THE CLAN OF TUDOR TREVOR
By Darrell Wolcott
Seated on the northern march
of Wales just south of Chester, this family represents a junior branch of the first Royal Dynasty of Powys. While careless
genealogists equate the Cadell who sits atop its pedigree with the fifth century Cadell Ddyrnllwg, this family actually split
from the royal line about the start of the seventh century. We believe its Cadell was the "King Cadell" who fell
at the Battle of Chester, probably a son of Cynan Garwyn and younger brother of Selyf.
The traditional history of Wales (a
mixture of fact and legend) as it affects this family is outlined by Edward
Hamer in his "A Parochial Account of Llangurig". The following statements are extracted from that account,
with our comments in italics following each paragraph:
Ynyr was Lord of Chirk,
Whittington, Oswestry, Maelor Cymraeg and Maelor Saesnaeg in Powysland, being the son of Cadfarch ap Gwrgeneu. In the
year 870, he built the castle of Whittington. By his wife Rhiengar, daughter and heiress of Lluddoca ap Caradog Freichfras,
Lord of Hereford, Gloucester, Erging and Ewias, Ynyr had a son Tudor called Trevor for his birthplace. In 907, Tudor
Trevor married Angharad, daughter of Hywel Dda. He had three sons:
(Our timeline for this family
would place the birth of Ynyr at c. 870. He may have resided at Whittington but the castle was still over 150 years in the
future for Wales. The first stone castle at Whittington was built on the site of an earlier hill fort in the 13th
century. The Caradog Freichfras who was grandfather to Rheingar was the ninth century man of Rhos in north Wales,
not the sixth century same-named man of Ewias. We date the birth of Tudor Trevor c. 900 and his
marriage would have occurred c. 928/930)
(1) Gronwy, who died in his father's lifetime, married Tangwystl,
daughter of Dyfnwal ap Alan ap Alser ap Tudwal Gloff ap Rhodri Mawr, by whom he had an only daughter and heiress, Rhiengar
who succeeded to her grandfather's lands in Hereford, Gloucester, Erging and Ewias. She married Cyhelin ap Ivor ap Seferus,
Lord of Buillt, Radnor, Ceri, Maelienydd, Elfael and Cydewain. By Cyhelin, she was the mother of Elystan Glodrydd,
Prince of Fferllys. He was born in 927 and was named after King Athelstan who was his godfather. He was living
in 1010 but slain in a civil broil in Montgomeryshire.
(Tangwystl was the daughter of Dyfnwal
ap Alser ap Tudwal Gloff; since her father died in the lifetime of Tudor Trevor, she would inherit nothing from
either man under Welsh law. And Tudor Trevor did not hold any land south of Oswestry anyway.
Elystan Glodrydd was born near 985/990 long after the death of King Athelstan, and likely died nearer 1050/1060.)
(2) Lluddoca was Lord of Chirk, Whittington, Oswestry
and Maelor Saesnaeg and died in 1037, leaving by his wife Angharad (daughter of Iago ap Idwal of north Wales) a son Llywarch,
who by Lucy his wife, daughter of Gwerystan ap Gwaethfoed, Lord of Cibwyr in Gwent, had a son and heir, Ednyfed, who married
Janet, daughter of Rhiwallon ap Cynfyn and was the father of Rhys Sais.
(Lluddoca was likely born
c. 930/935 and his obit is not recorded. Angharad would have been a granddaughter of Idwal Foel, not a daughter
of King Iago ap Idwal whose rule began in 1033. The Lleuci who married Llywarch Gam was a daughter of Gwerystan, but he
had no connection at all with lands in Gwent. His home was probably Cwybr in Tegeingl. The Sioned
(Janet) who married Ednyfed was a daughter of Rhiwallon ap Dyngad ap Tudor Trevor, not Rhiwallon ap Cynfyn.
(3) Dyngad, Lord of Maelor Cymraeg married Cecilia,
daughter of Seferus ap Cadifor, Lord of Buillt and had a son, Rhiwallon who died in 1040 and left by his wife Letitia, daughter
of Cadwalar ap Pereder Goch of Mon, a son Cynwrig who succeeded his father as Lord of Maelor Cynraeg. Cynwrig
was slain in 1074 during an incursion of the Danes into Maelor. By his first wife Judith, daughter of Ifor Hen of Rhos,
he had five sons: Ninniaw, Ednyfed, Gruffudd, Bleddyn and Hoedliw. Cynwrig married secondly Annesta, daughter
of Idnerth Benfras, Lord of Maesbrook, by whom he had seven more sons: Dafydd, Hwfa, Llewelyn, Einion, Iorwerth, Ieuaf and
Bledrws and one daughter, Jane who married Madog ap Cadwgan of Nannau and had issue a son Rhiwallon.
