Mistress (1): TANGWYSTL, daughter of LLYWARCH "Goch" of Rhos & his wife ---. 

Prince Llywelyn had one illegitimate son by Mistress (1): 

4.          GRUFFYDD (before 1205-Tower of London 1 Mar 1244).  Called "frater primogenitus" of David by Matthew of Paris, when he records that Gruffydd consented to his brother's succession on the death of their father.  Lord of Lleyn.  He was captured and imprisoned in the Tower of London, dying in an escape attempt. 

Mistresses (2): - (7): ---.  The names of the other mistresses of Prince Llywelyn are not known. 

Prince Llywelyn & his second wife had three children:

1.         DAFYDD ([1208]-25 Feb 1246, bur Aberconway).  Son of Llywelyn according to Matthew of Paris.  The Annales Cambriæ name "David filius eius [Lewelini] de Johanna filia Johannis regis Angliæ".  Henry III King of England granted protection to "nepotem nostrum David filium…L. principis Norwallie" dated [May] 1229.  Henry III King of England granted safe passage to "David filium L. principis Norwallier in veniendo ad regem ad faciendum ei homagium suum, et sororem ipsius David" dated 5 Sep 1229.  He succeeded his father in 1240 as DAFYDD II Prince of Wales.  The Annales Cambriæ record the death in 1246 of "David filius Lewelini apud Aber" and his burial "apud Aberconuy".  The Chronicle of the Princes of Wales records that "David son of Llywelyn died at Aber in the month of March and was buried with his father at Aberconway" in 1246.  The Annales Cestrienses record the death “V Kal Mar” 1246 of “David fil. Lewelini princeps Wallie” and his burial “apud Abercon juxta patrem suum”.  m (1230) ISABEL de Briouse, daughter of WILLIAM de Briouse & his wife Eva Marshal of the Earls of Pembroke (-1248).  A letter from "L. princeps de Aberfrau, dominus Snauedoniæ" to "E. de Braus", dated [May] 1230, enquires whether she wishes the proposed marriage between "David filium nostrum et I. filiam vestram" to take place.  A manuscript which narrates the descents of the founders of Lanthony Abbey names “Isabella, Matildis, Eva et Alianora” as the four daughters of “Willielmus de Brews quartus” and his wife “Evam filiam domini Willielmi Mareschalli”, adding that Isabel married “David filio Lewelini principis Walliæ”.  The Annals of Dunstable record that “Willelmus de Brause…filiam suam” married “Leulino…filio”, with as her dowry “castello de Boet”, which reverted to her family after her husband died. 

2.         HELEN (-1253 before 24 Oct).  The Annales Cestrienses record in 1222 that “Johannes filius comitis David” married “filiam Lewelini” in accordance with the agreement between him and “comitem Cestrie”.  The Annals of Dunstable record that “Johannes comes Cestriæ” died in 1237 and “eius uxor…filia Lewelini” married “Roberto [de Quinci]” against her father´s wishes.  The primary source which confirms her name has not yet been identified.  Matthew of Paris records that it was suspected that his wife "filia Leolini" poisoned John “the Scot”.  A writ after the death of "Eleanor, sometime the wife of John Earl of Chester", dated "the eve of St Martin 38 Hen III", records the "partition of her lands between Si J. de Bayllol, Robert de Brus, and Henry de Hasting, the heirs of the said earl".  m firstly ([1222]) JOHN "the Scot" Earl of Huntingdon, son of JOHN of Scotland Earl of Huntingdon & his wife Matilda of Chester ([1207]-Darnal [5/7] Jun 1237, bur Chester St Werburg).  He was created Earl of Chester 21 Nov 1232.  m secondly (1237 before 5 Dec) ROBERT de Quincy, son of SAHER Earl of Winchester & his wife Margaret of Leicester (-Aug 1257). 

3.         SUSANNA ([1216/21]-after 24 Nov 1228).  Henry III King of England granted the upbringing of "L. princeps Norwallie et Johanna uxor sua et…soror nostra Susannam filiam suam" to "Nicholao de Verdun et Clementie uxori sue" by order dated 24 Nov 1228.  Her birth date is estimated on the assumption that Susanna was under marriageable age, but older than an infant, at the time. 

