daughter of Sir John of Walcot in Salop (c. 1285).  They moved to Walcot after the death of Jane's father and had a son:
 
              188.  Evan Walcot ap Dafydd ap Rhys
 
Dwnn i, 111; Visitation of Shropshire, 476 cite "Dafydd ap Rhys as Iorwerth" married "Jane, daughter of Sir John of Walcot".  The timeline suggests the father of Dafydd and his brother, Llewelyn, was actually Iorwerth Fychan.  Both sources say Dafydd ap Rhys was the father of Evan de Walcot.
 
150.  Llewelyn ap Rhys ap Iorwerth Fychan, born c. 1300
        His wife is unknown, but he had a son:
 
                Ieuan ap Llewelyn ap Rhys, born c. 1330.  His daughter:
                       Ales ferch Ieuan ap Llewelyn, born c. 1370, married Ieuan (c. 1360) ap Maredudd (c. 1325) ap Gruffudd Fychan (c. 1295) ap Gruffudd Foel (c. 1265) ap Gruffudd (c. 1235) ap Llewelyn (c. 1205) ap Maredudd Bengoch (c. 1170) ap Llewelyn Fraisg (c. 1140) ap Hywel (c. 1110) ap Seisyll (c. 1080) ap Llewelyn (c. 1050) ap Cadwgan (c. 1020) ap Elystan Glordydd (c. 985) Prince of Fferlys.
 
Harl. 1972, 122 cites "Alis ferch Ieuan ap Llewelyn ap Rhys ap Iorwerth" married "Ieuan ap Maredudd ap Gruffudd Fychan ap Gruffudd Foel ap Gruffudd ap Llewelyn ap Maredudd ap Llewelyn Goch ap Llewelyn Fraisg".  Our work on that family suggests Llewelyn Goch and Llewelyn Fraisg were brothers who both had sons named Maredudd, one nicknamed 'Bengoch' and the other 'Hen'.  Pen. 127, 103 cites "Llewelyn ap Hywel ap Seisyllt ap Llewelyn", while JC Ms 20, 32 cites "Seisyllt ap Llewelyn ap Cadwgan ap Elystan".
 
151.  Madog ap Ieuan Fychan ap Iorwerth Fychan, born c. 1300
        He married Elen ferch Adda, whose ancestry is unknown.  They had a son:
 
             189.  Maredudd ap Madog ap Ieuan
 
Harl. 1973, 119 cites "Madog ap Ieuan ap Iorwerth" as the father of Maredudd.  Refer to the entries for his father and grandfather for our reasons to append "Fychan" to their names.
 
152.  Einion ap Llywarch ap Llewelyn, born c. 1290
        His wife is unknown, but he had 3 sons:
 
             190.  Gronwy Sais ap Einion ap Llywarch
             191.  Llewelyn Sais ap Einion ap Llywarch
                     Gwyn Hagr ap Einion ap Llywarch, born c. 1325.  He married a daughter (c. 1335) ferch Gronwy Lloyd (c. 1300) ap Iorwerth y Penwyn (c. 1270) ap Cynwrig (c. 1240) ap Iorwerth (c. 1205) ap Tegwared (c. 1170) ap Iddon (c. 1135) ap Iorwerth (c. 1100) ap Iddon (c. 1070) ap Ithel (c. 1035) ap Edred (c. 1005) descended from Marchudd ap Cynan.
 
Pen. 129, 111; Pen. 176, 123 & 221 cite "Einion ap Llywarch ap Llewelyn" as the father of Gronwy Sais
 
Pen. 135, 265 cites Gwyn Hagr as a son of "Einion ap Llewelyn".  Pen. 131, 24 cites a "Gwyn ap Einion" without naming Einion's father, and says he married "a daughter of Gronwy Lloyd ap y Penwyn".  Pen. 127, 59 continues "Y Penwyn ap Cynwrig ap Iorwerth ap Tegwared ap Iddon"  The timeline of that family dates the lady c. 1335, so Gwyn Hagr must be a grandson of Llewelyn ap Ithel Dalfrith, i.e. "ap Einion ap Llywarch ap Llewelyn".  Later pedigrees confuse two lines descended from Llewelyn ap Ithel Dalfrith because there was both a "Gronwy Sais ap Einion ap Llewelyn" and a Gronwy Sais ap Einion ap Llywarch ap Llewelyn".
 
The sources for Llewelyn Sais ap Einion will be discussed in #191 below
 
153.  Gronwy Sais ap Einion ap Llewelyn, born c. 1295
        His wife is unknown, but he had a son:
 
          192.  Deicws ap Gronwy Sais ap Einion
 
Pen. 129, 111; Pen. 127, 133; Pen 128, 156a & 612a: cite "Gronwy Sais ap Einion ap Llewelyn"
 
Harl. 1969, 214 cites "Deicws ap Gronwy Sais ap Einion"
 
154.  Dafydd ap Iorwerth ap Gruffudd, born c. 1305
        His wife is unknown, but he had a son:
 
           193.  Ieuan ap Dafydd ap Iorwerth

Pen. 287, 423 cites "Ieuan ap Dafydd ap Iorwerth" in the chain of holders of the manor at Garthmyl
 
155.  Rhys ap Philip ap Ithel, born c. 1290
        His wife is unknown, but he had 2 sons:
 
             194.  Gronwy Ddu ap Rhys ap Philip
             195.  Tudor ap Rhys ap Philip
 
Pen. 177, 45 cites "Rhys ap Philip ap Ithel" as the father of Gronwy Ddu
 
Pen. 287, 507 cites "Rhys ap Philip" as the father of Tudor
 

GENERATION 15:
 
156.  Madog ap Cadwgan Ddu ap Cadwgan Goch, born c. 1310
        He married Marged (c. 1320) ferch Iorwerth (c. 1285) ap Dafydd Hen (c. 1250) ap Gronwy (c. 1215) ap Iorwerth (c. 1185) ap Hywel (c. 1155) ap Moreiddig (c. 1125) ap Sandde Hardd or Mortyn (c. 1095). They had a son:
 
         196.  Ieuan ap Madog ap Cadwgan Ddu
 
Pen. 128, 148 cites "Madog ap Cadwgan Ddu ap Cadwgan Goch" married "Marged ferch Iorwerth ap Dafydd" while Pen. 129, 55 extends her ancestry to "Iorwerth ap Dafydd ap Grronwy ap Iorwerth ap Hywel ap Moreiddig ap Sandde Hardd".  The first citation makes Ieuan their son.
 
157.  Einion ap Cadwgan Ddu ap Cadwgan Goch, born c. 1310.
        His wife is unknown, but he had a son:
 
         197.  Einion Fychan ap Einion ap Cadwgan Ddu
 
Pen. 128, 617b cites "Einion ap Cadwgan Ddu" as the father of Einion Fychan
 
158.  Dafydd Goch ap Cadwgan Ddu ap Cadwgan Goch, born c. 1315
        His wife is unknown, but he had a son:
 
         198.  Dafydd ap Dafydd Goch ap Cadwgan Ddu
 
Pen. 287, 504 cites "Dafydd Goch ap Iorwerth ap Cadwgan Ddu" as the father of Dafydd, but that construction is a generation too long.  We think Dafydd Goch was a brother of Iorwerth ap Cadwgan Ddu, as given in PF ii, 350
 
159.  Iorwerth ap Cadwgan Ddu ap Cadwgan Goch, born c. 1315
        His wife is unknown, but he had a son:
 
          199.  Cadwgan Decca ap Cadwgan Ddu ap Cadwgan Goch
 
Pen. 128, 612a cites "Iorwerth ap Cadwgan Ddu" as the father of Cadwgan Decca.  Pen. 129, 111 and Pen 127, 132 cite the same, but omit the nickname "Decca"
 
160.  Cynwrig ap Madog ap Cadwgan Frych, born c. 1315
        His wife is unknown, but he had a son:
 
          200.  Hywel ap Cynwrig ap Madog
 
Pen. 128, 906a cites "Cynwrig ap Madog ap Cadwgan Frych" as the father of Hywel
 
161.  Einion ap Maredudd ap Madog, born c. 1320
        His wife is unknown, but he had a son:
 
          201.  Dafydd ap Einion ap Maredudd
 
Pen. 128, 216a cites "Einion ap Maredudd ap Madog" as the father of Dafydd
 
162.  Cynwrig ap Llywarch ap Iorwerth, born c. 1310
        His wife is unknown, but he had a son:
 
          202.  Iolyn ap Cynwrig ap Llywarch
 
Pen. 136, 77 cites "Cynwrig ap Llywarch ap Iorwerth" as the father of Iolyn
 
163.  Madog ap Madog Goch ap Owain Fychan, born c. 1325
        His wife is unknown, but he had a son:
 
         203.  Bleddyn ap Madog ap Madog Goch
 
Dwnn ii, 300 cites "Madog ap Madog Goch ap Owain Fychan" as the father of Bleddyn.  It dates Madog as "amser (in the time of) Edward I" but we believe it was his father who was born during the reign of Edward I; Madog ap Madog Goch appears to have been born "amser Edward II"
 
164.  Gronwy Gethyn ap Gronwy ap Cynwrig, born c. 1320
        His wife is unknown, but he had 2 sons and a daughter:
 
         204.  Gronwy Ddu ap Gronwy Gethyn ap Gronwy
                 Iolyn ap Gronwy Gethyn ap Gronwy, born c. 1355.  His wife is unknown, but he had a daughter:
                        Cathryn ferch Iolyn ap Gronwy Gethyn, born c. 1390. She married Rhys (c. 1380) ap Ithel (c. 1345) ap Gruffudd (c. 1315) ap Ithel Goch (c. 1280) ap Cynwrig (c. 1245) ap Iorwerth (c. 1215) ap Cynwrig Ddewis Herod (c. 1185) ap Cowryd Perfarch(c. 1150) ap Iarddur (c. 1115) ap Llewelyn Meudwy (c. 1085) ap Hedd (c.1050).  The latter was a founder of one of the 15 Noble Tribes of North Wales.
                Annesta ferch Gronwy Gethyn ap Gronwy, born c. 1350, married Ieuaf (c. 1340) ap Hwfa (c. 1310) ap Madog yr Athro (c. 1280) ap Hwfa (c. 1250) ap Iorwerth (c. 1220) ap Gruffudd (c. 1190) ap Iorwerth (c. 1160) ap Ieuaf (c. 1130) ap Ninniaw (c. 1095) ap Cynwrig (c. 1065) ap Rhiwallon (c. 1030) ap Cynwrig (c. 995) ap Rhiwallon (c. 965) ap Dyngad (c. 930) ap Tudor Trevor (c. 900)
 
Pen. 132, 191 cites "Gronwy Gethyn ap Gronwy ap Cynwrig" as the father of Gronwy Ddu
 
Pen. 131, 53/54 cites "Cathryn ferch Iolyn ap Gronwy Gethyn and Gronwy" married "Rhys ap Ithel ap Gruffudd ap Ithel Goch ap Cynwrig ap Iorwerth ap Cynwrig Ddewis Herod ap Cowryd ap Perfarch ap Iarddur ap Llewelyn ap Meuter Fawr ap Hedd".  This list contains 2 more generations than the timeline allows and our work suggests Cowryd was nicknamed "Perfarch" and the "ap" following his name should be deleted; also we find that Llewelyn was nicknamed "Meudwy" which was corrupted into "Meuter Fawr", and believe Llewelyn was a son of Hedd. 
 
Pen. 128, 147b & 166a cite "Annes ferch Gronwy ap Cynwrig" but the timeline requires that she be a daughter of Gronwy Gethyn ap Gronwy ap Cynwrig.  The citations continue to say she married "Ieuan ap Hwfa ap Madog yr Athro".  Harl. 4181 calls him Ieuaf ap Hwfa ap Madog yr Athro, a construction we would accept since the male name Ieuaf was favored by that family.  Pen. 128, 137b continues "Madog yr Athro ap Hwfa ap Iorwerth ap Griffri ap Ieuaf ap Ninniaw" but confuses him with another Madog yr Athro (born c. 1330) ap Hwfa ap Hywel ap Hwfa ap Iorwerth ap Gruffudd ap Ieuaf ap Ninniaw.  The Madog yr Athro of c. 1280 descended from a Gruffudd ap Iorwerth ap Ieuaf ap Ninniaw.  See #204 below for another lady misidentified as Annes ferch Gronwy ap Cynwrig.
 
165.  Madog ap Gronwy ap Cynwrig, born c. 1315
        He married Alice, daughter of Roger Brereton, an Englishman from Cheshire.  They had a son:
 
            205.  Ieuaf ap Madog ap Gronwy
 
Pen. 131, 52; Pen. 129, 84; Pen. 127, 136 cite "Madog ap Gronwy ap Cynwrig" as the father of Ieuan
 
PF v, 91 (citing BM Add 9864) says "Madog ap Gronwy ap Cynwrig" married "Alice, d. of Roger Brereton of Cheshire"
 
166.  Dafydd Ddu ap Hwfa ap Heilyn Fychan, born c. 1315
        His wife is unknown, but he had a son:
 
            206.  Cynwrig ap Dafydd Ddu ap Hwfa
 
Pen. 176, 334 & Pen. 139(1), 82 cite "Dafydd Ddu ap Hwfa ap Heilyn Fychan" as the father of Cynwrig
 
167.  Gruffudd ap Iolyn ap Ieuan, born c. 1320
        His wife is unknown, but he had a son:
 
            207. Gwrgeneu ap Gruffudd ap Iolyn
 
Pen. 287, 506 cites "Gruffudd ap Iolyn ap Ieuan" as the father of Gwrgeneu

Pen. 177, 45 and Pen. 139(1), 82 cite "Ieuan ap Dai ap Madog ap Einion ap Hywel ap Hwfa", but the latter adds "Foel" to Hywel and both mistake Hwfa for the earlier Hwfa ap Ithel Felyn
 
Pen. 134, 367 cites "Deio ap Maredudd ap Madog ap Einion ap Hywel Foel at Hwfa", incorrectly adding "Foel" to Hywel and mistaking Hwfa for Hwfa ap Ithel Felyn
 
Pen. 128, 605a; Pen. 177, 178/179; Pen. 178 (1), 5 cite "Dafydd ap Ithel ap Madog ap Einion"
 
While there are no cited marriages to test the timeline in this branch of the family up to 1390, Bartrum agrees with the dating we suggest and indicates that it conforms to the families after 1400 where presumably he did find marriages to validate the timeline.  We do not ourselves have any post-1400 sources for the family. 
 
