Ancestors and Children of the Lord Rhys
                                       THE CHILDREN OF LORD RHYS
                                               By Darrell Wolcott
        The father of Lord Rhys, Gruffudd ap Rhys ap Tewdwr, had failed to reconstitute the south Wales kingdom of Deheubarth once ruled by his father, and had been forced to give fealty to King Henry I.  When he died in 1137, he held the rank and title Prince of South Wales but was only in possession of the single commote of Caeo in the eastern part of Cantref Mawr, Ystrad Tywy.  His wife, Gwenllian ferch Gruffudd ap Cynan, had been killed in 1136 as she led an army against the Normans while her husband was temporarily away in Gwynedd.  With her were sons Morgan and Maelgwn; Morgan fell in battle and Maelgwn was taken prisioner, never to be heard from again.
         Thus there were six orphan sons, aged about 2 to 22, who survived Gruffudd.  The younger boys, Rhys, Maredudd, Owain and Rhys Fychan were probably taken in by one or more of their father's former barons.[1] Anarawd was the eldest of the surviving brothers, followed by Cadell. These men set out to recover the lands over which their grandfather had ruled.  But Anarawd was killed in 1143 and, in 1152, Cadell was ambushed while out hunting in Dyfed.  He was badly injured and left for dead; while he did survive, he went on a pilgrimage to Rome and probably never recovered his health, finally passing away in 1175 after "a long infirmity".  He entrusted his lands to brothers Maredudd and Rhys, who took over the family's quest to restore Welsh rule over Deheubarth.  Maredudd died of natural causes in 1155 at the age of 25, and Rhys continued the quest alone.  Historians, with much more conjecture than evidence, claim Rhys was younger than Maredudd and thus born after 1130.[2]  We suggest he was born nearer 1123, married about 1155 and died in 1197 past the age of 70.          
          During the period 1155 until his death in 1197, Rhys proved to be a valiant warrior and skilled diplomat as he both conquered all of the original lands of Deheubarth and was so well-regarded that Henry II named him his justiciar for south Wales in 1172.  It is doubtful, however, that he was widely known as "the Lord Rhys" during his lifetime.  That epithet, likely coined by later Welsh bards is, during his lifetime, absent from the Brut...it simply calls him Rhys ap Gruffudd. 
          It seems certain that it was Rhys' intention to keep Deheubarth intact after his death and not become fragmented by the Welsh custom of equal division among his sons.  The first of those sons mentioned by the Brut was Maelgwn, who in 1187 ravaged and burned the town of Tenby in Dyfed.  One suspects it was about this time that Maelgwn learned that his father intended to make his brother Gruffudd his sole heir.  We are told that in 1189, Lord Rhys imprisoned Maelgwn in Dinefwr castle "who was then in rebellion against him".  Shortly afterwards, Gruffudd ap Rhys took his brother from the keep at Dinefwr (without his father's knowledge) and gave him over to the custody of William de Braose, the father-in-law of Gruffudd.  While Lord Rhys liberated Maelgwn in 1192, the two brothers were thereafter bitter enemies.[3]
         With this background, we now turn to the chore of identifying each of the children of Lord Rhys, who did in fact dissolve his life's work by fighting to obtain separate shares of Deheubarth.
         By his wife Gwenllian, born c. 1140, ferch Madog ap Maredudd of Powys[4], Lord Rhys had 4 sons and two daughters:
1.  Maelgwn Hen, born c. 1155.  We suggest he was the eldest son but not the choice of his father to succeed himself.  He is described as fairly short in stature with an impetious temper.  Most would make Gruffudd the eldest son since the Brut says he succeeded to the rule of Deheubarth when Lord Rhys died.  Peter Bartrum and others claim Maelgwn Hen and Maelgwn Fawr were two names for a single son of Lord Rhys by a mistress[5]. Dwnn ii, 99 lists separate men as Maelgwn Fawr and Maelgwn Hen, saying both were the offspring of mistresses.  One source[6] says "graig Maelgwn Hen ap yr arglwydd Rhys oedd Wenllian verch Madog ap Meredydd" and that "she was mam" Maelgwn Ifank mab Maelgwn Hen".  Since that lady was the wife of Lord Rhys, we think "graig" should read "mam" and "she was mam" should read "he was tad" Maelgwn Ieuanc.  Based on this flawed citation, Bartrum claims this was a base son of Lord Rhys who must have married his widow after 1197.  But his widow would have been nearing age 60 and could not have subsequently given birth to a son.  Everything we know of the Maelgwn ap Lord Rhys from the Brut is consistent with him being a legitimate son and full brother of Gruffudd. And an elder brother who was furious that his father passed him over as his sole heir, favoring Gruffudd instead.[7]  Almost immediately after their father died, Maelgwn seized Gruffudd and gave him as a prisioner to the Normans.  Maelgwn ap Rhys died in 1231; his actual wife is unknown.