Prince Llywelyn had five illegitimate children by Mistresses (2) - (7):

5.          GWENLLIAN (-1281).  In his report to King Henry dated 5 Aug 1224 following the capture of castle Trum, William Marshall Earl of Pembroke records that "the wife of William de Lascy, the daughter of Llewllyn, Griffin´s sister, the wife of Thomas Blund, William´s brother, and the mother of William, of Thomas, and of him that was killed" were in the castle.  m WILLIAM de Lacy, son of HUGH de Lacy & his second wife Rose --- (-killed in battle Monach-cranncain 1233). 

6.          GWLADUS Ddu ("the Black") (-Windsor 1251).  The Annals of Dunstable record that “Reginaldus frater eius” (referring to “Ægidius Herefordensis episcopus”) married “Leulini Regis Walliæ…filiam” in 1216.  Henry III King of England granted protection to "Gwladosa filia…[L.] principis [Norwallie] que fuit uxor Reginaldi de Brausa" dated [May] 1229, issued at the same time as letters of protection to her brother David.  Henry III King of England granted safe passage to "David filium L. principis Norwallier in veniendo ad regem ad faciendum ei homagium suum, et sororem ipsius David" dated 5 Sep 1229.  It is likely that this unnamed sister of David was Gwladus, coming to England with her brother before her second marriage.  The Annals of Worcester record that “Radulphus de Mortuomari” married “filiam Lewelini, conjugem quondam Reginaldi de Breusa” in 1230.  A manuscript narrating the foundation of Wigmore Abbey records that “Radulphus” married “Lewelinus princeps…Gwladusam Duy filiam suam”, who brought her husband “omnibus terries de Kery et Kedewyn”.  The Annales Cambriæ record the death in 1251 of "Gladus filia domini Lewelini" at Windsor.  m firstly ([1215/16]) as his second wife, REYNOLD de Briouse, son of WILLIAM [III] de Briouse & his wife Mathilde de Saint-Valéry Dame de la Haye (-[5 May 1227/9 Jun 1228]).  He succeeded in 1215 as Lord of Abergavenny.  m secondly (1230) RALPH [II] de Mortimer of Wigmore, son of ROGER [III] de Mortimer & his [second] wife Isabel de Ferrers (-6 Aug 1246, bur Wigmore). 

7.          MARGARET (-1272 or after, bur [Acornbury Priory, Herefordshire]).  The Chronicle of the Princes of Wales records that "John de Bruse married Margaret the daughter of Llywelyn son of Iorwerth" in 1219.  "Katerina de Lacy filia Walteri de Lacy" donated land in Cofham, held by "domino Waltero de Clifford", to Acornbury priory, Herefordshire, for the souls of “fratris mei…et…dicti Walteri de Clifford et Margaretæ uxoris suæ et Margaretæ filiæ ipsius” by undated charter, witnessed by "domino Willielmo de Evereus, domino Rogero de Clifford, domino Ricardo Tirel, domino Roberto de Lacy, domino Willielmo de Rachesford…".  "Walterus de Clifford filius Walteri de Clifford et Agnetis de Cundy" donated land in Cofham to Acornbury priory, Herefordshire, also donated by "Katherinæ filiæ Walteri de Lacy", for the souls of “Margaretæ uxoris meæ et dominæ Mathildis filiæ meæ” by undated charter.  "Margareta quondam uxor domini Walteri de Clifford" elected burial at Acornbury priory, Herefordshire by charter dated “tertia die dominica proxima ante festum sancti Thomæ apostoli” in 1260, witnessed by "…Henrico de Clifford…".  m firstly (1219) JOHN de Briouse Lord of Bramber and Gower, son of WILLIAM de Briouse & his wife --- (-1232).  m secondly WALTER [III] de Clifford of Clifford Castle, Herefordshire, son of WALTER [II] de Clifford & his wife Agnes de Cundy (-Dec 1263). 