175.  Hywel Goch ap Rhiwallon ap Meilyr, born c. 1330
        His wife is unknown, but he had a son:

Harl. 1973, 136 cites "Dafydd Fain ap Dafydd Wele ap Dafydd" married "Nest ferch Madog ap Gruffudd" while Pen. 128, 850a extendeds her ancestry to "Madog ap Gruffudd ap Einion ap Ednyfed" and Pen. 131,285 continues "Einion ap Ednyfed ap Sulien ap Caradog ap Collwyn ap Llawr Grach ap Maredudd ap Cynan"
 
Dwnn i, 322 cites "Dafydd Fain ap Dafydd Wele" as the father of Madog Lloyd

182.  Iorwerth Fychan ap Iorwerth ap Trahaearn Goch, born c. 1320
        He married Lleuci (c. 1335) ferch Cadwgan (c. 1305) ap Philip Dorddu (c. 1270) ap Hywel (c. 1240) ap Madog (c. 1210) ap Hywel (c. 1180) ap Gruffudd (c. 1145) ap Gronwy (c. 1115) ap Gwrgeneu (c. 1085) ap Hoedliw (c. 1055) ap Cadwgan (c. 1020) ap Elystan Glodrydd (c. 990).  They had 3 sons:

Dwnn i, 308 cites "Iorwerth Fychan ap Iorwerth ap Trahaearn" married "Lleuci ferch Cadwgan ap Philip Dorddu", while Pen 133, 209 extends her ancestry to "Cadwgan ap Philip Dorddu ap Hywel ap Madog ap Hywel ap Gruffudd ap Gronwy" and Pen. 176, 127 continues as "Gruffudd ap Gronwy ap Gwrgeneu ap Hoedliw ap Cadwgan ap Elystan".  While Dwnn thought this Iorwerth Fychan ap Iorwerth ap Trahaearn was the same-named man of c. 1230, the timeline shows his grandfather was actually Trahaearn Goch.
 
Dwnn i, 308 cites "Iorwerth Fychan ap Iorwerth ap Trahaearn (Goch)" as the father of Madog y Twpa
 
PF ii, 347 (note 2) says "Iorwerth Fychan ap Iorwerth ap Trahaearn" was the father of Llewelyn
 
Harl. 1973, 26 cites "Iorwerth Fychan ap Iorwerth ap Trahaearn" as the father of Ieuan
 
183.  Ieuan ap Iorwerth ap Trahaearn Goch, born c. 1325
        His wife is unknown, but he had a son:
 
              Hywel ap Ieuan ap Iorwerth, born c. 1355, had two sons:
                    Dafydd ap Hywel ap Ieuan, born c. 1385
                    Morgan ap Hywel ap Ieuan, born c. 1390
 
Harl. 1973,29 cites Dafydd and Morgan as sons of Hywel ap Ieuan ap Iorwerth ap Trahaearn, omitting the "Goch" from Trahaearn.
 
184.  Jonas ap Iorwerth ap Trahaearn Goch, born c. 1325
        His wife is unknown, but he had a son:
 
            222.  Jonas Fychan ap Jonas ap Iorwerth
 
PF ii, 347 cites "Jonas ap Iorwerth ap Trahaearn" as father of Jonas Fychan.
 
185.  Trahaearn ap Iorwerth ap Trahaearn Goch, born c. 1330
        His wife is unknown, but he had 2 sons:

           224.  Einion ap Trahaearn ap Iorwerth
 
Harl. 1973, 28 cites Trahaearn ap Iorwerth as the father of Iorwerth
 
Harl. 1973, 21 cites Trahaearn ap Iorwerth as the father of Einion
 
The family timeline requires this to have been a Trahaearn ap Iorwerth born c. 1330, thus "ap Trahaearn Goch"
 
186.  Ieuan ap Madog Lloyd ap Trahaearn Goch. born c. 1330
        He married Sioned ferch Maredudd ap Madog ap Iorwerth Goch, whose ancestry is unknown.  They had 2 sons:
 
           225.  Maredudd ap Ieuan ap Madog Lloyd
           226.  Ieuan ap Ieuan ap Madog Lloyd
 
Dwnn i, 308 cites "Ieuan ap Madog Lloyd" married "Sioned ferch Maredudd ap Madog ap Iorwerth Goch"
 
187.  Ieuan Fychan ap Ieuan Dwy ap Ieuan Goch, born c. 1320
        His wife is unknown, but he had a son:
 
           227.  Dafydd ap Ieuan Fychan ap Ieuan Dwy
 
Dwnn i, 21 cites "Ieuan Fychan ap Ieuan Dwy ap Ieuan Goch" as the father of Dafydd
 
188.  Evan Walcot ap Dafydd ap Rhys, born c. 1325
        He married Anne (c. 1335) daughter of John Mynde (c. 1300) ap Simon Mynde (c. 1270) ap William Mynde of Shropshire (c. 1240) They had a son:
 
           228.  Roger Walcot of Walcot
 
Dwnn i, 111 and Vis of Shropshire, 476 cite "Evan Walcot ap Dafydd ap Rhys" married Anne, daughter of John Mynde", while Vis of Shropshire, 370 extends her ancestry to "John Mynde son of Simon Mynde.  Simon occurs in the same generation as Agnes Mynde who, in Dwnn i, 323, is cited as marrying William Mynde; we suggest Simon and Agnes were siblings. 
 
Both original citations mentioned above make Roger Walcot a son of Evan and Anne Mynde
 
189.  Maredudd ap Madog ap Ieuan, born c. 1335
        He married Efa (c. 1350) ferch Hywel (c. 1320) ap Iorwerth (c. 1290) ap Trahaearn Goch (c. 1260).  See #146 above.  They had a son:
 
          229.  Ieuan ap Maredudd ap Madog
 
Harl. 1973, 119 cites "Maredudd ap Madog ap Ieuan" married "Efa ferch Hywel ap Iorwerth ap Trahaearn" but only a granddaughter of Iorwerth ap Trahaearn Goch fits chronologically.  The same source cites their son, Ieuan.
 
190.  Gronwy Sais ap Einion ap Llywarch, born c. 1320
        His wife is unknown, but he had 4 sons and a daughter:
 
         230.  Owain ap Gronwy Sais ap Einion
         231.  Gruffudd ap Gronwy Sais ap Einion
         232.  Einion ap Gronwy Sais ap Einion
                 Dafydd ap Gronwy Sais ap Einion, born c. 1360.  He has a son:
                       Jenkin ap Dafydd ap Gronwy Sais, born c. 1395.  His daughter:
                             Gwenllian ferch Jenkin ap Dafydd, born c. 1430, married Ithel (c. 1425) ap Ieuan (c. 1395) ap Tudor (c. 1365)ap Llewelyn (c. 1330) ap Philip (c. 1300) ap Rhiryd (c. 1270) ap Ieuan (c. 1235) ap Elidyr (c. 1205) ap Garn (c. 1175) ap Yswatan Wyddel (c. 1140).  We believe Yswatan is a son of Iorwerth ap Aldud ap Owain ap Edwin of Tegeingl, and a brother of Ystifyn.
                 Cristyn ferch Gronwy Sais ap Einion, born c. 1350.  She married Gruffudd (c. 1335) ap Ieuan (c. 1305) ap Dafydd Ddu (c. 1270) ap Dafydd (c. 1240) ap Madog (c. 1210) ap Richard (c. 1175) ap Hywel (c. 1145) ap Llywarch (c. 1115) ap Rhiryd (c. 1080) ap Owain (c. 1050) ap Edwin of Tegeingl (c. 1020)
 
Pen. 127, 111 cites "Gronwy Sais ap Einion ap Llywarch"
 
Pen. 134, 116 cites "Gwenllian ferch Jenkin ap Dafydd ap Gronwy Sais ap Einion" married "Ithel ap Ieuan ap Tudor ap Llewelyn ap Philip ap Rhiryd ap Ieuan ap Elidyr ap Garn ap Yswatan Wyddel."  The family resided at Whitford Garn in Tegeingl, so the man called Garn may have an undisclosed birthname.
 
See #192 below for a Deicws ap Gronwy Sais who is often confused with this Dafydd ap Gronwy Sais.
 
191.  Llewelyn Sais ap Einion ap Llywarch, born c. 1320
        His wife is unknown, but he had 3 sons:
 
        233.  Madog Fychan ap Llewelyn Sais ap Einion
        234.  Gwyn ap Llewelyn Sais ap Einion
                Einion ap Llewelyn Sais ap Einion, born c. 1355
 
Pen. 135, 346 cites Madog Fychan as a son of Llewelyn Sais, but carries the ancestry no further.
 
B.M. Add. 15041, 322 cites "Llewelyn Sais ap Einion" as the father of Gwyn
 
Pen. 135, 345 cites "Llewelyn Sais ap Einion" as the father of Einion
 
192.  Deicws ap Gronwy Sais ap Einion, born c. 1330
        His wife is unknown, but he had a son:
 
         235.  Jenkin ap Deicws ap Gronwy Sais
 
Harl. 1969, 214 cites "Deicws ap Gronwy Sais ap Einion" as the father of Jenkin
 
Bartrum has confused this Deicws with a Dafydd ap Gronwy Sais ap Einion, who also named a son Jenkin, but the two men lived a whole generation apart.  See #190 above
 
193.  Ieuan ap Dafydd ap Iorwerth, born c. 1335
        His wife is unknown, but he had a son:
 
                  Ieuan Fwyndeg ap Ieuan ap Dafydd, born c. 1370.  He had a single daughter:
                         Marged ferch Ieuan Fwyndeg ap Ieuan, born c. 1400.  She married John (c. 1390) ap Hywel (c. 1360) ap Gruffudd Lloyd (c. 1330) ap Maredudd (c. 1295) ap Gruffudd Fychan (c. 1265) ap Gruffudd Ddu (c. 1235) ap Madog (c. 1205) ap Einion (c. 1170) ap Cynfelyn (c. 1140) of Maesmawr.  She carried the manor of Garthmyl to her husband and son and that family became known as Jones of Garthmyl
 
Pen. 287, 423 cites "Marged ferch Ieuan Fwyndeg ap Ieuan ap Dafydd ap Iorwerth" married John ap Hywel ap Gruffudd Lloyd ap Maredudd ap Gruffudd Fychan ap Gruffudd Ddu ap Madog ap Einion ap Cynfelyn"
 
Montgomeryshire Collections xxv, 297 cites the pedigree of the Jones Family, whose ancestor John ap Hywel ap Gruffudd Lloyd married the heiress of Garthmyl.  It calls her "Marged ferch Ieuan undeg, from Llewelyn Aurdorchog"
 
 
194.  Gronwy Ddu ap Rhys ap Philip, born c. 1320
        His wife is unknown, but he had a son:
 
            236.  Ieuan ap Gronwy Ddu and Rhys
 
Pen. 177,45 cites "Gronwy Ddu ap Rhys ap Philip" as the farther of Ieuan
 
 
195.  Tudor ap Rhys ap Philip, born c. 1325
        His wife is unknown, but he had a son:
 
           237.  Iolyn ap Tudor ap Rhys
 
Pen. 139(1), 82 and 128 cite "Tudor ap Rhys" as the father of Iolyn, while Pen. 287, 507 cites him as "Tudor ap Rhys ap Philip"
  
 
GENERATION 16:
 
196.  Ieuan ap Madog ap Cadwgan Ddu, born c. 1335
        He married Angharad (c. 1340) ferch Philip Kynaston (c. 1300) ap Gruffudd IV (c. 1265) ap Gruffudd III (c. 1230) ap Gruffudd Fychan (c. 1200) ap Sir Gruffudd (c. 1170) ap Iorwerth Goch (c. 1135) ap Maredudd (c. 1105) ap Bleddyn (c. 1075) ap Madog (c. 1045) ap Cadwgan of Rhos (c.1015).  They had a son and two daughters:
 
        238.  Madog ap Ieuan ap Madog
                Angharad ferch Ieuan ap Madog, born c. 1360.  She married first, Llewelyn Sais (c. 1345) ap Llewelyn (c. 1310) ap Madog (c. 1280) ap Einion (c. 1250) ap Madog (c. 1220) ap Bleddyn (c. 1190) ap Cynwrig (c. 1160) ap Rhiwallon (c. 1130) ap Ednyfed (c. 1100) ap Cynwrig (c. 1065) ap Rhiwallon (c. 1030) ap Cynwrig (c. 995) ap Rhiwallon (c. 965) ap Dyngad (c. 930) ap Tudor Trevor (c. 900).  She married secondly, Dafydd (Deio) (c. 1360) ap Madog Lloyd (c. 1330) ap Gruffudd (c. 1300) ap Iorwerth Foel (c. 1265) ap Iorwerth Fychan (c. 1235) ap Owain (c. 1205) ap Bleddyn (c. 1175) ap Tudor (c. 1145) ap Rhys Sais II (c. 1115) descended from Tudor Trevor.
                Marged ferch Ieuan ap Madog, born c. 1365.  She married Ieuan Bach (c. 1360) ap Ieuan (c. 1330) ap Einion Gethyn (c. 1300) ap Madog (c. 1265) ap Owain (c. 1235) ap Gruffudd (c. 1200) ap Cynwrig Fychan (c. 1165) ap Cynwrig Efell (c. 1135), a base son of Madog ap Maredudd ap Bleddyn ap Cynfyn.
 
PF ii, 351/352 (citing the Cae Cyriog Ms) says "Ieuan ap Madog ap Cadwgan Ddu" married "Angharad ap Philip Kynaston".  Pen. 128, 148a cites the same marriage and calls her "Angharad ap Philip ap Gruffudd".  Pen. 131, 127 extends the Kynaston pedigree ap "Philip ap Gruffudd ap Gruffudd Fychan ap Gruffudd ap Iorwerth Goch ap Maredudd" but that construction fails chronologically by a full generation.  We think Philip was the son of the 4th consecutive Gruffudd.
 
Pen. 128, 162a cites "Ieuan ap Madog ap Cadwgan Ddu" as the father of Madog
 
Pen. 128, 154a cites "Angharad ferch Ieuan ap Madog" married "Llewelyn Sais ap Llewelyn ap Madog ap Einion ap Madog ap Bleddyn ap Cynwrig ap Rhiwallon".  The Bleddyn in that family is called "of Bersham" so we would extend his pedigree to "Cynwrig ap Rhiwallon ap Ednyfed ap Cynwrig ap Rhiwallon" since this Ednyfed held Bersham.  The added generations are required for the chronology of this family.
 
Pen. 128, 147a/148a cites "Angharad ferch Ieuan ap Madog" married "Deio ap Madog Lloyd ap Iorwerth Foel", while Pen. 127, 21 extends his ancestry as "Madog Lloyd ap Iorwerth Foel ap Iorwerth Fychan ap Iorwerth Hen ap Owain ap Bleddyn ap Tudor ap Rhys Sais".  Our work on the chronology of this family suggests that Iorwerth Hen should be deleted from this list since he was probably the brother, not father of Iorwerth Fychan.  Both men married ladies born c. 1240 
 
Pen. 128, 162a cites "Marged ferch Ieuan ap Madog" married "Ieuan Bach ap Ieuan ap Einion Gethyn", while Pen. 128, 915 extends his ancestry as "Ieuan ap Einion Gethyn ap Madog ap Owain ap Gruffudd ap Cynwrig Efell".  Bartrum shows one generation missing from that construction; we believe Gruffudd was the son of Cynwrig Fychan ap Cynwrig Efell.  The wife usually cited for Cynwrig Efell was born c. 1160 and must have married a son of Cynwrig Efell, probably one also named Cynwrig.
 