(Rhiwallon ap Dyngad would date from c. 965
but his obit is not recorded. The lady mentioned as his wife was born c. 1145 and married a later Rhiwallon of this family.
Cynwrig ap Rhiwallon ap Dyngad was born c. 995 and was definately not the man of that name reported slain in 1075 not in Maelor
but in Lleyn (Gwynedd). The present Cynwrig did not marry Dyddgu (Judith) ferch Ifor Hen of Rhos; that lady dates
from c. 1075 and married a later Cynwrig ap Rhiwallon. He likely did marry a daughter of Idnerth Benfras of Maesbrook,
but their only known sons were Dafydd and Rhiwallon. The other sons listed in the account were children of much later men,
as was the daughter Sian (Jane).
this family's early generations would look like this:
GRONWY ap TUDOR:
820 Rhodri Mawr
Cadell Tudwal Gloff 865

Hoedliw 1105 1110 Hwfa
1135 Einion 1130
Rhiwallon===Letitia ap Cadwaladr
l ap Peredur 1145
of other early families might be helpful to frame the chronology on which our birthdate estimates are based:
TEGONWY ap TEON of Cegidfa, Powys:
765 Iorwerth Hirflawdd
Lles Llydog 860
Gwynnog Farfsych 890
930 Dyngad ap 960 Cuhelyn
Tudor Trevor =
ap Tudor Trevor 965 Llywarch Gam ap
PEREDUR of MON:
1115 Angharad===Owain 1100
of the 3rd
We did not carry this family back beyond the men cited in ABT 2g where Angharad ferch Peredur is called the mother of Cynan
ap Owain Gwynedd, but it is an old line descended from Meirion ap Cunedda. See the paper "Bradwen of Llys Bradwen in
Just as earlier
names were repeated in the family branch descended from Dyngad (in which three different men named Cynwrig ap Rhiwallon have
been rolled into one by early historians), the same thing obscures the family descended from Llyddoca. Rhys Sais of
c. 1025 appears to have named sons Tudor and Elidyr (but probably not Iddon as many claim) Tudor had sons, Bleddyn
and Gronwy, while Bleddyn's son Rhys is also called Rhys Sais. That man, born c. 1115, had sons Iddon, Tudor and Elidyr.
And both the latter men named a son the same as the earlier brothers: Bleddyn ap Tudor and Meilyr ap Elidyr. In chart
form, we find:
1025 Rhys Sais I
1085 Bleddyn 1090 Gronwy Meilyr
1124 Rhys Sais II
1152 Elidyr 1153 Iddon
Cadwgan Gruffudd Madog Iorwerth Ednyfed
1210 1215 1215 1215
Rhys Sais of c. 1025 married his first cousin,
Efa ferch Cynwrig ap Rhiwallon; Cynwrig was the brother of Rhys' mother, Sioned. Tudor ap Rhys Sais married a Sioned
ferch Rhiwallon. Chronologically that lady may have been a daughter of Rhiwallon ap Cynfyn born c. 1065 or a daughter
of Rhiwallon ap Cynwrig ap Rhiwallon ap Cynwrig ap Dyngad, a lady who would also occur near 1060. If the latter, she
would have been a first cousin of Tudor but original sources are lacking. We prefer the first listed possibility.
Bleddyn ap Tudor of c. 1085 married
a lady born c. 1095, Annes ferch Llewelyn ap Idnerth ap Cadwgan ap Elystan (of Powys, not Elystan Glodrydd of Buellt
and Fferlys). Bleddyn's brother Gronwy was the father of Sir Roger and Jonas having wed the mother of three Peverel
siblings. And Bleddyn began a repeating naming cycle by calling a son Rhys known as Rhys Sais II. That man
married a granddaughter of Rhys ap Tewdwr, Efa ferch Gruffudd ap Rhys born c. 1130. Rhys Sais II of c. 1124 named
sons Tudor, Elidyr and Iddon. This Tudor had a Bleddyn while his brother Elidyr named a son Meilyr. Although
Meilyr followed his earlier namesake by calling one son Gruffudd, his eldest son was the Cadwgan who is called Lord of Eyton.
Fortunately, the Bleddyn ap Tudor of c. 1185 did not continue the naming repetition, calling his only known son Owain.
Due to the proximity of their
lands to the Saxon kingdom of Mercia, the family descended from Llyddoca ap Tudor Trevor had established amicable relations
with their neighbor to the east; it is believed the first Rhys Sais became fluent in the Saxon language and served the Earl
of Mercia as latimer or interpretor. Thus his nickname "Rhys the Englishman". Apparently his son Tudor and grandson Bleddyn
served in the same capacity for the Norman Marcher Lords, the Earls of Montgomery. It was during the lifetime of the
first Rhys Sais that the majority of his lands (all but Nanheudwy which, among his holdings, lay the furthest west) were detached
from Powys to become a part of the Norman shire Salop (now Shropshire).
 HLG 12 and ABT 9b make Tudor Trevor "ap Ynyr ap Cadfarch ap Gwrgeneu ap Gwaeddgar
ap Bywyn ap Biordderch ap Gwriawn ap Gywnnan ap Gwnfyw Frych ap Cadell" and continue with the ancestry of Cadell Ddyrnllwg
of c. 380. But the Cadell in this list would occur c. 580.
 The Annals of Inisfallen, an 11th century Irish source, reports the Battle
of Chester under the date 614 and says both Selyf ap Cynan "king of the Britons" and "king Cadell" were killed. The
Welsh Annales Cambriae record of the battle notes the death of Selyf but not of Cadell. We suggest Selyf was the Welsh
commander at the battle, while Cadell was "king" of a subordinate territory...probably of the lands at the site of the battle.
Both men would date from c. 575/580.
 Montgomeryshire Collections, vol ii, pp 225-300
 See the paper on this site entitled "Ynyr Gwent and Caradog Freich Fras"
for a discussion of the two different men called Caradog Freichfras.
 See the paper on this site entitled "Llowarch ap Bran - Lord of Menai" for
the correct pedigree of Tangwystl ferch Dyfnwal.
 The claim that this granddaughter of Tudor Trevor inherited his lands
around Hereford, Gloucester and Ewias was apparently concocted to explain why no such holdings are found among his descendants.
But the mother of Tudor Trevor wasn't descended from the Caradog Freich Fras who did hold land in those areas; any land she
may have inherited would have been in far north Wales.
 The likely home of Gwerystan is discussed in the paper "Ithel of Bryn
in Powys" elsewhere on this site.
 Rhiwallon ap Cynfyn was born to Cynfyn and Angharad ferch Maredudd shortly
after the 1023 death of her first husband. No daughter of his could have married an Ednyfed born c. 995 or have
borne Rhys Sais near 1025.
 The Welsh Chronicles report for 1075 says "Cynwrig ap Rhiwallon was slain
by the men of Gwynedd" while the author of "Historia Gruffudd ap Cynan" asserts that Cynwrig was a co-usurper of Gwynedd with
Trahaearn ap Caradog and was slain in Lleyn by men loyal to Gruffudd. Those historians who equate that Cynwrig with
the son of Rhiwallon ap Dyngad would have us believe a man about 80 years old had been selected as a co-ruler of Gwynedd
following the death of Bleddyn ap Cynfyn. Others would identify the 1075 Cynwrig as a son of Rhiwallon ap Cynfyn and
have us believe it was a lad about 21 years old who ruled in Lleyn. Our choice for his identification is a son of Rhiwallon
ap Gwyn and first cousin of his co-ruler Trahaearn ap Caradog ap Gwyn.
 A possible identification and dating of this man is the subject of
the paper entitled "Idnerth Benfras of Maesbrook" elsewhere on this site.
 For the possibility this Gronwy had a base son by a Saxon lady, see
the paper entitled "The Mysterious Peverel Family" elsewhere on this site.
 This man was father to the "Tuder Walensis" cited in the 1086 Domesday
Book as the holder of land in Whittington under Earl Roger de Montgomery
 J.Y.W. Lloyd's "History of Powys Fadog" vol 2, pp 117 says
this marriage is cited in his source manuscripts, which he identifies as the Cae Cyriog Ms and Harleian Ms 4181. Our
dating of Ifor Hen to c. 1045 relies on conjecture as to who was his father. But as Lord of Rhos, we place him two generations
after Gwrydr Goch ap Heilig; Gwyrdr Goch was born c. 985 and inherited Uwch Dulas in Rhos and other land in Rhufoniog
while his brother received Is Dulas in Rhos.
 Under the 1081 entry in the Brut, we are told that Gwrgeneu ap Seisyll was
slain by "the sons of Rhys Sais". In his "History of Powys Fadog, vol ii, pp 152, Lloyd claims those sons were Elidyr,
Tudor and Iddon. There is no evidence the sons living in 1081 had a brother named Iddon; the Iddon ap Rhys Sais found
in the old pedigrees dates from c. 1153. Rhys Sais II of c. 1124 is the only man of that name known to have had
sons named Elidyr, Tudor and Iddon.
 Burke's "Landed Gentry", under the family of Lloyd-Davis of Whittington,
identifies the wife of Tudor as Janet (Sioned) daughter and co-heir of Rhiwallon ap Cynfyn. We see no good reason to seek
a different Rhiwallon as her father.