8.          ANGHARADm MAELGWN ap Maelgwn "Fychan" Lord of Ceredigion [Cardigan], son of MAELGWN ap Rhys Lord of Ceredigion & his wife --- (-1257). 

9.         SIC - It is more likely that this Helen is the daughter of Llywelyn’s son, David, based on the dates of her marriage to Donald, and the birth years of their children.

[HELEN] (before [1230]-after 16 Feb 1295).  John of Fordun´s Scotichronicon (Continuator) records the death in 1228 of "Malcolmus comes de Fyfe" and the succession of "Malcolmus nepos eius, filius…fratris eius", adding that the latter later married "filiam Leulini regis Walliæ".  The Chronicle of Melrose records the death in 1230 of "Malcolm earl of Fife" and the succession of "his nephew Malcolm, the son of his brother", adding that the latter "afterwards married the daughter of Leulin".  The Chronicle of Lanercost records the death in 1229 of "comes de Fif, Malcolmus", the succession of "nepos eiusdem…Malcolmus", adding that the latter married "filia Leulini senioris domini Walliæ".  The last source is the only one of the three which does not state that the new earl´s marriage was later than his succession.  Her birth date is estimated on her having given birth to her known son in [1244/46], which suggests that the couple married at least ten years after Malcolm became earl.  It is assumed that she was illegitimate.  If she had been her father´s legitimate daughter, the absence in the sources of any reference to her descent from John King of England would be surprising.  The second marriage of the widow of Malcolm Earl of Fife is confirmed by the documents under which "Elenæ comitissæ de Marre" accounted for payment of "xl s pro parte dotis suæ" in the accounts of lands formerly belonging to Duncan Earl of Fife 20 Nov 1293 and 16 Feb 1294.  However, it is not certain that this widow of Earl Malcolm was the same person as his wife who was the daughter of Prince Llywelyn.  The birth of Earl Malcolm´s son Colban is estimated to [1244/46].  However, Earl Malcolm´s widow had four known children by her second husband.  This would mean that she gave birth to children over an approximately thirty year span, which although not impossible would be unusual.  In addition, it seems unlikely that Earl Donald would have married, as his first marriage, a woman who would have been more than 35 years old.  m [firstly] [as his first wife,] MALCOLM Earl of Fife, son of DUNCAN Macduff of Fife & his wife Alice Corbet (-1266).  [m secondly (after 1266) DONALD Earl of Mar, son of WILLIAM Earl of Mar & his first wife Elizabeth Comyn of Buchan (-after 25 Jul 1297).]

Llywelyn the Great
(Welsh: Llywelyn Fawr, [ɬəˈwɛlɨn vaur]), full name Llywelyn ap Iorwerth, (c. 1172 – 11 April 1240) was a Prince of Gwynedd in north Wales and eventually de facto ruler over most of Wales. By a combination of war and diplomacy he dominated Wales for 40 years.

During Llywelyn's boyhood, Gwynedd was ruled by two of his uncles, who split the kingdom between them, following the death of Llywelyn's grandfather, Owain Gwynedd, in 1170. Llywelyn had a strong claim to be the legitimate ruler and began a campaign to win power at an early age. He was sole ruler of Gwynedd by 1200 and made a treaty with King John of England that year. Llywelyn's relations with John remained good for the next ten years. He married John's natural daughter Joan in 1205, and when John arrested Gwenwynwyn ab Owain of Powys in 1208, Llywelyn took the opportunity to annex southern Powys. In 1210, relations deteriorated, and John invaded Gwynedd in 1211. Llywelyn was forced to seek terms and to give up all lands east of the River Conwy, but was able to recover them the following year in alliance with the other Welsh princes. He allied himself with the barons who forced John to sign the Magna Carta in 1215. By 1216, he was the dominant power in Wales, holding a council at Aberdyfi that year to apportion lands to the other princes.

Following King John's death, Llywelyn concluded the Treaty of Worcester with his successor, Henry III, in 1218. During the next fifteen years, Llywelyn was frequently involved in fights with Marcher lords and sometimes with the king, but also made alliances with several major powers in the Marches. The Peace of Middle in 1234 marked the end of Llywelyn's military career, as the agreed truce of two years was extended year by year for the remainder of his reign. He maintained his position in Wales until his death in 1240 and was succeeded by his son Dafydd ap Llywelyn.