 
197.  Einion Fychan ap Einion ap Cadwgan Ddu, born c. 1340
        His wife is unknown, but he had a son and a daughter:
 
        239.  Bleddyn ap Einion Fychan ap Einion
                Gwenllian ferch Einion Fychan ap Einion, born c. 1375.  She married Dafydd (c. 1365) ap Madog Lloyd (c. 1330) a half-brother of Dafydd ap Madog Lloyd who married Angharad ferch Ieuan ap Madog. (See #196 above)
 
Pen. 128, 617b cites "Einion Fychan ap Einion ap Cadwgan Ddu" as the father of Bleddyn
 
Pen. 127, 194/195 cites "Gwenllian ferch Bleddyn ap Einion Fychan" married "Dafydd ap Madog Lloyd ap Gruffudd ap Iorwerth Foel"; that Dafydd was born c. 1360 and his wife must have been a sister of Bleddyn, not a daughter.
 
198.  Dafydd ap Dafydd Goch ap Cadwgan Ddu, born c. 1345
        His wife is unknown, but he had 2 sons:
 
        240.  Cadwgan ap Dafydd ap Dafydd Goch
                Iolyn Goch ap Dafydd ap Dafydd Goch, born c. 1380.  His wife is unknown, but he had a son:
                       Hywel ap Iolyn Goch ap Dafydd, born c. 1410
 
Carrdiff 3.8, 149 cites "Dafydd ap Dafydd Goch" as the father of Cadwgan, while PF ii, 350 extends this to "Dafydd ap Dafydd Goch ap Cadwgan Ddu"
 
Pen. 287, 504 cites "Hywel ap Iolyn Goch ap Dafydd ap Dafydd Goch"
 
199.  Cadwgan Decca ap Iorwerth ap Cadwgan Ddu, born c. 1345
        He married a daughter (c. 1355) ferch Iorwerth Fychan (c. 1320) ap Iorwerth (c. 1285) ap Dafydd Hen (c. 1250) ap Gronwy (c. 1215) ap Iorwerth (c. 1185) ap Hywel (c. 1155) ap Moreiddig (c. 1125) ap Sandde Hardd (c. 1095) of Mortyn.  They had 2 sons:
 
        241.  Gruffudd ap Cadwgan Decca ap Iorwerth
        242.  Belyn ap Cadwgan Decca ap Iorwerth
 
Pen. 129, 110/111 cites "Cadwgan Decca ap Iorwerth ap Cadwgan Ddu" married "a daughter of Iorwerth Fychan ap Iorwerth ap Dafydd, while Pen 131, 125/126 extends her ancestry to "Iorwerth ap Dafydd ap Gronwy ap Iorwerth" and Pen. 131, 131 extends that to "Gronwy ap Iorwerth ap Hywel ap Moreiddig ap Sandde Hardd"

        His wife is unknown, but he had a son:
 
                Ieuan ap Dafydd ap Einion, born c. 1385.  He had a son:
                        Gruffudd ap Ieuan ap Dafydd, born c. 1415

202.  Iolyn ap Cynwrig ap Llywarch, born c. 1340
        His wife is unknown, but he had 2 sons:
 
        244.  Ieuan ap Iolyn ap Cynwrig
                Dafydd ap Iolyn ap Cynwrig, born c. 1375.  He married Angharad (c. 1385) ferch Gronwy ap Maredudd, whose ancestry is unknown.
 
Dwnn ii, 278 cites "Iolyn ap Cynwrig ap Llywarch" as the father of Ieuan
 
Pen. 136, 77 cites "Dafydd ap Iolyn ap Cynwrig ap Llywarch" married "Angharad ferch Gronwy ap Maredudd"
 
203.  Bleddyn ap Madog ap Madog Goch, born c. 1355
        His wife is unknown, but he had a son:
 
        245.  Cynwrig ap Bleddyn ap Madog
 
Dwnn ii, 300 cites "Bleddyn ap Madog ap Madog Goch" as the father of Cynwrig
 
204.  Gronwy Ddu ap Gronwy Gethyn ap Gronwy, born c. 1350
        His wife is unknown, but he had 2 sons and 2 daughters:
 
        246.  Edward ap Gronwy Ddu ap Gronwy Gethyn
                Ednyfed ap Gronwy Ddu ap Gronwy Gethyn, born c. 1385
                Mali ferch Gronwy Ddu ap Gronwy Gethyn, born c. 1380.  She married Gruffudd (c. 1365) ap Ieuaf Goch (c. 1330) ap Llewelyn (c. 1295) ap Ieuaf (c. 1265) ap Llewelyn (c. 1230) ap Ieuaf (c. 1195) ap Llewelyn (c. 1165) ap Cynwrig Efell (c. 1135), a base son of Madog ap Maredudd ap Bleddyn ap Cynfyn.
                Annes ferch Gronwy Ddu ap Gronwy Gethyn, born c. 1385.  She married Gruffudd (c. 1370) ap Iorwerth (c. 1340) ap Hywel (c. 1310) ap Iorwerth (c. 1275) ap Madog (c. 1245) ap Llewelyn (c. 1215) ap Madog Sutton (c. 1180) ap Elidyr (c. 1150) ap Rhys Sais II (c. 1115) descended from Tudor Trevor.
 
Pen. 128, 681a cites "Gronwy Ddu ap Gronwy Gethin" as the father of Ednyfed
 
Pen. 134, 177 & 195 cites "Mali ferch Gronwy Gethyn ap Gronwy" married "Gruffudd ap Ieuan Goch ap Llewelyn".  He was born c. 1365 and had a second wife born c. 1375, so Mali cannot be a daughter of Gronwy Gethyn and we make her a daughter of Gronwy Ddu ap Gronwy Gethyn.  The ancestry of Gruffudd is continued by Pen. 138, 153 as "Ieuan Goch ap Llewelyn ap Ieuaf" and by Pen. 131 54 as "Llewelyn ap Ieuaf ap Llewelyn ap Cynwrig Efell".  That construction is 2 generations deficient since a repeating pair of Ieuaf ap Llewelyn is omitted.
 
Pen. 128, 166a cites "Annes ferch Gronwy ap Cynwrig" married "Gruffudd ap Iorwerth ap Hywel ap Iorwerth ap Madog ap Llewelyn ap Madog Sutton ap Elidyr ap Rhys Sais".  This Gruffudd was born c. 1370, so Annes must be the daughter of Gronwy Ddu ap Gronwy Gethyn ap Gronwy ap Cynwrig.  See #164 above for another Annes ferch Gronwy who is misidentified in the source material.
 
 205.  Ieuaf ap Madog ap Gronwy, born c. 1345
        He married Mary, daughter of David Holland whose ancestry is unknown.  They had a son:
 
          247.  Iolyn ap Ieuaf ap Madog
 
Pen. 131, 52; Pen. 129, 84; Pen. 127, 136 cite "Ieuaf ap Madog ap Gronwy" as the father of Iolyn
 
PF v, 91 (citing BM Add 9864) says "Geoffrey ap Madog ap Gronwy" married "Mary, d. of David Holland".  This source alone calls Ieuaf "Geoffrey" and calls his son Iolyn "Oliver", probably the spelling used by the non-Welsh family of Ieuaf's wife
 
206.  Cynwrig ap Dafydd Ddu ap Hwfa, born c. 1345
        His wife is unknown, but he had a son:
 
             Llewelyn ap Cynwrig ap Dafydd Ddu, born c. 1375.  He married Efa (c. 1385) ferch Gwrgeneu (c. 1355) ap Gruffudd (c. 1320).  See #207 below.
 
Pen. 176, 344 cites "Llewelyn ap Cynwrig ap Dafydd Ddu ap Hwfa" married "Efa ferch Gwrgeneu ap Gruffudd Fychan ap Iolyn ap Ieuan".  Pen. 287, 506 drops the "Fychan" from Gruffudd ap Iolyn, a construction we prefer
 
207.  Gwrgeneu ap Gruffudd ap Iolyn, born c. 1355
        His wife is unknown, but he had 2 sons and a daughter:
 
              248.  Llewelyn ap Gwrgeneu ap Gruffudd
                      Maredudd ap Gwrgeneu ap Gruffudd, born c. 1390
                      Efa ferch Gwrgeneu ap Gruffudd, born c. 1385.  She married Llewelyn (c. 1375) ap Cynwrig (c. 1345) ap Dafydd Ddu (c. 1315).  See #206 above
 
Pen. 176, 334 cites "Efa ferch Gwrgeneu ap Gruffudd Fychan ap Iolyn" married "Llewelyn ap Cynwrig ap Dafydd Ddu.  We follow Pen. 287, 506 which deletes "Fychan" from Gruffudd ap Iolyn.
 
Pen. 287, 506 also cites "Gwrgeneu ap Gruffudd ap Iolyn" as the father of Llewelyn
 
Cardiff 3.8, 158 cites "Gwrgeneu ap Gruffudd Fychan ap Iolyn" as the father of Maredudd.  Again, we would delete "Fychan" from this Gruffudd
 
208.  Ednyfed ap Maredudd ap Iorwerth Fychan, born c. 1345
        His wife is unknown, but he had a son:
 
             249.  Dafydd ap Ednyfed ap Maredudd
 
Cardiff 3.8, 157 cites "Ednyfed ap Maredudd ap Iorwerth Fychan" as the father of Dafydd
 
209.  Gruffudd ap Gwilym ap Ithel, born c. 1345
        He married a daughter (c. 1355) ferch Ieuan (c. 1320) ap Dafydd (c. 1290) ap Gwrgeneu Fychan (c. 1260) ap Gwrgeneu (c. 1230) ap Iorwerth (c. 1195)  ap Lleision (c. 1165) ap Morgan (c. 1135) ap Caradog (c. 1105) ap Iestyn (c. 1075) ap Iestyn (c. 1040) ap Gwrgan (c. 1010), king of Glamorgan.  They had a son and a daughter:
 
            250.  Rhys ap Gruffudd ap Gwilym
                    Gwenhwyfar ferch Gruffudd ap Gwilym, born c. 1395.  She married Ednyfed (c. 1360) ap Gronwy (c. 1325) ap Adda (c. 1295) ap Ithel (c. 1265) ap Iarddur (c. 1235) ap Adda (c. 1205) ap Ithel (c. 1175) ap Iarddur (c. 1145) ap Diwrig (c. 1115) ap Bledrus (c. 1080) ap Merwydd Goch (c. 1040) ap Collwyn (c. 1010) ap Tangno.
 
Pen. 134, 147 cites "Gruffudd ap Gwilym ap Ithel" married "a daughter of Ieuan ap Dafydd ap Gwrgeneu Fychan ap Gwrgeneu ap Iorwerth ap Lleison ap Morgan", while Pen. 176, 307 extends her ancestry to "Lleison ap Morgan ap Caradog".  ABT 15 makes Morgan the son of Caradog ap Iestyn ap Gwrgan, but Caradog clearly was born c. 1100/05 while Iestyn ap Gwrgan was born 2 generations earlier near 1040. The 1175 Brut entry mentions this Morgan's mother as a sister of Lord Rhys, so Morgan was born no eaelier than 1135.  Our construction of the Glamorgan pedigrees requires both an Iestyn ap Gwrgan and an Iestyn ap Iestyn ap Gwrgan to achieve a stable timeline for the family. 
 
Pen. 134, 215 cites "Gruffudd ap Gwilym" as father of Rhys
 
Pen 134, 147 cites "Gwenhwyfar ferch Gruffudd ap Gwilym ap Ithel" married "Ednyfed ap Gronwy ap Adda ap Ithel ap Iarddur ap Diwrig ap Bledrus ap Merwydd Goch".  That construction is deficient by 3 generations, and we suggest that between Gronwy ap Diwrig there were two consecutive strings of men called Adda ap Ithel ap Iarddur. HLG 9f extends his pedigree to "Iarddur ap Diwrig ap Bledrus ap Merwydd ap Collwyn ap Tangno"
 
210.  Gronwy Fychan ap Gronwy Goch ap Dafydd Fychan, born c. 1345.
        His wife is unknown, but he had a son:
 
              Dafydd ap Gronwy Fychan ap Gronwy Goch, born c. 1375.  He had a daughter:
                     Erddylad ferch Dafydd ap Gronwy Fychan, born c. 1410.  She married Ieuan (c. 1395) ap Tudor (c. 1365) ap Llewelyn (c. 1330) descended from Yswatan Wyddel.  See #190 above for the rest of his pedigree. 
 
Pen. 134, 116 cites "Erddylad ferch Dafydd ap Gronwy Fychan ap Gronwy Goch ap Dafydd Fychan" married "Ieuan ap Tudor ap Llewelyn ap Philip ap Rhiryd ap Ieuan".
 