2. Gruffudd, born c. 1157.  The same year Lord Rhys died, Gruffudd was captured and imprisoned by his brother Maelgwn.  In 1198, Maelgwn turned him over to the "Saxons" (read Normans).  Later that year, he was set free...likely because the Normans delighted in dividing the Welsh by setting brother against brother.  The brothers resumed their hostilities, with Gruffudd getting the upper hand until his untimely death in 1201, apparently from natural causes.  He married Maltilda (c. 1170), daughter of William de Braose, Lord of Brycheiniog.[8] He was survived by sons Rhys Ieuanc and Owain, who took up their father's feud with Maelgwn.
3.  Rhys Fychan aka Gryg, born c. 1165.  He was first noticed in the Brut in 1195 when he and his brother Maredudd took the castle at Dinefwr.  He battled against his nephews, the sons of Gruffudd, for several years...sometimes as an ally of Gwynedd's Llewelyn Fawr and sometimes siding with King John.  In 1213, he was placed in the king's prison but released in 1215 after giving his son Rhys Fychan as a hostage.  Thereafter, he was called Rhys Gryg and his son later become known as Rhys Mechyll who also named a son Rhys Fychan, usually called Ieuanc.  He married (a) Joan, daughter (c. 1180) of Earl Richard de Clare [9]; (b) Ellyw (c. 1170) ferch Trahaearn ap Gwgan ap Gwgan ap Bleddyn ap Maenyrch[10]; and (c) Gwenllian (c. 1165) ferch Elidyr ap Owain ap Idnerth ap Cadwgan ap Elystan Glodrydd.[11]  Rhys Gryg died in 1233.
4.  Maredudd Gethin, born c. 1170.  After assisting his brother Rhys take Dinefwr in 1195, the Lord Rhys seized both sons and placed them in his prison. While Rhys Gryg was released when his father died, nothing more is heard about Maredudd until he was killed in battle in 1201.  He is said to have married Gwenllian Fychan (c. 1185) ferch Sir Hywel ap Iorwerth ap Owain Wan of Caerleon in Gwent[12]. He left a daughter, Gwenllian[13], and a son, Gruffudd[14].
5.  Marged ferch Lord Rhys, born c. 1169.  She married Gwenwynwyn (c. 1155) ap Owain Cyfeiliog[15] of southern Powys about 1182.  Nothing more is known of her, but she was the mother of Gwenwynwyn Cyfeiliog. [16]
6.  Gwenllian ferch Lord Rhys, born c. 1180.  She married Ednyfed Fychan (c. 1165) the seneschal of Llewelyn Fawr of Gwynedd.  Her death is recorded in 1236[17].  Most sources claim she also married Rhodri ap Owain Gwynedd, but we believe that was a different lady whose name was probably Annes. (see below)
           Children of Lord Rhys by various mistresses were:
7.  Maelgwn Fawr, born c. 1150.  His mother was Gwerfyl (c. 1135) ferch Llewelyn ap Rhys ap Morda Frych ap Cydrich ap Gwaithfoed of Cantref Bychan[18].  Some sources claim he married Gwenllian, his step-mother, the wife of Lord Rhys.  That lady was a half-generation older than Maelgwn Fawr and would have been about 57 years old when Lord Rhys left her a widow.  Those sources also say this couple were the parents of Maelgwn Ieuanc.  However, the deeds of Maelgwn Ieuanc appear to identify him as a son of Maelgwn Hen and born during the lifetime of Lord Rhys.  This base son, also called Maelgwn, is probably wholly absent from the Brut and may have been called "Fawr" simply to describe him as a man large in stature, or because he was the eldest of Lord Rhys' sons.  The Brut never calls its Maelgwn ap Lord Rhys by any nickname; we arbitrarily call the legitimate Maelgwn "Hen" since he had a son Maelgwn Fychan or Ieuanc (the younger).  Accordingly, we think Lord Rhys had both a base son and a legitimate son named Maelgwn, but nothing except the name of his mother is known about the base son. The fact that his mother was a near neighbor of Lord Rhys' paternal home in Caeo argues for this child to have been conceived before his marriage.