Llywelyn was born about 1173, the son of Iorwerth ap Owain and the grandson of Owain Gwynedd, who had been ruler of Gwynedd until his death in 1170. Llywelyn was a descendant of the senior line of Rhodri Mawr and therefore a member of the princely house of Gwynedd. He was probably born at Dolwyddelan though not in the present Dolwyddelan castle, which was built by Llywelyn himself. He may have been born in the old castle which occupied a rocky knoll on the valley floor. Little is known about his father, Iorwerth Drwyndwn, who died when Llywelyn was an infant. There is no record of Iorwerth having taken part in the power struggle between some of Owain Gwynedd's other sons following Owain's death, although he was the eldest surviving son. There is a tradition that he was disabled or disfigured in some way that excluded him from power.

By 1175, Gwynedd had been divided between two of Llywelyn's uncles. Dafydd ab Owain held the area east of the River Conwy and Rhodri ab Owain held the west. Dafydd and Rhodri were the sons of Owain by his second marriage to Cristin ferch Goronwy ab Owain. This marriage was not considered valid by the church as Cristin was Owain's first cousin, a degree of relationship which according to Canon law prohibited marriage. Giraldus Cambrensis refers to Iorwerth Drwyndwn as the only legitimate son of Owain Gwynedd. Following Iorwerth's death, Llywelyn was, at least in the eyes of the church, the legitimate claimant to the throne of Gwynedd.

Llywelyn's mother was Marared, occasionally anglicised to Margaret, daughter of Madog ap Maredudd, prince of Powys. There is evidence that, after her first husband's death, Marared married in the summer of 1197, Gwion, the nephew of Roger Powys of Whittington Castle with whom she had a son, David ap Gwion. Therefore, some maintain that Marared never married into the Corbet family of Caus Castle (near Westbury, Shropshire) and later, Moreton Corbet Castle. However, there is in existence a grant of land from Llywelyn ab Iorworth to the monastery of Wigmore, in which Llywelyn indicates his mother was a member of the house of Corbet, leaving the issue unresolved. ...

In his later years Llywelyn devoted much effort to ensuring that his only legitimate son Dafydd would follow him as ruler of Gwynedd and amended Welsh law as followed in Gwynedd. Llywelyn's amendment to Welsh law favoring legitimate children in a Church sanctioned marriage mirrored the earlier efforts of the Lord Rhys, Prince of Deheubarth in designating Gruffydd ap Rhys II as his heir over those of his illegitimate eldest son Maelgwn ap Rhys. In both cases, by favoring legitimate children born in a Church sanctioned marriage would facilitate better relations between their sons and the wider Anglo-Norman polity and Catholic Church by removing any "stigma" of illegitimacy. Dafydd's older but illegitimate brother, Gruffydd, was therefore excluded as the primary heir of Llywelyn, though would be given lands to rule. This was a departure from Welsh custom, which held that the eldest son was his father's heir regardless of his parent's marital status. ...

In 1226 Llywelyn persuaded the Pope to declare his wife Joan, Dafydd's mother, to be a legitimate daughter of King John,
again in order to strengthen Dafydd's position, and in 1229 the English crown accepted Dafydd's homage for the lands he would inherit from his father. In 1238 Llywelyn held a council at Strata Florida Abbey where the other Welsh princes swore fealty to Dafydd. Llywelyn's original intention had been that they should do homage to Dafydd, but the king wrote to the other rulers forbidding them to do homage. Additionally, Prince Llywelyn arranged for his son Dafydd to marry Isabella de Braose, eldest daughter of William de Braose. As William de Braose had no male heir, Llywelyn strategized that the vast de Braose holdings in south Wales would pass to the heir of Dafydd with Isabella. ...