211.  Dafydd ap Cynddelw ap Ieuan, born 1345
        His wife is unknown, but he had a son:
 
             251.  Gruffudd ap Dafydd ap Cynddelw
 
Dwnn ii, 302 cites "Dafydd ap Cynddelw ap Ieuan" as the father of Gruffudd
 
212.  Dafydd ap Einion ap Cadwgan, born c. 1355
        His wife is unknown, but he had a son:
             252.  Ieuan ap Dafydd ap Einion
 
Harl. 2299 cites "Dafydd ap Einion ap Cadwgan" as the father of Ieuan
 
Pen. 176, 48 cites "Dafydd ap Einion ap Cadwgan ap Gwilym ap Ithel ap Y Gwion Gam"
 
213.  Madog Heddwch ap Hywel Goch ap Rhiwallon, born c. 1360
        He married a daughter (c. 1370) ferch Maredudd (c. 1340) ap Dafydd Llwch (c. 1305) ap Llewelyn (c. 1275) ap Gruffudd Fychan (c. 1245) ap Gruffudd (c. 1211) ap Gwenwynwyn (c. 1183) ap Gwenwynwyn (c. 1155) ap Owain Cyfeiliog (c. 1130) ap Gruffudd (c. 1095) ap Maredudd (c. 1065) ap Bleddyn (c. 1025) ap Cynfyn.  They had 2 sons:
            253.  Maredudd ap Madog Heddwch ap Hywel Goch
            254.  Einion ap Madog Heddwch ap Hywel Goch
 
Harl. 1982, 113v cites "Madog Heddwch ap Hywel Goch ap Rhiwallon" married "a daughter of Maredudd ap Dafydd Llwch", while Pen. 175, 147 extends her ancestry to "Dafydd Llwch ap Llewelyn ap Gruffudd Fychan ap Gruffudd ap Gwenwynwyn". ABT 8g extends that to "Gwenwynwyn ap Owain Cyfeiliog ap Gruffudd ap Maredudd ap Bleddyn ap Cynfyn"
 
Harl. 1977, 123v and Harl. 1982, 113v cite "Madog Heddwch ap Hywel Goch ap Rhiwallon" as the father of Maredudd
 
Pen. 135, 293 cites "Madog Heddwch" as the father of Einion, but carries his ancestry back no further
 
214.  Madog Lloyd ap Dafydd Fain ap Dafydd Wele, born c. 1365
        He married Tanw (c. 1380) ferch Dai (c. 1350) descended from Ednowain ap Bradwen.  They had a son:
 
            255.  Y Dai ap Madog Lloyd ap Dafydd Fain
 
Harl. 1973, 38 cites "Madog Lloyd ap Dafydd Fain ap Dafydd Wele" married "Tanw ferch y Dai ap Ieuan ap Dafydd Goch", while Pen. 128,, 731b extends her ancestry as "Ieuan ap Dafydd Goch ap Gruffudd ap Ednowain ap Bradwen".  This construction is 2 generations deficient, but our work on the line is not sufficient to suggest a solution
 
Dwnn i, 286 cites "Madog Lloyd ap Dafydd Fain" as the father of Dai
 
215.  Ednyfed ap Maredudd ap Einion, born c. 1365
        His wife is unknown, but he had a son:
 
              Llewelyn ap Ednyfed ap Maredudd, born c. 1400.  He had a daughter:
                    Gwenhwyfar ferch Llewelyn ap Ednyfed, born c. 1435.  She married Tudor (c. 1400) ap Ithel (c. 1400) ap Cynwrig (c. 1370) ap Iorwerth (c. 1340) ap Madog (c. 1310) ap Meilyr (c. 1280) ap Thomas (c. 1245) ap Owain (c. 1205) ap Bleddyn (c. 1175) ap Tudor (c. 1145) ap Rhys Sais II (c. 1115) descended from Tudor Trevor.
 
Pen. 127, 129 cites "Gwenhwyfar ferch Llewelyn ap Ednyfed ap Maredudd ap Einion" married "Tudor ap Ithel ap Cynwrig" while Pen. 134, 330 extends his ancestry as "Ithel ap Cynwrig ap Iorwerth ap Madog ap Meilyr ap Thomas ap Owain" and Pen 131, 126 continues "Meilyr ap Thomas ap Owain ap Bleddyn ap Tudor ap Rhys Sais"
 
216.  Ieuan ap Dafydd ap Rhiryd Ddu, born c. 1350
        He married Gwladys ferch Cynwrig Goch ap Bleddyn ap Dafydd of Fach-lwyd in Cyfeiliog, whose ancestry is unknown.  They had a son:
 
              Gruffudd ap Ieuan ap Dafydd, born c. 1380.  He married Marged (c. 1385) ferch Deio (c. 1350) ap Madog (c. 1320) ap Llewelyn Foel (c. 1290) ap Llewelyn (c. 1260) ap Madog (c. 1230) ap Llewelyn (c. 1195) ap Ithel (c. 1165) ap Heilyn (c. 1135) ap Eunydd (c. 1105) ap Heilyn (c. 1075) ap Eunydd (c. 1045) ap Morien (c. 1015) ap Morgeneu (c. 985) ap Gwerystan (c. 950).  Morgeneu ap Gwerystan was a brother of Cynfyn ap Gwerystan, the father of Bleddyn.
 
Pen. 287, 510 cites "Ieuan ap Dafydd ap Rhiryd Ddu" married "Gwladys ferch Cynwrig Goch ap Bleddyn ap Dafydd".
 
Harl. 1969, 448 and B.M. Add 28033, 331 cite "Gruffudd ap Ieuan ap Dafydd" married "Marged ferch Deio ap Madog". See the notes to #144 above for the remainder of her ancestry; she was a niece of Belyn ap Madog who married Alison ferch Llewelyn, a first-cousin of Ieuan ap Dafydd.
 
217.  Hywel ap Madog ap Rhiryd Ddu. born c. 1355
        His wife is unknown, but he had a son:

        His wife is unknown, but he had a son:
 
             256.  Ieuan ap Gado ap Maredudd
 
Harl. 1973, 26 cites "Gado ap Maredudd ap Meilyr" as the father of Ieuan
 
219.  Madog y Twpa ap Iorwerth Fychan ap Iorwerth, born c. 1355
        He resided at Plas y Twpa in Betws, Ceri; his wife is unknown but he had a son:
 
         257.  Ieuan ap Madog y Twpa ap Iorwerth Fychan
 
Dwnn i, 308/309 cites "Madog y Twpa ap Iorwerth Fychan ap Iorwerth" as the father of Ieuan.  But it wrongly cites as his wife a lady who was the second wife of his son.
                 
220.  Llewelyn ap Iorwerth Fychan ap Iorwerth, born c. 1355
        His wife is unknown, but he had a son:
 
        258.  Huw ap Llewelyn ap Iorwerth Fychan
 
PF ii, 347, note 2 cites "Llewelyn ap Iorwerth Fychan ap Iorwerth" as the father of Huw
 
221.  Ieuan ap Iorwerth Fychan ap Iorwerth, born c. 1355
        His wife is unknown, but he had a son:
 
        259.  Deio ap Ieuan ap Iorwerth Fychan
 
Harl. 1973, 26 cites "Ieuan ap Iorwerth Fychan ap Iorwerth" as the father of Deio
 
222.  Jonas Fychan ap Jonas ap Iorwerth, born c. 1355
        His wife is unknown, but he had a son :
 
        260.  Gruffudd ap Jonas Fychan ap Jonas
 
PF ii, 347 cites "Jonas Fychan ap Jonas ap Iorwerth" as the father of Gruffudd
 
223.  Iorwerth ap Trahaearn ap Iorwerth, born c. 1360
        His wife is unknown, but he had a son:
 
        261.  Trahaearn ap Iorwerth ap Trahaearn
 
Harl. 1973, 28 cites "Maredudd ap Trahaearn ap Iorwerth" and "Rhys Fychan ap Trahaearn ap Iorwerth", both of whom were born c. 1425.  Their father must have been born c. 1390, and we suggest he was the son of this Iorwerth ap Trahaearn"
 
224.  Einion ap Trahaearn ap Iorwerth, born c. 1365
        His wife is unknown, but he had a son:
 
        262.  Maredudd ap Einion ap Trahaearn
 
Harl. 1973, 21 cites "Hywel ap Maredudd ap Einion ap Trahaearn". He was born c. 1430 and requires a father born c. 1400 and a grandfather born c. 1365.   
 
225.  Maredudd ap Ieuan ap Madog Lloyd, born c. 1360
        His wife is unknown, but he had a son and 3 daughters:
 
        263.  Dafydd Goch ap Maredudd ap Ieuan
                Arddun ferch Maredudd ap Ieuan, born c. 1390.  She married Maredudd ap John Goch, whose ancestry is unknown.
                Sioned ferch Maredudd ap Ieuan, born c. 1395.  She married Ieuan (c. 1385) ap Madog y Twpa (c. 1355).  See #257
 
Dwnn i, 309 cites "Dafydd Goch ap Maredudd ap Ieuan, etc" intimating it was the same Maredudd ap Ieuan mentioned elsewhere in this same pedigree, i.e. ap Madog.
 
Pen. 287, 414 cites "Arddun ferch Maredudd ap Ieuan" married "Maredudd ap John Goch".  Dwnn i, 308/309 cites this Arddun as the mother of Gwenllian who was the mother of Dafydd who was the father of Cathryn; that Cathryn married Owain ap Hywel Goch, a son of Sioned the sister of Arddun. 
 
Dwnn i, 308/309 cites "Sioned ferch Maredudd ap Ieuan ap Madog" married "Ieuan ap Madog y Twpa"  See #257 below
 
226.  Ieuan ap Ieuan ap Madog Lloyd. born c. 1365.
        He married Gwenllian (c. 1375) ferch Gruffudd (c. 1340) ap Madog Fychan (c. 1310) ap Ieuan Foelfrych (c. 1280) ap Iorwerth Foel (c. 1240) ap Eginyr (c. 1210) ap Einion (c. 1180) ap Madog (c. 1150) ap Gwylog (c. 1120) ap Eginyr (c. 1085) ap Urien (c. 1055) ap Eginyr (c. 1025) ap Lles (c. 995) ap Idnerth Benfras of Maesbrook (c. 960).  They had a son:
 
              Gruffudd ap Ieuan ap Ieuan, born c. 1395.  He married Ales ferch Hywel Goch ap Hywel Fychan, whose ancestry is unknown. They had a son:
      
                   Thomas ap Gruffudd ap Ieuan, born c. 1425.  His son, Ieuan, born c. 1455, had a daughter:
 
                            Cathryn ferch Ieuan ap Thomas, born c. 1490.  She married Dafydd (c. 1480) ap Owain (c. 1450) ap Hywel Goch (c. 1420).  See #257
 
Dwnn i, 308/309 cites "Ieuan ap Ieuan ap Madog Lloyd" married "Gwenllian ferch Gruffudd ap Madog Fychan", while Pen. 176, 216 continues "Madog Fychan ap Ieuan Foelfrych"  The remainder of her pedigree is our construction since the sources are hopelessly anachronistic.
 
Dwnn i, 308/309 cites "Gruffudd ap Ieuan ap Ieuan" married "Ales ferch Hywel Goch ap Hywel Fychan", and further cites "Cathryn ferch Ieuan ap Thomas ap Gruffudd ap Ieuan ap Ieuan ap Madog Lloyd" married "Dafydd ap Owain ap Hywel Goch"
 
227.  Dafydd ap Ieuan Fychan ap Ieuan Dwy, born c. 1350
        His wife is unknown, but he had a son:
 
        264.  Deicws Lloyd ap Dafydd ap Ieuan Fychan
 
Dwnn i, 21 cites "Dafydd ap Ieuan Fychan ap Ieuan Dwy" as the father of Deicws Lloyd
 
228.  Roger Walcot ap Evan ap Dafydd, born c. 1360
        He married Edith Downes, daughter of Sir William Downes of Chester.  They had a son:
 
        265.  Sir Philip Walcot, son of Roger Walcot
 
Dwnn i, 111 and Vis. Shropshire, 476 cites "Roger Walcot son of Evan son of David" married "Edith, dau of Sir William Downes" and says Sir Philip was their son.
 
East Cheshire Past & Present (by J P Earwaker), pp 321 cites the pedigree of Sir Wiliam Downes as "son of William, son of William, son of Robert of Taxhall.
 
229.  Ieuan ap Maredudd ap Madog, born c. 1365
        He married Cathryn (c. 1375) ferch Ieuan (c. 1340) ap Madog (c. 1310) ap Einion (c. 1280) ap Gruffudd Fychan (c. 1245) ap Gruffudd (c. 1215) ap Rhys (c. 1185) ap Elidyr (c. 1150) ap Rhys Sais II (c. 1115) descended from Tudor Trevor.  They had a son:
 
        266.  Ieuan Bwl ap Ieuan ap Maredudd
 
Harl. 1973, 229 cites "Ieuan ap Maredudd ap Madog" married "Cathryn ferch Ieuan ap Madog ap Einion ap Gruffudd Fychan ap Gruffudd ap Rhys ap Elidyr".  We think this Elidyr is the man of that name known to be a son of Rhys Sais II.
 
230.  Owain ap Gronwy Sais ap Einion, born c. 1350
        His wife is unknown, but he had a son:

              Gruffudd ap Einion ap Gronwy Sais, born c. 1390.  He had a daughter:
                    Gwenllian ferch Gruffudd ap Einion, born c. 1425. She married Gruffudd (c. 1420) ap Jenkin Goch (c. 1390) ap Cynwrig (c. 1360) ap Madog (c. 1330) ap Gruffudd (c. 1300) ap Madog (c. 1270) ap Einion (c. 1240) ap Rhiryd (c. 1210) ap Iorwerth (c. 1180) ap Madog (c. 1145) ap Iorwerth (c. 1110) ap Madog (c. 1080) ap "Ednowain Bendew II" (c. 1050). 
 
Pen. 177, 150 cites "Gwenllian ferch Gruffudd ap Einion ap Gronwy Sais" married "Gruffudd ap Jenkin Goch ap Cynwrig ap Madog ap Gruffudd" while Pen. 134, 138 extends his ancestry as "Madog ap Gruffudd ap Madog ap Einion" and Pen. 127, 24 continues as "Madog ap Einion ap Rhiryd ap Iorwerth ap Madog".  All sources omit the second pair of "Iorwerth ap Madog" before continuing to Ednowain Bendew
 
233.  Madog Fychan ap Llewelyn Sais ap Einion, born c. 1355
        His wife is unknown, but he had a son:
 
              Gronwy Goch ap Madog Fychan ap Llewelyn Sais, born c. 1385.  He had a daughter:
 
                    Gwenllian ferch Gronwy Goch ap Madog Fychan, born c. 1420.  She married Ithel (c. 1410) ap Dafydd (c. 1380) ap Ithel Foel (c. 1350) ap Dafydd (c. 1320) ap Ithel Parson (c. 1290) ap Ithel Fychan (c. 1260) ap Ithel Gam (c. 1220) ap Ithel Lloyd (c. 1190) ap Ithel Gam Hen (c. 1155) ap Maredudd (c. 1120) ap Uchdryd (c. 1085) ap Uchdryd (c. 1055) ap Edwin of Tegeingl (c. 1020).
 
Pen. 135, 346/347 cites "Gwenllian ferch Gronwy Goch ap Madog Fychan ap Llewelyn Sais" married "Ithel ap Dafydd ap Ithel Foel ap Dafydd ap Ithel Person ap Ithel Fychan ap Ithel Lloyd"; but Ithel Parson's father Ithel Fychan was actually the son of Ithel Gam ap Ithel Lloyd (a brother of a different Ithel Fychan ap Ithel Lloyd), the only construction which follows a stable timeline.  The abundance of men named Ithel in this family caused many medieval genealogists to confuse one with another by disregarding chronology.
 
234.  Gwyn ap Llewelyn Sais ap Einion, born c. 1350.
        His wife is unknown, but he had a son:
 
               Hywel ap Gwyn ap Llewelyn Sais, born c. 1380.  He had a son:
                      Gwyn ap Hywel ap Gwyn, born c. 1410.  He married a daughter (c. 1415) ferch Sir Dafydd Chwitmor (c. 1380) ap Dafydd Chwitmor (c. 1350) ap Dafydd (c. 1320) ap Ithel Fychan (c. 1285) ap Ithel Lloyd (c. 1250) Ithel Gam (c. 1220) ap Ithel Lloyd (c. 1190) ap Ithel Gam Hen (c. 1155) ap Maredudd (c. 1120) ap Uchdryd (c. 1085) ap Uchdryd (c. 1055) ap Edwin of Tegeingl (c. 1020).
 