8.  Maredudd Ddall (the blind), born c. 1157.  He was, as a child, given to King Henry II as a hostage to insure the fidelity of Lord Rhys.  When Rhys joined the other Welsh princes in rebellion and defeated the king's army at Corwen in 1165, an angry Henry II had the boy blinded and sent back to his father.  His mother was Gwenddydd ferch Cynddelw ap y Bochawc of Emlyn[19], but one source[20] says Cynddelw ap Brochwel.  Her further ancestry is unknown.  This Maredudd was a natal brother of Tangwystl mentioned below[21].  He lived a long, but uneventful life, dying in 1239.
9.  Cadwaladr Lwgr, born c. 1158.  He is often identified as the son born of a niece of Lord Rhys, whom we call Meurig (see below).  But Cadwaladr's obit is recorded in 1186 and he left a son, Einion ap Cadwaladr of Brycheiniog[22], so he could hardly be the son born in 1173.
10.  Owain, born c. 1159.  His mother is cited as Isabel ferch Iorwerth Fodrychan[23] and as Sabel ferch Ivan Hir[24], neither of which has been further identified.  He received lands in Caerwedros, Ceredigion and died in 1191, leaving a son named Maredudd. His wife is unknown.
11.  Maredudd, born c. 1160.  His mother was a daughter (c. 1145) ferch Dafydd Fras ap Rhydderch, descended from Owain ap Dyfnwal, king of Strathclyde. [25].  He was appointed Archdeacon of Ceredegion and dedicated his life to the church, dying in 1227. His wife is not cited, but children are assigned to him.
12.  Hywel Sais, born c. 1165.  His mother was Ystedur (c. 1140) ferch Caradog ap Llawrodd Dyfed ap Gwynfardd Dyfed[26].  This lady is called a "foster sister" of Lord Rhys since, as an orphaned child, Lord Rhys had been reared by Caradog.  Hywel was given as a hostage to King Henry II when yet a child, but was released back to his father in 1171.  In 1175, Lord Rhys hoped to curry favor with the king and sent Hywel to serve Henry II while the latter was attending to his lands in France.  After returning from that assignment, he was dubbed "Sais" because he could speak the language of the "Englishmen".  He held lands in Dyfed where he took the castle of Wizo the Flemish man in 1193.  The following year, in an attempt to control his rebellous sons, Lord Rhys attacked Hywel Sais and Maelgwn in Dyfed but was captured by those sons.  Without the knowledge or consent of Maelgwn, Hywel Sais set their father free.  In 1204, Hywel Sais was killed by Maelgwn's men.  He left behind three sons: Cynan, Madog and Rhys and a daughter, Angharad.  His wife is unknown.
13.  Cynwrig, born c. 1165.  His mother was Nest (c. 1150) ferch Gruffudd ap Gwyn ap Gwalchmai ap Cydrich ap Gwaithfoed of Cantref Bychan[27].  Her brother, Cadifor, and his 4 sons were captured and slain by Maelgwn ap Lord Rhys in 1205.  Cynwrig met Gerald of Wales during his 1188 Journey Through Wales, who described him as tall, handsome and with fair curly hair.  Gerald preached a sermon to Lord Rhys and his sons Maelgwn, Gruffudd and Cynwrig but none of them elected to "take up the cross" when implored to do so[28].  One version of the Brut claims Cynwrig was also blinded with his brother Maredudd, but the text was corruptly translated.[29]  He was in fine spirits and leading a small warband of "lightly armed young men" when Gerald encountered him in 1188.  In his 1978 translation of Gerald's Tour, Lewis Thorpe footnoted Cynwrig as Lord Rhys' third son, probably because only 3 sons met with Gerald[30]. 