Joan died in 1237 and Llywelyn appears to have suffered a paralytic stroke the same year.
From this time on, his heir Dafydd took an increasing part in the rule of the principality. Dafydd deprived his half-brother Gruffydd of the lands given him by Llywelyn, and later seized him and his eldest son Owain and held them in Criccieth Castle. In 1240 the chronicler of Brut y Tywysogion records: "the lord Llywelyn ap Iorwerth son of Owain Gwynedd, Prince of Wales, a second Achilles, died having taken on the habit of religion at Aberconwy, and was buried honourably."

Llywelyn died at the Cistercian abbey of Aberconwy, which he had founded, and was buried there. This abbey was later moved to Maenan, becoming the Maenan Abbey, near Llanrwst, and Llywelyn's stone coffin can now be seen in St Grwst's Church, Llanrwst. ...

Among the poets who lamented his passing was Einion Wan:

True lord of the land – how strange that today
He rules not o'er Gwynedd;
Lord of nought but the piled up stones of his tomb,
Of the seven-foot grave in which he lies.

Dafydd succeeded Llywelyn as prince of Gwynedd, but King Henry was not prepared to allow him to inherit his father's position in the remainder of Wales. Dafydd was forced to agree to a treaty greatly restricting his power and was also obliged to hand his half-brother Gruffydd over to the king, who now had the option of using him against Dafydd. Gruffydd was killed attempting to escape from the Tower of London in 1244. This left the field clear for Dafydd, but Dafydd himself died without issue in 1246 and was eventually succeeded by his nephew, Gruffydd's son, Llywelyn ap Gruffudd.


Llywelyn married Joan, natural daughter of King John of England, in 1205.
Llywelyn and Joan had three identified children in the records but in all probability had more as Llywelyn children were fully recognised during his marriage to Joan whilst his father in law King John was alive. The identity of the mother of some of Llywelyn's children before this union is uncertain, but the following are recorded in contemporary or near-contemporary records.

Dafydd ap Llywelyn (c. 1212–1246), son by Joan, wife of Llywelyn.
Elen (Helen) ferch Llywelyn (c. 1206-1253), daughter by Joan. M. John Earl of Huntington m. 2nd Robert de Quincy 3rd Donald Malcolm Mar Earl of Mar.
Susanna ferch Llywelyn, died after November 1228, daughter by Joan. Henry III King of England granted the upbringing of "L. princeps Norwallie et Johanna uxor sua et…soror nostra Susannam filiam suam" to "Nicholao de Verdun et Clementie uxori sue" by order dated 24 Nov 1228[273]. Her birth date is estimated on the assumption that Susanna was under marriageable age, but older than an infant, at the time.
Gruffydd ap Llywelyn (c. 1196–1244), a son by Tangwystl Goch (d. c. 1198).
Gwladus Ddu (c. 1206–1251), probable daughter by Joan.
Angharad ferch Llywelyn (c. 1212-1256), probable daughter of Joan; married Maelgwn Fychan.
Marared ferch Llywelyn (died after 1268), married John de Braose and secondly (about 1232) Walter III de Clifford. Marared had issue by both husbands.
Elen the Younger ferch Llywelyn (before 1230-after 16 Feb 1295) who married firstly Máel Coluim II, Earl of Fife, son of Duncan Macduff of Fife & his wife Alice Corbet. She married secondly (after 1266) Domhnall I, Earl of Mar, son of William, Earl of Mar & his first wife Elizabeth Comyn of Buchan. Elen and Domhall's daughter, Isabella of Mar, married Robert, the Bruce, King of Scots. Isabella had one child by the King of Scots, Marjorie Bruce, who was the mother of the first Stewart monarch, Robert II of Scotland.
Tegwared y Baiswen ap Llywelyn (c. 1215), a son by a woman named as Crysten in some sources, a possible twin of Angharad

Little is known of Llywelyn's mistress, Tangwystl Goch, except that she was the daughter of Llywarch "Goch" of Rhos. Gruffydd ap Llywelyn (c. 1196–1244) was Llywelyn's eldest son and known to be the son of Tangwystl. He married Senena, daughter of Caradoc ap Thomas of Anglesey. Their sons included Llywelyn ap Gruffudd, who for a period occupied a position in Wales comparable to that of his grandfather, and Dafydd ap Gruffydd who ruled Gwynedd briefly after his brother's death.