Pen. 135, 345 cites "Gwyn ap Hywel ap Gwyn ap Llewelyn Sais ap Einion" married "a daughter of Dafydd Chwitmor ap Dafydd ap Ithel Fychan ap Ithel Lloyd ap Ithel Gam".  With that construction, Bartrum's chart shows a missing generation.  2 wives are cited for a Dafydd Chwitmor and our work suggests there was a Sir Dafydd Chwitmor, son of Dafydd Chwitmor ap Dafydd.  The Ithel Fychan ap Ithel Lloyd ap Ithel Gam in his ancestry was a first-cousin of Ithel Person ap Ithel Fychan ap Ithel Gam cited in #233 above
 
235.  Jenkin ap Deicws ap Gronwy Sais, born c. 1360
        He married Mali Llwyd(c. 1375) ferch Dafydd (c. 1345) ap Ithel (c. 1310) ap Llewelyn (c. 1280) ap Cynwrig Sais (c. 1250) ap Ithel Fychan (c. 1220) ap Ithel Lloyd (c. 1190) ap Ithel Gam Hen (c. 1155) ap Maredudd (c. 1120) ap Uchdryd (c. 1085) ap Uchdryd (c. 1055) ap Edwin of Tegeingl (c. 1020).  They had a son:
 
             Gronwy ap Jenkin ap Deicws, born c. 1395
 
Pen. 134, 116 cites "Jenkin ap Deicws ap Gronwy Sais" married "Mali Llwyd ferch Dafydd ap Ithel ap Llewelyn ap Cynwrig of Northop".  We suspect this was the Cynwrig Sais of Northop found in Pen. 131, 186 as "Cynwrig Sais ap Ithel Fychan ap Ithel Lloyd ap Ithel Gam Hen".
 
Harl. 1969, 214 cites "Jenkin ap Deicws ap Gronwy Sais ap Einion" as the father of Gronwy.
    
236.  Ieuan ap Gronwy Ddu ap Rhys, born c. 1355
        He married Tangwystl (c. 1360) ferch Cynwrig (c. 1320) ap Bleddyn (c. 1290) ap Ithel Anwyl (c. 1260) ap Bleddyn (c. 1225) ap Ithel Lloyd (c. 1190) ap Ithel Gam Hen (c. 1155) ap Maredudd (c. 1120) descended from Edwin of Tegeingl.   They had a son:
             
            269.  Madog ap Ieuan ap Gronwy Ddu
 
Pen. 177, 45 cites "Ieuan ap Gronwy Ddu ap Rhys" married "Tangwystl ferch Cynwrig ap Bleddyn" while Pen. 129, 112 extends her ancestry as "Cynwrig ap Bleddyn ap Ithel Anwyl ap Bleddyn ap Ithel Lloyd ap Ithel Gam ap Maredudd"
 
Dwnn ii, 300 cites "Ieuan ap Gronwy Ddu" as the father of Madog
 
237.  Iolyn ap Tudor ap Rhys, born c. 1360
        His wife is unknown, but he had a son:
 
                Tudor ap Iolyn ap Tudor, born c. 1395.  He had a son:
                         Maredudd ap Tudor ap Iolyn, born c. 1430.  He married Angharad (c. 1445) ferch Rhys (c. 1415) ap Gruffudd Lloyd (c. 1385) ap Robin (c. 1355) ap Rhys (c. 1320) ap Robert (c. 1290) ap Gruffudd (c. 1260) ap Hywel (c. 1225) ap Gruffudd (c. 1195) ap Ednyfed Fychan (c. 1165).
 
Pen. 131, 67 cites "Maredudd ap Tudor ap Iolyn" married "Angharad ferch Rhys ap Gruffudd Lloyd ap Robin ap Rhys ap Robert ap Gruffudd ap Hywel ap Gruffudd ap Ednyfed Fychan.
 
Pen. 139(1), 82 cites "Maredudd ap Tudor ap Iolyn ap Tudor ap Rhys"
 
GENERATION 17:
 
238.  Madog ap Ieuan ap Madog, born c. 1370.
        His wife is unknown, but he had a son:
 
            270.  Ieuan ap Madog ap Ieuan
 
Pen. 128, 157a cites "Madog ap Ieuan ap Madog" as the father of Ieuan
 
239.  Bleddyn ap Einion Fychan ap Einion, born c. 1370
        He married Angharad (c. 1375) ferch Dafydd (c. 1345) ap Dafydd (c. 1310) ap Ieuan (c. 1280) ap Iorwerth (c. 1245) ap Dafydd (c. 1215) ap Iorwerth (c. 1185) ap Hywel (c. 1155) ap Moreiddig (c. 1125) ap Sandde Hardd (c. 1095).  They had 2 sons and a daughter:
 
          271.  Madog ap Bleddyn ap Einion Fychan
          272.  Gruffudd ap Bleddyn ap Einion Fychan
                  Efa ferch Bleddyn ap Einion Fychan, born c. 1405.  She married Llewelyn (c. 1395) ap Dafydd (c. 1365) ap Madog Fychan (c. 1335) ap Madog Wyddel (c. 1305) ap Madog (c. 1270) ap Einion (c. 1240) ap Rhiryd (c. 1210) ap Iorwerth (c. 1180) ap Madog (c. 1145) ap Iorwerth (c. 1110).  See #234 above for the remainder of his pedigree.
 
Pen. 128, 589a cites "Bleddyn ap Einion Fychan ap Einion" married "Angharad ferch Dafydd ap Dafydd ap Ieuan", while Pen. 128, 149a extends her ancestry to "Dafydd ap Dafydd ap Ieuan ap Iorwerth ap Dafydd".  It continues "Iorwerth ap Dafydd ap Gronwy ap Iorwerth" but her ancestor chronologically must have been "Iorwerth ap Dafydd ap Iorwerth" (omittiing Gronwy).  Both Dafydd ap Iorwerth and Gronwy ap Iorwerth were born c. 1215 and appear to be brothers.
 
Pen. 128, 589a also cites Bleddyn as the father of Madog and Gruffudd
 
Pen. 134, 257 cites "Efa ferch Bleddyn ap Einion Fychan" married "Llewelyn ap Dafydd ap Madog Fychan ap Madog Wyddel ap Madog ap Einion", while Pen. 131, 138 extends his ancestry as "Madog ap Einion ap Rhiryd ap Iorwerth ap Madog"
 
240.  Cadwgan ap Dafydd ap Dafydd Goch, born c. 1375.
        His wife is unknown, but he had a son:
 
             Dafydd ap Cadwgan ap Dafydd, born c. 1410.  He had a son:
                    Gruffudd ap Dafydd ap Cadwgan, born c. 1440.  He had a son:
                          Ieuan ap Gruffudd ap Dafydd, born c. 1470
 
PF ii, 350 (probably citing Cardiff 3.8, 149) cites "Ieuan ap Gruffudd ap Dafydd ap Cadwgan ap Dafydd ap Dafydd Goch ap Cadwgan Ddu"
 
241.  Gruffudd ap Cadwgan Decca ap Iorwerth, born c. 1375
        He married first, Mallt (c. 1385) ferch Ithel (c. 1350) ap Cynwrig (c. 1320) ap Bleddyn (c. 1290) ap Ithel Anwyl (c. 1260) ap Bleddyn (c. 1225) ap Ithel Lloyd (c. 1190) ap Ithel Gam Hen (c. 1155). See #233 above for the remainder of her pedigree.  By this wife, he had a son and a daughter:
 
          273.  Dafydd Lloyd ap Gruffudd ap Cadwgan Decca
                  Mallt ferch Gruffudd ap Cadwgan Decca, born c. 1410.  She married Gwyn (c. 1410) ap Madog (c. 1380) ap Dafydd Lloyd (c. 1345) ap Madog Goch (c. 1315) ap Heilyn Fychan (c. 1285) ap Heilyn (c. 1250) ap Ieuaf (c. 1215) ap Gruffudd (c. 1185) ap Llewelyn (c. 1150) ap Owain (c. 1115) ap Aldud (c. 1085) ap Owain (c. 1050) ap Edwin of Tegeingl (c. 1020).
 
       He married, secondly, Tangwystl (c. 1385) ferch Ieuan (c. 1355) ap Llewelyn (c. 1320) ap Gruffudd Lloyd (c. 1290) ap Maredudd (c. 1255) ap Llewelyn (c. 1225) ap Ynyr (c. 1190) descended from Sandde Hardd.  They had a son and a daughter:
 
           Gruffudd Goch ap Gruffudd ap Cadwgan Decca, born c. 1410
           Tangwystl ferch Gruffudd ap Cadwgan Decca, born c. 1415.  She married Ieuan ap Llewelyn ap Einion descended from Aleth of Dyfed.
 
Pen. 176, 60 cites "Gruffudd ap Cadwgan Decca" married "Mallt ferch Ithel ap Cynwrig ap Bleddyn ap Ithel Anwyl", while Pen. 129, 112 extends her ancestry as "Bleddyn ap Ithel Anwyl ap Bleddyn ap Ithel Lloyd ap Ithel Gam ap Maredudd ap Uchdryd".
 
Pen 176, 60 cites Gruffudd and Mallt as the parents of Dafydd Lloyd
 
Pen. 135, 353 cites "Mallt ferch Gruffudd ap Cadwgan Decca" married "Gwyn ap Madog ap Dafydd Lloyd ap Madog Goch ap Heilyn Fychan ap Heliyn ap Ieuaf ap Gruffudd ap Llewelyn ap Owain ap Aldud"
 
Pen. 129, 111 cites "Gruffudd ap Cadwgan Decca ap Iorwerth" married "Tangwystl ferch Ieuan ap Llewelyn" while Pen. 131, 134 extends her ancestry to "Ieuan ap Llewelyn ap Gruffudd Lloyd ap Maredudd ap Llewelyn ap Ynyr".  Many sources identify Llewelyn ap Ynyr as "ap Hywel ap Moreiddig ap Sandde Hardd". 
 
Pen. 129, 111 and 132 cite Gruffudd and Tagnwystl as the parents of Gruffudd Goch
 
Pen. 128, 822b cites "Tangwystl ferch Gruffudd ap Cadwgan Decca" married "Ieuan ap Llewelyn ap Einion".  The pedigree of his family contains a 2 generation gap, but we suspect he was "Ieuan ap Llewelyn ap Einion ap Celynin ap Einion ap Celynin ap Rhiryd ap Cynddelw ap Iorwerth ap Gwrgeneu ap Uchdryd ap Aleth"

 
242.  Belyn ap Cadwgan Decca ap Iorwerth, born c. 1380
        He married Gwen (c. 1395) ferch Dafydd (c. 1365) ap Madog Fychan (c. 1335) ap Madog Wyddel (c. 1305). See #239 above for the remainder of her pedigree. They had a son and a daughter:
 
          274.  Gruffudd ap Belyn ap Cadwgan Decca
                  Gwerfyl ferch Belyn ap Cadwgan Decca, born c. 1415.  She married Ieuan Wynn (c. 1405) ap Einion (c. 1375) ap Ieuan y Athro (c. 1340) ap Gruffudd (c. 1395) ap Dafydd Dinllais (c. 1270) ap Dafydd (c. 1235) ap Madog (c. 1205) ap Richard (c. 1175) ap Hywel (c. 1140) ap Llywarch (c. 1110) ap Rhiryd (c. 1080) ap Owain (c. 1050) ap Edwin of Tegeingl (c. 1020).
 
Dwnn ii, 321 cites "Heilyn ap Cadwgan Decca ap Iorwerth" married "Gwen ferch Dafydd ap Madog Fychan" while Pen. 129, 88b says "Belyn ap Cadwgan Decca ap Iorwerth" married "Gwen ferch Dafydd ap Madog Fychan ap Madog Wyddel". We think the spelling in Dwnn is corrupt, but it makes this couple the parents of Gruffudd.
 
PF iv, 181 (quoting Harl. 9865) cites "Gwerfyl ferch Belyn ap Cadwgan Decca ap Iorwerth" married "Ieuan Wynn ap Einion ap Ieuan y Athro ap Gruffudd ap Dafydd Dinllais ap Dafydd ap Madog ap Rhiryd ap Hywel ap Llywarch ap Rhiryd ap Owain ap Edwin".  However, earlier sources (Pen. 127, 136 and Pen. 128, 252b) say the father of the Madog in that list was Richard, not Rhiryd.
 
243.  Ieuan ap Hywel ap Cynwrig, born c. 1380
        His wife is unknown, but he had a son:
 
              Hywel ap Ieuan ap Hywel, born c. 1410.  He had a daughter:
                    Gwerfyl ferch Hywel ap Ieuan, born 1445.  She married Maredudd (c. 1435) ap Deicws (c. 1400) ap Madog (c. 1370) ap Adda Lloyd (c. 1340) ap Adda (c. 1310) ap Madog (c. 1280) ap Madog (c. 1245) ap Llewelyn (c. 1215) ap Madog Sutton (c. 1180) ap Elidyr (c. 1150) ap Rhys Sais II (c. 1115) descended from Tudor Trevor.
 
Pen. 135, 107 cites "Gwerfyl ferch Hywel ap Ieuan ap Hywel ap Cynwrig" married "Maredudd ap Deicws ap Madog ap Adda Lloyd ap Adda ap Madog", while Pen. 128, 906a extends his ancestry as "Adda Lloyd ap Adda ap Madog ap Madog ap Llewelyn ap Madog ap Elidyr ap Rhys Sais"
 
244.  Ieuan ap Iolyn ap Cynwrig, born c. 1370
        His wife is unknown, but he had a son:

245.  Cynwrig ap Bleddyn ap Madog, born c. 1385
        He married Angharad ferch Maredudd ap Rhys Fychan, whose ancestry is unknown.  They had a son:
 
              Ithel Fychan ap Cynwrig ap Bleddyn, born c. 1415.  He married Marged (c. 1425) ap Madog (c. 1395) ap Ieuan (c. 1355).  See #269 below.
 
Dwnn ii, 300 cites "Cynwrig ap Bleddyn ap Madog ap Madog Goch" married "Angharad ferch Maredudd ap Rhys Fychan of Cwm in Tegeingl". 
 
Harl. 1969, 110 cites the same marriage, but Bartrum's charts attach Cynwrig to "Bleddyn ap Madog ap Rhiryd ap Einion ap Cadwgan" descended from Gronwy ap Owain ap Edwin.  That construction fails chronologically; there is no evidence that Bleddyn ap Madog ap Rhiryd had a son named Cynwrig.
 