14.  Morgan, born c. 1170.  His mother is cited as Nest ferch Caradog Fychan ap Caradog, but her further ancestry is not known. [31] This Morgan served as penteulu for his half-brother Gruffudd during the period 1198 to 1201.  He died in 1251 of old age at Strada Florida.  No issue is known.
15.  Meurig, born in 1173.  His mother was Gwenllian (c. 1155) ferch Maredudd ap Gruffudd ap Rhys ap Tewdwr[32], thus a daughter of Lord Rhys' brother.  She was likely a base daughter, possibly born posthumously since her father died in 1155 at age 25.  He is the only son of Lord Rhys whose date of birth is recorded in the Brut, probably because the cleric who wrote the entry for 1173 wished to emphasize the incestual nature of the relationship between Lord Rhys and this Gwenllian. Most historians say he is the same man as Cadwaladr Lwgr mentioned earlier, but offer nothing credible to overrule the earliest source.  Nothing is known of Meurig save his birth.
16.  Rhys Gochyn, born c. 1175.  This man in known only from the medieval pedigree manuscripts, where his son Rhys Goch (c. 1205) is cited as the husband of Gwen (c. 1220) ferch Angharad (c. 1200) ferch Hywel Sais[33].  This Gwen was a daughter of his (Rhys Goch's) first-cousin who had married a grandson of Sir Roger of Powys[34].
17.  Catryn, born c. 1151.  This lady was given as wife to Cadifor ap Dyfnwal[35], a warrior for Lord Rhys who, it is said, took the castle at Cardigan by scaling its walls in 1164. Cadifor was born c. 1140.
18.  Unnamed daughter, born c. 1155.  She married Lucas de Hoda of Cemais[36], a Norman knight born c. 1145 said to be a follower of Martin of Tours.  Her mother is unknown, and she might have been the same lady as one of Lord Rhys' known daughters.
19.  Unnamed daughter, born c. 1158.  The Brut entry for 1175 lists several men whom Lord Rhys took to the king's council in Gloucester because they had incurred the king's displeasure.  One man is identified as "Einion ap Rhys, his other son-in-law, of Gwerthrynion".  Probably descended from the clan of Elystan Glodrydd, this Einion is not further identified nor is his wife named.  Since that daughter was already married in 1175, she could not have been born much later than 1160.  But she might have been the same lady as one of his base daughters whose name we know and who later married a second husband.
20.  Susanna, born c. 1160.  She married Einion of Porth (c. 1150) ap Einion Clud ap Madog ap Idnerth ap Cadwgan ap Elystan Glodrydd. He was another of the men Lord Rhys took to the king's council in 1175 and described as "Einion Clud (sic), his son-in-law, of Elfael."  But Gerald of Wales, in his 1188 journey, says "next came Einion, son of Einion Clud, prince of Elfael....who spoke to Rhys who was present and whose daughter he had married.."[37].  While neither early source gives this daughter's name, she is called Susanna in a c. 1280 tract[38].  Again, the lady could not have been born later than c. 1160 as she was already married in 1175.  Her mother is unknown.
21.  Tangwystl, born c. 1165.  She had the same mother as Maredudd Ddall[39], the only known instance where Lord Rhys had two base children by the same mistress.  It is possible that after the lady's son had been blinded, Lord Rhys determined to give her another child; it had been his behavour which caused King Henry II to blind her son while held as a hostage.  She married (1) Maredudd (c. 1155) ap Rhydderch ap Bledri Latimer ap Bledri ap Cadifor Fawr[40]; and (2) Einion (c. 1155) ap Llywarch, further ancestry uncertain. [41]  While we assign both marriages to a single lady, it is not impossible that Lord Rhys had two daughters both named Tangwystl.
22.  Angharad, born c. 1169.  She married William fitz Robert fitz Martin of Cemais[42].  He died in 1209 and was born c. 1155. A descendant of Angharad and William was David Martin, Bishop of Mynyw from 1296 to 1328.  Her mother is unknown.
23.  Lleuci, born c. 1170. She married Owain Foel (c. 1155) ap Caradog ap Owain Fab ap Rhydderch ap Tewdwr [43].  Her mother is unknown.