Pen. 135, 139 cites "Ithel Fychan ap Cynwrig ap Bleddyn ap Madog" married "Marged ferch Madog ap Ieuan ap Gronwy".  Dwnn ii, 300 cites the same marriage, but calls the lady "Annes"
 
246.  Edward ap Gronwy Ddu ap Gronwy Gethyn, born c. 1380.
        His wife is unknown, but he had a son:
 
         276.  Deio ap Edward ap Gronwy Ddu
 
PF v, 94 (citing the Cae Cyriog Ms) says "Edward ap Gronwy Ddu ap Gronwy Gethyn" was the father of Deio
 
247.  Iolyn ap Ieuaf ap Madog, born c. 1375
        He married Elen (c. 1375) ferch Iorwerth Sais (c. 1335) ap Iorwerth (c. 1305) ap Llewelyn (c. 1275) ap Iorwerth (c. 1240) ap Heilyn (c. 1210) ap Cowryd (c. 1175) ap Cadfan (c. 1140).  They had 2 sons:

                 Ithel Fychan ap Iolyn ap Ieuaf, born c. 1395
 
Pen. 129, 84; Pen. 127, 136; Pen. 128, 213b cite "Iolyn ap Ieuaf" married "Elen ferch Iorwerth Sais ap Iorwerth ap Llewelyn ap Iorwerth ap Heilyn ap Cowryd ap Cadfan"
 
PF v, 91 (citing B.M. Add. 9854) calls Iolyn "Oliver" but assigns him the same wife and makes them parents of Llewelyn Fychan
 
Pen. 287, 540; Pen. 134, 185; Pen. 135, 110 cite "Iolyn ap Ieuaf" as the father of "Llewelyn Fychan"
 
Cardiff Ms 3.8, 210 cite "Iolyn ap Ieuaf" as the father of Ithel Fychan
 
248.  Llewelyn ap Gwrgeneu ap Gruffudd, born c. 1390
        His wife is unknown, but he had a son:
 
               Rhys ap Llewelyn ap Gwrgeneu, born c. 1420.  He had a daughter: 
                     Ales ferch Rhys ap Llewelyn, born c. 1450.  She married Ithel (c. 1445) ap Jenkin (c. 1410) ap Dafydd (c. 1380) ap Hywel (c. 1350) ap Einion (c. 1315) ap Ieuan (c. 1285) ap Ithel (c. 1255) ap Gruffudd (c. 1220) ap Dafydd (c. 1185) ap Gronwy (c. 1150) ap Maredudd (c. 1120) ap Uchdryd (c. 1085) ap Uchdryd (c. 1055) ap Edwin of Tegeingl (c. 1020).
 
Pen. 287, 225/226 cites "Ales ferch Rhys ap Llewelyn" (extended to Llewelyn ap Gwrgeneu ap Gruffudd by Pen. 287, 506) married "Ithel ap Jenkin ap Dafydd ap Hywel ap Einion ap Ieuan ap Ithel ap Gruffudd ap Dafydd"; Pen. 287, 133 extends his ancestry as "Gruffudd ap Dafydd ap Gronwy" while Pen. 135, 257 continues as "Dafydd ap Gronwy ap Maredudd ap Uchdryd".
 
249.  Dafydd ap Ednyfed ap Maredudd, born c. 1375
        His wife is unknown, but he had a son:
 
              Gruffudd Lloyd ap Dafydd ap Ednyfed, born c. 1410.  He had a son:
                     John ap Gruffudd Lloyd ap Dafydd, born c. 1440.  He married Lleuci (c. 1450) ferch Ieuan (c. 1420) ap Gwyn (c. 1385) ap Gruffudd (c. 1355).  See #268 below.
 
Cardiff 3.8. 157 cites "John ap Gruffudd Lloyd ap Dafydd ap Ednyfed" married "Lleuci ferch Ieuan ap Gwyn", while Dwnn ii, 320 extends her ancestry to "Ieuan ap Gwyn ap Gruffudd" and Dwnn ii, 321/322 extends that to "Gwyn ap Gruffudd ap Gronwy Sais ap Einion ap Llywarch ap Llewelyn ap Ithel Talfrith".  Several other citations omit Llywarch from that list of ancestors, but fail chronologically.
 
250.  Rhys ap Gruffudd ap Gwilym, born c. 1375
        He married Gwerfyl ferch Rhys ap Bleddyn, whose ancestry is unknown.  The had a son:
 
               Dafydd ap Rhys ap Gruffudd, born c. 1410.  He married a daughter (c. 1420) ferch Tudor (c. 1385) ap Ieuan (c. 1355) ap Llewelyn (c. 1320) ap Gruffudd Lloyd (c. 1290) ap Maredudd (c. 1255) ap Llewelyn (c. 1225) ap Ynyr (c. 1190) descended from Sandde Hardd.

251.  Gruffudd ap Dafydd ap Cynddelw, born c. 1375.
        His wife is unknown, but he had a son:

PF ii, pp 340 (citing Harl. 2299) says "Morfydd ferch Dafydd ap Ieuan ap Dafydd ap Einion ap Cadwgan ap Gwilym ap Ithel ap Y Gwion Gam" married "Gruffudd ap Ithel ap Gruffudd ap Dafydd ap Madog Fychan ap Madog Wyddel"
 
253.  Maredudd ap Madog Heddwch ap Hywel Goch, born c. 1390
        He married Mali (c. 1400) ferch Ieuan Fychan (c. 1370) ap Ieuan Gethyn (c. 1335) ap Madog Cyffin (c. 1300) descended from Einion Efell, a base son of Madog ap Maredudd ap Bleddyn ap Cynfyn.  They had a son:

Harl. 1982, 113v cites "Maredudd ap Madog Heddwch ap Hywel Goch" married "Mali ferch Ieuan Fychan ap Ieuan Gethyn", while Pen. 129, 51 and Pen 127, 157 extend her ancestry to "Ieuan Fychan ap Ieuan Gethyn ap Madog Cyffyn" and Pen. 131, 103; Pen. 131, 138; Pen 131, 286; Pen 129, 49 and 92 continue as "Madog Cyffyn ap Madog Goch ap Ieuaf ap Cuhelyn ap Rhun ap Einion Efell".
 
The children and grandchildren of Maredudd all were born after 1400 when our source material ends.  The data shown for them was taken from Bartrum's charts in his Welsh Genealogies AD 300-1400, but those families connected by marriage were extended back to well-known ancestors by actual sources which may differ from Bartrum's charts
 
254.  Einion ap Madog Heddwch ap Hywel Goch, born c. 1395
        He married a daughter (c. 1405) ferch Morys Cyffin (c. 1375) ap Ieuan Gethyn (c. 1335) ap Madog Cyffin (c. 1300) descended from Einion Efell.  They had 2 sons:

Pen. 135, 293 cites "Einion ap Madog Heddwch" married "a daughter of Morys ap Ieuan Gethyn.  She was a first-cousin of Mali ferch Ieuan Fychan in #253 above. While John and Gruffudd ap Einion (and John's marriage) are shown on Bartrum's chart "Llywelyn Eurdorchog 12", he included no sources for persons born after 1400
 
255.  Y Dai ap Madog Lloyd ap Dafydd Fain, born c. 1400
        He married Mawd (c. 1415) ferch Hywel Gethyn (c. 1385) ap Gruffudd Gethyn (c. 1355) ap Rhiryd (c. 1325) ap Gruffudd Drwyndwn (c. 1295).  See #253 above for the remainder of her pedigree.  They had 5 sons and a daughter:

            Ieuan ap Y Dai ap Madog Lloyd, born c. 1435.  He married Gwerfyl (c. 1445) ferch Madog (c. 1415) ap Gruffudd Bach (c. 1385) ap Ieuan Fychan (c. 1355) ap Ieuan (c. 1325) ap Iorwerth (c. 1295) ap Ieuaf (c. 1265) ap Cyfnerth (c. 1235) ap Iddon (c. 1205).  See #255 above for the rest of her pedigree.
            Einion ap Y Dai ap Madog Lloyd, born c. 1435

             Elen ferch Y Dai ap Madog Lloyd, born c. 1430.  She married Maredudd (c. 1420) ap Ieuan Gethyn (c. 1390) ap Gruffudd Gethyn (c. 1355) ap Ieuan (c. 1325) ap Dafydd (c. 1290) ap Gwyn (c. 1260) ap Dafydd (c. 1230) ap Ieuan (c. 1195) ap Hywel Goch (c. 1165) ap Dafydd (c. 1130) ap Cadwgan (c. 1090) ap Rhiryd (c. 1055) ap Bleddyn (c. 1025) ap Cynfyn (c. 990). 
 
Harl. 1982, 16 cites "Dai ap Madog Lloyd" married "Mawd ferch Hywel Gethyn ap Gruffudd Gethyn.  Her ancestry is extended in the notes to #255 above
 
Bartrum's chart 'Llywelyn Eurdorchog 11' says "Hywel ap y Dai ap Madog Lloyd" married "Mali ferch Ieuan ap Tudor" while Pen. 127, 142 extends her ancestry to "Ieuan ap Tudor ap Gronwy ap Hywel y Gadair ap Gruffudd ap Madog" and Pen. 131, 281 continues "Gruffudd ap Madog ap Iorwerth ap Madog ap Rhiryd Flaidd"
 
Pen. 287, 1426 cites "Gruffudd ap Y Dai ap Madog Lloyd" married "Angharad ap Owain ap Ieuan Lloyd ap Einws"" while Pen. 287, 1411 extends her ancestry as "Ieuan Lloyd ap Einws ap Einion ap Heilyn of Caereinion".  We believe the father of Heilyn was one of the sons of Trahaearn ap Pasgen, either Rhiryd or Hywel.  This would be Pasgen III born c. 1180 of the First Powys Dynasty.  Alternatively, the name "Heilyn of Caereinion" may be an error; Rhiryd ap Hywel ap Trahaearn ap Pasgen had a son named Einion, also born c. 1310, who had a son called Einws.
 
B.M. Add 9866, 99 cites "Ieuan ap Dai ap Madog Lloyd" married "Gwerfyl ferch Madog ap Gruffudd Bach ap Ieuan Fychan ap Ieuan ap Iorwerth Foel", while Pen 131, 285 extends her ancestry to "Ieuan ap Iorwerth Foel ap Ieuaf Sais ap Cyfnerth".  See #253 above for the continuation of her ancestry.

Harl. 1973, 26 cites "Iorwerth ap Gwgan ap Ieuan ap Gado ap Maredudd" married "Nest ferch Maredudd ap Ieuan ap Madog", while Pen. 128, 712a extends her ancestry to "Ieuan ap Madog ap Maredudd ap Gruffudd ap Einion ap Llewelyn ap Meilyr Gryg".  Chronologically, this would be the c. 1190 Meilyr Gryg who occurs 5 generations after the earlier man of that name.
 
257.  Ieuan ap Madog y Twpa ap Iorwerth Fychan, born c. 1385.
        He married first, Sioned (c. 1395) ferch Maredudd (c. 1360) ap Ieuan (c. 1330) ap Madog Lloyd (c. 1295).  See #225 above  He married secondly, Arddun (c. 1385) ferch Hywel (c. 1355) ap Maredudd (c. 1325) ap Hywel (c. 1290) ap Adda (c. 1255) ap Madog (c. 1225) ap Maredudd (c. 1200) ap Maelgwn II (c. 1172) ap Maelgwn (c. 1143) ap Cadwallon (c. 1114) ap Madog (c. 1085) ap Idnerth (c. 1050) ap Cadwgan (c. 1020) ap Elystan Glodrydd.  Ieuan had two sons by his first wife:

261.  Trahaearn ap Iorwerth ap Trahaearn, born c. 1395
        His wife is unknown, but he had 2 sons:
 
                 Maredudd ap Trahaearn ap Iorwerth, born c. 1425.  He married Myfanwy (c. 1435) ferch Ieuan Goch (c. 1400) ap Madog (c. 1365) ap Einion (c. 1330) ap Hywel (c. 1300) ap Tudor (c. 1270) ap Einion Fychan (c. 1235) ap Einion (c. 1205) ap Meurig (c. 1175) ap Ieuaf (c. 1145) ap Gronwy (c. 1115) ap Ifor (c. 1085) ap Idnerth (c. 1050) ap Cadwgan (c. 1020) ap Elystan Glodrydd (c. 990) of Fferlys.
                 Rhys Fychan ap Trahaearn ap Iorwerth, born c. 1425.  He married Alison (c. 1440) ferch Maredudd (c. 1410) ap Ieuan (c. 1380).  She was a sister of Nest in #256 above.
 
Harl. 1973, 28 cites "Maredudd ap Trahaearn ap Iorwerth" married "Myfanwy ferch Ieuan Goch ap Madog" while Pen. 128, 124a extends her ancestry to "Ieuan Goch ap Madog ap Einion ap Hywel ap Tudor ap Einion Fychan ap Einion" and Pen. 128, 723b continues that Einion to "ap Meurig ap Ieuaf ap Gronwy".  Pen. 127, 102 continues "Ieuaf ap Gronwy ap Ifor ap Idnerth ap Cadwgan ap Elystan".
 
Harl. 1973, 28 cites "Rhys Fychan ap Trahaearn ap Iorwerth" married "Alison ferch Maredudd ap Ieuan" and Pen. 128, 712a extends her ancestry back to Meilyr Gryg as shown under #256 above
 
262.  Maredudd ap Einion ap Trahaearn, born c. 1400
        His wife is unknown, but he had 2 sons:
 
                Hywel ap Maredudd ap Einion, born c. 1430.  He married Annes (c. 1440) ferch Maredudd (c. 1410) ap Ieuan (c. 1380).  She was a sister of Nest in #256 above.
                Gruffudd ap Maredudd ap Einion, born c. 1435.  He married Sioned (c. 1445) ferch Maredudd (c. 1410) ap Ieuan (c. 1380).  She was a sister of Annes, next above.
 
Harl, 1973, 21 cites "Hywel ap Maredudd ap Einion ap Trahaearn" married "Annes ferch Maredudd ap Ieuan"; her ancestry back to Meilyr Gryg is shown in #256 above
 
Harl 1973, 28 cites "Gruffudd ap Maredudd ap Trahaearn" married "Sioned ferch Maredudd ap Ieuan".  Since Sioned was a sister of Annes (who married the brother of Gruffudd), this citation should read "Gruffudd ap Maredudd ap Einion ap Trahaearn".  Another sister of Sioned and Annes was Alison who married Rhys Fychan (#261 above), a second cousin of Hywel and Gruffudd.
 
263.  Dafydd Goch ap Maredudd ap Ieuan, born c. 1390
        His wife is unknown, but he had a daughter:
 
                Efa ferch Dafydd Goch ap Maredudd, born c. 1420.  She married John (c. 1405) ap Dafydd (c. 1375) ap Tudor Fychan (c. 1345) ap Ednyfed Goch (c. 1315) ap Gruffudd (c. 1285) ap Einion (c. 1250) ap Llewelyn (c. 1220) ap Meilyr Gryg II (c. 1190)
 
Dwnn i, 308/309 cites "Efa ferch Dafydd Goch ap Maredudd ap Ieuan" married John ap Dafydd ap Tudor Fychan" while Dwnn i, 236 extends his ancestry to "Dafydd ap Tudor Fychan ap Ednyfed Goch ap Gruffudd".  Harl 1973, 48 continues "Gruffudd ap Einion ap Llewelyn ap Meilyr Gryg" although Bartrum's chart "Ednyfed Goch" fails to connect him to anyone.
 
264.  Deicws Lloyd ap Dafydd ap Ieuan Fychan, born c. 1380.
        He married Gwerfyl (c. 1390) ferch Dafydd (c. 1360) ap Llewelyn Fychan (c. 1325) ap Llewelyn (c. 1295) ap Adda (c. 1265) ap Gruffudd (c. 1230) ap Gronwy (c. 1195) ap Gwyn (c. 1165) ap Ieuan (c. 1130) ap Cadfan (c. 1100) ap Cadfael (c. 1070) ap Mathew Hen (c. 1040) ap Brochwel III (c. 1005) ap Aeddan III (c. 975) ap Selyf II (c. 945).  See #141 above for the rest of her pedigree.  They had a daughter:
 
               Angharad ferch Deicws Lloyd ap Dafydd, born c. 1410.  She married David Dwnn (c. 1395) ap Maredudd (c. 1365) ap Henry Dwnn (c. 1330) ap Gruffudd Gethyn (c. 1300) ap Cadwgan (c. 1270) ap Gruffudd (c. 1240) ap Cadwgan Fawr (c. 1210) ap Cadwgan (c. 1180) ap Gruffudd Fychan (c. 1150) ap Gruffudd (c. 1120) ap Llewelyn (c. 1090) ap Gwrgan (c. 1060).  This was a family of Cydweli whose early ancestry is usually traced to a Pliws Hen, king of Dyfed in the early 8th century.
 
Dwnn i, 21 cites "Deicws Lloyd ap Dafydd ap Ieuan Fychan" married "Gwerfyl ap Dafydd ap Llewelyn" but Pen. 128, 736a calls him "Dafydd ap Llewelyn Fychan ap Llewelyn ap Adda ap Gruffudd ap Gronwy" and Dwnn i, 302/303 extends that to "Gruffudd ap Gronwy ap ap Gwyn ap Cuan ap Cadfan ap Cadfael ap Maredudd Hen".
Some citations call the latter Bod Hen (Bod was a nickname for Matthew) and try to attach him to Brochwel Ysgithrog, but his father, Brochwel, would be born c. 1005
 
Dwnn i, 21 also cites "Angharad ferch Deicws Lloyd ap Dafydd ap Ieuan Fychan" married "Dafydd Dwnn ap Maredudd ap Henry Dwnn ap Gruffudd Gethyn ap Cadwgan ap Gruffudd ap Cadwgan Fawr ap Cadwgan ap Gruffudd Fychan ap Gruffudd ap Llewelyn ap Gwrgan". 
 
265.  Sir Philip Walcot, son of Roger Walcot, born c. 1390.
        He married Julia (c. 1400), daughter of John Harley (c. 1365) son of Robert Harley (c. 1335) son of Richard Harley (c. 1300) son of Robert Harley (c. 1270) of Brampton Bryan, Herefordshire.  They had a son:
                John Walcot, born c. 1425.  He married Ales (c. 1440), a base daughter of Dafydd Lloyd (c. 1415) ap Sir Gruffudd Fychan (c. 1385).  Sir Gruffudd was the representative of the senior line descended from the First Powys Dynasty, and was slain in 1447.  John and Ales had a son:
 
                       Roger Walcot, born c. 1455.  He married Marged (c. 1465) ap Dafydd Lloyd, the bard of Mathafern (c. 1430).  The latter entertained Henry Tudor as he traveled to Bosworth Field in 1485, and wrote a poem predicting his victory over King Richard III.  Dafydd Lloyd descended from Einion ap Seisyllt of Mathafern.
 
          We suspect Sir Philip had another son, William born c. 1430, who was murdered in 1462 for adultry and whose base son, Thomas, resided with his mother in Devonshire where the family name was spelled Wolcott.  This might be the unproven line from which the American Wolcott family descended.
 
Dwnn i, 111 and Vis. Shropshire, 476 cite "Sir Philip Walcot, son of Roger" married "Julia, dau of John Herle".  This was the Welsh spelling of "Harley"; his ancestry is cited in Vis. Shropshire, 304/305
 
The original two sources just mentioned also cite "John Walcot, son of Sir Philip Walcot" married "Alice ferch Dafydd Lloyd ap Sir Gruffudd Fychan".  Montgomeryshire Collections, viii, 399 gives his pedigree as "ap Gruffudd ap Ieuan ap Madog ap Gwynwys ap Gruffudd ap Beli ap Selyf ap Brochwel ap Aeddan." Chronologically, this must have been Brochwel IV ap Aeddan IV, "ap Selyf III ap Brochwel III"; that Selyf III was a brother of Matthew Hen discussed in #264 above.
 
The same sources say John Walcot ap Sir Philip had a son named Roger.  Dwnn i, 111 says that Roger married "Marged ferch Dafydd Lloyd of Mathafern".  Vis. Shropshire, 477 incorrectly assigns that marriage to another Roger Walcot, the son of a different John Walcot, which fails chronologically.
 
Early members of the Wolcott family which came to America in 1630 bore the arms of the Shropshire Walcot family.  Attempts by the American Wolcott family to link to a John Walcot living in 1415 have not resulted in a convincing pedigree.  We suspect the link is through an illegitimate son of a William ap Sir Philip Walcot whom we would identify with the William Walcot murdered in 1462, probably the same man called William Willascot in Vis. Shropshire, 448 as the first husband of Elisabeth Stury.

 
266.  Ieuan Bwl ap Ieuan ap Maredudd, born c. 1395
         He married Marged ferch Rhys ap Maredudd ap Dafydd Chwith, whose ancestry is unknown.  He had a son:
 
              Philip ap Ieuan Bwl ap Ieuan, born c. 1425.  He married Gwenhwyfar (c. 1435) ferch Dafydd Lloyd (c. 1400) ap Gruffudd (c. 1370) ap Einion (c. 1335) ap Iorwerth (c. 1305) ap Maredudd (c. 1270) ap Madog (c. 1240) ap Maredudd (c. 1205) ap Madog Danwr (c. 1175) descended from Tudor Trevor.  They had a son:
                      Ieuan ap Philip ap Ieuan Bwl, born c. 1460.  He married Angharad (c. 1470) ferch Morys (c. 1435) ap Dafydd (c. 1400) ap Llewelyn (c. 1365) ap Rhys (c. 1330) ap Llewelyn (c. 1300) ap Gruffudd (c. 1265) ap Rhys (c. 1235) ap Iorwerth (c. 1200) ap Hywel (c. 1170) ap Cadifor (c. 1135) ap Dyfnwal (c. 1100) descended from Tudwal Gloff ap Rhodri Mawr.  Their son:
                             Jenkin ap Ieuan ap Philip, born c. 1495, married Gwenhwyfar (c. 1510) ferch Mathew (c. 1480) ap Llewelyn (c. 1450) ap Ieuan (c. 1420) ap Maredudd (c. 1390) ap Madog Goch (c. 1360) ap Madog Fychan (c. 1330) ap Madog (c. 1300) ap Ieuan (c. 1270) ap Gruffudd Goch (c. 1240) ap Maredudd (c. 1205) ap Madog Danwr (c. 1175) descended from Tudor Trevor.  Their son:
                                     David Lloyd ap Jenkin, born c. 1525, was High Sheriff for Montgomeryshire in 1574.  He married Lowry (c. 1540) ferch Owain Gwyn (c. 1510) ap Llewelyn Lloyd (c. 1480) ap Ieuan (c. 1450) ap Rhys (c. 1420) ap Adda (c. 1390) ap Hywel (c. 1360) ap Adda Ddu (c. 1330) descended from Einion ap Cynfelyn of Maesmawr.
 
Dwnn i, 311 and Harl. 1973, 119 cite "Ieuan Bwl ap Ieuan ap Maredudd ap Madog" married Marged ferch Rhys ap Maredudd ap Dafydd Chwith".
 
Montgomeryshire Collections vii, 55 cites "Philip ap Ieuan Bwl ap Ieuan" married "Gwenhwyfar ap Dafydd Lloyd ap Gruffudd ap Einion ap Iorwerth ap Maredudd ap Madog" whom it mistakes for Madog Danwr.  Our work finds this was "Maredudd ap Madog ap Maredudd ap Madog Danwr".
 
Dwnn i, 311 cites "Ieuan ap Philip ap Ieuan Bwl" married "Angharad ferch Morys ap Dafydd ap Llewelyn ap Rhys", while Bodleian Add C 177, 26 extends that to "Llewelyn ap Rhys ap Llewelyn ap Gruffudd ap Rhys".  Pen. 128, 664b extends that as "Llewelyn ap Gruffudd ap Rhys ap Iorwerth" and Dwnn i, 26 completes it as "Rhys ap Iorwerth ap Hywel ap Cadifor ap Dyfnwal".  Several of the intervening sources became corrupt where we ceased to cite them, linking this family to Collwyn ap Tangno or Einion ap Collwyn, all which fail chronologically.
 
Dwnn i, 311 cites "Jenkin ap Ieuan ap Philip" married "Gwenhwyfar ferch Mathew ap Llewelyn ap Ieuan ap Maredudd" and PF ii, 272 extends that as "Mathew ap Llewelyn ap Ieuan ap Maredudd ap Madog Goch ap Madog Fychan ap Madog ap Ieuan ap Maredudd ap Madog Danwr", a construction which is 1 generation short of satisfactory.  Pen. 138, 358 cites a "Ieuan ap Gruffudd Goch ap Maredudd ap Madog Danwr" and we would insert Gruffudd Goch into the pedigree of Gwenhwyfar.
 
Dwnn i, 311 cites "Dafydd Lloyd ap Jenkin ap Ieuan" married "Lowry Gwyn ferch Owain Gwyn ap Llewelyn" while Dwnn i, 310 extends that as "Owain Gwyn ap Llewelyn Lloyd ap Ieuan ap Rhys ap Adda ap Hywel ap Adda Ddu"
 
267.  Madog ap Owain ap Gronwy Sais, born c. 1380
        His wife is unknown, but he had a daughter:
 
               Gwenllian ferch Madog ap Owain, born c. 1415.  She married Madog (c. 1400) ap Bleddyn (c. 1370) ap Einion Fychan (c. 1340).  See #271 below.
 
See #271 for sources citing the parents and spouse of Gwenllian
 
268.  Gwyn ap Gruffudd ap Gronwy Sais, born c. 1385.
        His wife is unknown, but he had 2 sons and 2 daughters:
 
              Nicholas ap Gwyn ap Gruffudd, born c. 1415.  He married Marged (c. 1425) ferch Ieuan (c. 1390) ap Rhys Gethyn (c. 1355) ap Gruffudd Fychan (c. 1320) ap Gruffudd (c. 1290) ap Dafydd Goch (c. 1260) ap Dafydd (c. 1230) ap Gruffudd (c. 1200) ap Llewelyn (c. 1170) ap Iorwerth (c. 1135) ap Nefydd Hardd (c. 1105)
              Ieuan ap Gwyn ap Gruffudd, born c. 1420. He had a daughter:
                   Llueci ferch Ieuan ap Gwyn, born c. 1450.  She married John (c. 1440) ap Gruffudd Lloyd (c. 1410) ap Dafydd (c. 1375).  See #249 above.  Ieuan ap Gwyn ap Gruffudd also had a son, Rhys, and another unnamed daughter.
              Cristyn ferch Gwyn ap Gruffudd, born c. 1415. She married Gronwy (c. 1400) ap Gwilym (c. 1360) ap Maredudd (c. 1325) ap Gruffudd Lloyd (c. 1290) ap Maredudd (c. 1255) ap Llewelyn (c. 1225) ap Ynyr (c. 1190) ap Hywel (c. 1155) ap Moreiddig (c. 1125) ap Sandde Hardd of Mortyn (c. 1095)
              Angharad ferch Gwyn ap Gruffudd, born c. 1415.  She married Llewelyn (c. 1400) ap Dafydd (c. 1365) ap Ednyfed (c. 1335) ap Gruffudd (c. 1300) ap Jenkin (c. 1270) ap Llewelyn (c. 1240) ap Einion (c. 1205) ap Rhiryd (c. 1170) ap Einion (c. 1140) ap Cadwgan (c. 1110) ap Gronwy (c. 1080) ap Owain (c. 1050) ap Edwin of Tegeingl (c. 1020)
 
Dwnn ii, 321 cites "Nicholas ap Gwyn ap Gruffudd ap Gronwy Sais" married "Marged ferch Ieuan ap Rhys Gethyn", while Pen. 127, 57 extends her ancestry as "Ieuan ap Rhys Gethyn ap Gruffudd Fychan" and Pen. 131, 59 continues as "Rhys Gethyn ap Gruffudd Fychan ap Gruffudd ap Dafydd Goch of Penmachno ap Dafydd ap Gruffudd ap Llewelyn ap Iorwerth".  Pen. 287, 677 cites "Iorwerth of Penmachno ap Nefydd Hardd"
 
Dwnn ii, 322 cites "Gwyn ap Gruffudd ap Gronwy Sais" as the father of Ieuan
 
Cardiff 3.8, 157 cites "Lleuci ferch Ieuan ap Gwyn ap Gruffudd" married "John ap Gruffudd Lloyd ap Dafydd"; see #249 above
 
Pen. 131, 144 cites "Cristyn ferch Gwyn ap Gruffudd ap Gronwy Sais" married "Gronwy ap Gwilym ap Maredudd ap Gruffudd Lloyd", while Dwnn ii, 89 extends his ancestry as "Gruffudd Lloyd ap Maredudd ap Llewelyn ap Ynyr ap Hywel ap Moreiddig"
 
Dwnn ii, 322 cites "Angharad ferch Gwyn ap Gruffudd ap Gronwy Sais" married "Llewelyn ap Dafydd ap Ednyfed ap Gruffudd ap Jenkin ap Llewelyn ap Einion ap Cadwgan ap Gronwy ap Owain ap Edwin"; that construction lacks two generations to reach back to Edwin.  We believe the Einion in this list was the son of the "Rhiryd ap Einion ap Cadwgan ap Gronwy ap Owain ap Edwin" cited in Pen. 129, 109/110 and that the Dwnn citation skipped from Einion ap Rhiryd to Einion ap Cadwgan.
 
269.  Madog ap Ieuan ap Gronwy Ddu. born c. 1395
        He married a daughter (c. 1410) ferch Dafydd (c. 1375) ap Gruffudd Benfras (c. 1345) ap Gruffudd Fychan (c. 1315) ap Gruffudd (c. 1280) ap Madog (c. 1250) ap Rhiryd (c. 1215) ap Madog Ddu (c. 1185) ap Rhiryd (c. 1155) ap Llewelyn (c. 1120) ap Aldud (c. 1085) ap Owain (c. 1050) ap Edwin of Tegeingl (c. 1020).  They had a daughter:
                 Marged ferch Madog ap Ieuan, born c. 1425.  She married Ithel Fychan (c. 1415) ap Cynfrig (c. 1385) ap Bleddyn (c. 1355).  See #245 above.
 
Pen. 287, 507 cites "Madog ap Ieuan ap Gronwy Ddu" married "a daughter of Dafydd ap Gruffudd Benfras ap Gruffudd Fychan", while Pen. 131, 52 extends her ancestry as "Gruffudd Benfras ap Gruffudd Fychan ap Gruffudd ap Madog ap Rhiryd ap Llewelyn ap Owain ap Aldud".  Bartrum's charts use that construction and admit it to be a generation short; we believe one repeating pair of "Madog ap Rhiryd" was omitted in the citation, and that the descent was from Llewelyn ap Aldud, a son of Aldud missing from the pedigrees but the patriarch of several families other than this one.
 
Dwnn ii, 300 cites "Annes ferch Madog ap Ieuan ap Gronwy Ddu" married "Ithel Fychan ap Cynwrig ap Bleddyn ap Madog".  Pen. 135, 139 cites the same marriage, but calls the lady "Marged"
 
GENERATION 18:
 
270.  Ieuan ap Madog ap Ieuan, born c. 1405.
        His wife is unknown, bur he had 2 sons:
 
               John ap Ieuan ap Madog, born c. 1435.  He married a daughter (c. 1445) ferch Robert Tegin (c. 1415) ap Dafydd (c. 1385) ap Tegin (c. 1355) ap Madog (c. 1325) ap Iorwerth Goch (c. 1290) ap Ednyfed Foel (c. 1260) ap Ieuaf Fychan (c. 1230) ap Ieuaf (c. 1195) ap Llywarch (c. 1160) ap Ieuaf (c. 1130) ap Ninniaw (c. 1095) descended from Tudor Trevor.
               Madog ap Ieuan ap Madog, born c. 1435.  He married Angharad (c. 1450) ferch Madog (c. 1415) ap Llewelyn (c. 1385) ap Ednyfed Lloyd (c. 1350) ap Iorwerth Fychan (c. 1305) ap Iorwerth (c. 1275) ap Awr (c. 1240) ap Ieuaf (c. 1195) ap Llywarch (c. 1160). See this family in the next paragraph above.
 
PF ii, 351 (quoting Cae Cyriog Ms) says "Madog ap Ieuan ap Madog" married "Angharad ferch Madog ap Llewelyn ap Ednyfed Lloyd", while Pen. 132, 183 extends her ancestry as "Llewelyn ap Ednyfed Lloyd ap Iorwerth Fychan ap Iorwerth ap Awr ap Ieuaf" and Pen. 128, 167b extends that to "Awr ap Ieuaf ap Llywarch ap Ieuaf ap Ninniaw"
 
PF ii, 351 also says John was the son of Madog ap Ieuan, but the wife and son cited for John dates him to about the same year as Madog ap Ieuan; thus we make John a brother of Madog.  (Madog ap Ieuan did have a son named John, but he married another lady, she born c. 1475) The John of c. 1435 married, according to PF ii, 351, "a daughter of Robert Tegin ap Dafydd ap Tegin ap Madog ap Iorwerth Goch", and Pen. 131, 54 extends her ancestry to "Tegin ap Madog ap Iorwerth Goch ap Ednyfed Foel ap Ieuaf Fychan ap Ieuaf"; we make Ieuaf Fychan a brother of Awr mentioned in the next preceeding paragraph.
 
271.  Madog ap Bleddyn ap Einion Fychan, born c. 1400.
        He married Gwenllian (c. 1415) ferch Madog (c. 1380) ap Owain (c. 1350). See #267 above.  They had a daughter:
             
                 Mali ferch Madog ap Bleddyn, born c. 1430.  She married Llewelyn (c. 1415) ap Dafydd (c. 1380) ap Gronwy (c. 1350) ap Cynwrig (c. 1320) ap Einion (c. 1290) ap Meilyr (c. 1255) ap Gronwy (c. 1225) ap Gruffudd (c. 1195) ap Llewelyn (c. 1165) ap Cynwrig Efell (c. 1135).  The latter was a base son of Madog ap Maredudd ap Bleddyn ap Cynfyn.
 
Pen. 135, 257 cites "Madog ap Bleddyn ap Einion Fychan" married "Gwenllian ferch Madog ap Owain", while Pen. 287, 835 extends her ancestry as "Madog ap Owain ap Gronwy Sais ap Einion" and Pen. 127, 136 cites "Gronwy Sais ap Einion ap Llywarch ap Llewelyn ap Ithel Dalfrith".  Other sources incorrectly make Gwenllian the daughter of Madog ap Owain ap Gwyn ap Gruffudd ap Gronwy Sais
 
Dwnn ii, 319 cites "Mali ferch Madog ap Bleddyn ap Einion Fychan" married "Llewelyn ap Dafydd ap Gronwy ap Einion ap Gronwy ap Cynwrig ap Einion ap Meilyr ap Gronwy ap Gruffudd ap Llewelyn ap Cynwrig Efell.  That the two underlined names should be deleted can be seen by Bartrum's chart which, after dating Cynwrig ap Einion to his "generation 9", repeats generations 8 and 9 with the inserted Gronwy and Einion before continuing with Gronwy at generation 10.
 
272.  Gruffudd ap Bleddyn ap Einion Fychan, born c. 1405.
        He married Gwerfyl (c. 1415) ferch Hywel (c. 1380) ap Tudor (c. 1345) ap Gronwy (c. 1315) ap Gruffudd (c. 1285) ap Madog (c. 1255) ap Iorwerth (c. 1225) ap Madog (c. 1190) ap Rhiryd Flaidd of Penllyn (c. 1155).  He had a son and 2 daughters:
 
               Reinallt ap Gruffudd ap Bleddyn, born c. 1435.  He lived at Tower in Mold and was alive in 1465.
               Gwenhwyfar ferch Gruffudd ap Bleddyn, born c. 1440.  She married Rhys ap Robin ap Gronwy Goch, whose ancestry is unknown.
               Daughter ferch Gruffudd ap Bleddyn, born c. 1435.  She married John ap Rhys of Ial, whose ancestry is unknown.
 
Pen. 128, 617b cites "Gruffudd ap Bleddyn ap Einion Fychan" married "Gwerfyl ferch Hywel ap Tudor", while Pen. 131, 287 extends her ancestry as "Hywel ap Tudor ap Gronwy ap Gruffudd ap Madog ap Iorwerth" and Pen. 131, 99 extends that as "Madog ap Iorwerth ap Madog ap Rhiryd Flaidd"
 
Hist. Llangurig, pp 253 cites "Gruffudd ap Bleddyn at Einion Fychan" as the father of Reinallt of Tower in Mold"
 
Pen. 128, 617a cites "Gwenhwyfar ferch Gruffudd ap Bleddyn" married "Rhys ap Robin ap Gruffudd Goch" and no sources extend his ancestry further.  Bartrum would identify him as "Rhys ap Robin ap Gruffudd Goch ap Dafydd ap Madog ap Meurig ap Dafydd ap Llywarch" descended from Marchudd ap Cynan, but that Rhys was born a full generation too early to have married Gwenhwyfar.
 
The unnanmed daughter of Gruffudd ap Bleddyn appears in Bartrum's charts, but he cites no sources for her or her marriage since she was born a generation after 1400.

273.  Dafydd Lloyd ap Gruffudd ap Cadwgan Decca, born c. 1405.
        He married Gwenllian (c. 1420) ferch Llewelyn Fychan (c. 1390) ap Ieuan (c. 1360) ap Llewelyn Chwith (c. 1330) ap Cynwrig (c. 1300) ap Bleddyn Lloyd (c. 1270) ap Bleddyn Fychan (c. 1240) ap Bleddyn (c. 1210) ap Y Gwion (c. 1175) ap Radfach (c. 1145) ap Asser (c. 1115) ap Gwrgi (c. 1080) ap Hedd (c. 1050) ap Alunog of Llanfair Talhearn in Rhos.  They had a daughter:
                 Gwenllian ferch Dafydd Lloyd ap Gruffudd, born c. 1435.  She married Jenkin (c. 1420) ap Thomas (c. 1380) ap Gruffudd Benfras (c. 1345).  See #269 above for the remainder of his ancestry.
 
Pen. 176, 60 cites "Dafydd Lloyd ap Gruffudd ap Cadwgan Decca" married "Gwenllian ferch Llewelyn Fychan ap Ieuan ap Llewelyn Chwith" while Pen. 131, 57 extends her ancestry as "Ieuan ap Llewelyn Chwith ap Cynwrig ap Bleddyn Lloyd ap Bleddyn Fychan ap Bleddyn ap Gwion ap Radfach" and HLG 10b cites "Radfach ap Asser ap Gwrgi ap Hedd"
 
Pen 176, 60 cites Gwenllian as a daughter of Dafydd Lloyd and Gwenllian, and says she married "Jenkin ap Thomas ap Gruffudd Benfras"
 
274.  Gruffudd ap Belyn ap Cadwgan Decca, born c. 1420.
        He married Marged (c. 1435) ferch Rhys (c. 1405) ap Reinallt (c. 1375) ap Gruffudd (c. 1345) ap Dafydd Goch (c. 1315) ap Heilyn Fychan (c. 1285) ap Heilyn (c. 1250) ap Ieuaf (c. 1215) ap Gruffudd (c. 1185) ap Llewelyn (c. 1150) ap Owain (c. 1115) ap Aldud (c. 1085) ap Owain (c. 1050) ap Edwin of Tegeingl (c. 1020).  They had a son:
 
               Ithel ap Gruffudd ap Belyn, born c. 1445
 
Dwnn ii, 321 cites "Gruffudd ap Heilyn (Belyn) ap Cadwgan Decca" married "Marged ferch Rhys ap Reinallt ap Gruffudd", while Pen. 176, 251 extends her ancestry to "Rhys ap Reinallt ap Gruffudd ap Dafydd Goch ap Heilyn Fychan ap Heilyn ap Ieuaf ap Gruffudd ap Llewelyn ap Owain ap Aldud".
 
Dwnn ii, 321 makes Gruffudd ap Marged the parents of Ithel
 
275.  Llewelyn ap Ieuan ap Iolyn, born c. 1400
        He married Dyddgu (c. 1410) ferch Einion (c. 1375) ap Tudor (c. 1345) ap Cynwrig Moel (c. 1315) ap Cadwgan (c. 1280) ap Einion (c. 1245) ap Llywarch (c. 1210) ap Heilyn Gloff (c. 1175) ap Tyfod (c. 1145) ap Tangno (c. 1115) ap Ystrwyth (c. 1080) ap Marchwystl (c. 1050) ap Marchweithian (c. 1015) of Is Aled in Rhufoniog.  They had a daughter:
 
               Mali Llwyd ferch Llewelyn ap Ieuan, born c. 1435.  She married Hywel (c. 1435) ap Einion (c. 1405) ap Deicws Ddu (c. 1370) ap Madog Goch (c. 1335) ap Ieuan Goch (c. 1300) ap Dafydd Goch (c. 1270) ap Trahaearn Goch of Lleyn (c. 1235) descended from Collwyn ap Tangno.
 
Dwnn ii, 278 cites "Llewelyn ap Ieuan ap Iolyn ap Cynwrig" married "Dyddgu ferch Einion ap Tudor app Cynwrig ap Cadwgan ap Einion ap Llywarch ap Heilyn ap Tyfod ap Tangno"
 
The same source cites "Mali Llwyd ferch Llewelyn ap Ieuan ap Iolyn" married "Hywel ap Einion ap Deicws Ddu ap Madog ap Ieuan Goch ap Dafydd Goch ap Trahaearn Goch"
 
276.  Deio ap Edward ap Gronwy Ddu, born c. 1415.
        His wife is unknown, but he had a son:
 
                Gronwy ap Deio ap Edward, born c. 1450.  He married a daughter (c. 1460) ferch Gruffudd (c. 1425) ap Llewelyn (c. 1395) ap Ieuan (c. 1365) ap Ieuan Gethyn (c. 1335) ap Madog Cyffyn (c. 1300), who descended from Einion Efell.  Gronwy was the grandfather of Richard Davies ap Dafydd, Bishop of St David's 1560-1581
 
PF v, 94 (citing Cae Cyriog Ms) says "Gronwy ap Deio ap Edward ap Gronwy Ddu" married "a daughter of Gruffudd ap Llewelyn ap Ieuan ap Ieuan Gethyn".  Pen. 129, 51 extends his ancestry to "Ieuan Fychan ap Ieuan Gethyn ap Madog Cyffin"
 
277.  Llewelyn Fychan ap Iolyn ap Ieuaf, born c. 1395.
        He married Lleuci (c. 1400) ferch Gruffudd Goch (c. 1365) ap Ieuan (c. 1330) ap Dafydd Fychan (c. 1300) ap Dafydd (c. 1270) ap Iorwerth (c. 1235) ap Dafydd (c. 1205) ap Cowryd of Dyffryn Clwyd (c. 1175) ap Cadfan (c. 1140). 
 
Pen. 287, 540; Pen. 134, 185; Pen. 135, 110; Pen. 139(1), 93 cite "Llewelyn Fychan ap Iolyn ap Ieuaf" married "Lleuci ferch Gruffudd Goch ap Ieuan", while Pen. 129, 131 extends her ancestry as "Gruffudd Goch ap Ieuan ap Dafydd Fychan".  Pen. 131, 88 and Pen. 129, 42 continue as "Ieuan ap Dafydd Fychan ap Iorwerth ap Dafydd ap Cowryd ap Cadfan, but Bartrum shows 1 generation missing from that construction.  Dwnn ii, 237 inserts "Dafydd" between Dafydd Fychan and Iorwerth as do Harl. 2299 and 4181
 
278.  Gronwy ap Gruffudd ap Dafydd, born c. 1405.
        He married Annes ferch Gruffudd ap Ieuan Lloyd, whose ancestry is unknown.  They had a son:
 
               Dafydd ap Gronwy ap Gruffudd, born c. 1435.  He married Tangwystl (c. 1440) ferch Edward (c. 1405) ap Rhys (c. 1375) ap Gruffudd Benfras (c. 1345).  See #269 above for the rest of her ancestry.
 
Dwnn ii, 302 cites "Gronwy ap Gruffudd ap Dafydd" married "Annes ferch Gruffudd ap Ieuan Lloyd"; it further cites their son as Dafydd who married "Tangwystl ferch Edward ap Rhys ap Gruffudd" while Pen. 134, 208/209 cites "Edward ap Rhys ap Gruffudd Benfras"
 
Pen. 134, 357 calls the wife of Gronwy ap Gruffudd "Mabli ferch Gruffudd ap Ieuan Lloyd" but we have chosen the Dwnn version.