24.  Annes, born c. 1170.  According to Gerald of Wales, when he met Rhodri ap Owain Gwynedd in 1188, "only a short time before Rhodri had taken the daughter of Prince Rhys as his mistress". Gerald did not name the lady[44].  Some medieval genealogists[45] say it was Gwenllian ferch Lord Rhys and that she was married to Rhodri before she married Ednyfed Fychan.  We suggest Gwenllian, who married Ednyfed Fychan about 1195, was under 10 years of age in 1188 and would prefer the source which calls the mistress of Rhodri "Annes"[46].  And we suspect Rhodri, born c. 1145, already had sons her age in 1188, by an unknown wife. One source, which calls this daughter "Gwenllian", says she was the "graig" (wife) of Cynan ap Rhodri[47].  While that is chronologically impossible, she may have been the mother of Cynan.[48] 
25.  Gwladys, born c. 1180.  She married Hen William Caentwn, also called William Cantington and William Canton[49].  He was born c. 1170 and his obit is recorded in the Brut in 1230 as William Canton.  Her mother is unknown. 
           Others mentioned as children of Lord Rhys include a son Cadwgan[50] which is probably an error for Cadwaladr; daughters Elinor[51] and Marged[52] who, by their marriages, must have been born before the year 1100 and might have been children of Rhys ap Tewdwr; (NOTICE: See updated information in APPENDIX below) and a daughter Gwenllian mentioned in the Brut in 1190 as dying that year "the flower and beauty of all the women of Wales".  This might have been Gwenllian the wife of Lord Rhys; it is difficult to explain the praise given the lady in her obit should she have been just another base daughter of Lord Rhys (the Gwenllian who was born in wedlock did not die until 1236).  This is particularly true if the daughter we call Annes, but others call Gwenllian, was actually named Gwenllian.  It seems incredulous that such a lady, a mistress of Rhodri ap Owain Gwynedd and in an incestious relationship (Lord Rhys and Rhodri were first-cousins), would merit such praise from the cleric who penned the Brut entry.
         All the estimated birthdates which we list are merely our guesses based on (1) the probable birthdate of their mother, or (2) the likely birthdate of their spouse, or (3) events recorded in the Brut in which they participated.  Neither these dates, nor the order in which we list the children, should be taken as more than "probable".
         The possibility that one or more of those children in our list is the same person (under a different name) cannot be excluded. Pedigrees abound where females are called by differing names, depending on the source[53]. A daughter whose husband died early almost certainly could be expected to wed another.  In addition, those 4 names mentioned at the end of our list might have been children of Lord Rhys if we assume that incorrect spouses were cited for two of those ladies. (See APPENDIX below)  Accordingly, there can be no definitive answer to the question "how many children did Lord Rhys have?"

[1] Pen. 131, 209 says that Caradog ap Llawrodd of Dyfed was the foster father "dad maeth" of Lord Rhys and the natal father of Ystedur, the mother of Hywel Sais ap Lord Rhys
[2] Dictionary of Welsh Biography p. 838 says Lord Rhys was younger than his brother Maredudd and born in 1132.  This conjecture appears solely based upon the obit notice in the 1155 Brut entry which described Maredudd as "lord of Ceredigion and Ystrad Tywy and Dyfed", and the fact that, in 1153 when Cadell ap Gruffudd turned his lands over to his brothers, the name of Maredudd preceeds that of Rhys. In fact, the 1153 entry makes the brothers co-lords and the choice of listing their names in alphabetical order is very thin evidence on which to base a filial order.  The marriage of Lord Rhys to a lady born c. 1140 and having sons born c. 1155/57 argues for his birthdate c. 1125, as does his first appearance as a warrior in 1146.

APPENDIX:   (Results of new research in May, 2023)
        Elinor ferch Lord Rhys was born c. 1160 and she married Moriddig (1145) ap Drymbenog (1110) ap Maenyrch (1075) ap Dryffin (1047) which Dryffin was a brother of King Bleddyn ap Maenrych of Brycheiniog.
       Marged ferch Lord Rhys was born c. 1160 and she married Cadwgan (1145) ap Drymbenog (1110) ap Maenyrch (1075) of the same family line mentioned immediately above.
       This Brycheiniog family is further examined in our paper found at the following link:
