Feudal Lord of Ystrad Tywi and Dynevor, younger son of Rhys ap Griffith, Prince of South Wales. 1
RHYS GRYG ('Rhys the Hoarse,' d. 1234), prince; he is also called 'Rhys Fychan,' and both names are give him in the panegyric addressed to him by 'Prydydd y Moch' (Llywarch ap Llywelyn), and printed in _Myv. Arch._, i, 292-4. He was the fourth son of the 'lord' Rhys ap Gruffydd (1132-97), by Gwenllian, daughter of Madog ap Maredudd of Powys. He was an unreliable man, who rebelled against his father, played off one of his brothers against another, and played off king John against Llywelyn ap Iorwerth. Physical bravery he certainly had, but no consistency can be discovered in his actions-other than self-seeking; for his career, see Lloyd, History of Wales (consult index). From 1215, he was tolerably loyal to Llyewlyn ap Iorwerth, who at the Aberdovey council of 1216 confirmed him in the possession of the greater part of Cantref Mawr and Cantref Bychan, and of the commotes of Cydweli and Carnwyllion. Under Llywelyn's banner, he joyfully stormed Norman castles in South Wales, but in one such onset (the attack on Carmarthen castle, in 1234), he was mortally wounded-he d. at Llandeilo-fawr, and was buried at S. Davids. 2
The Chronicle of the Princes of Wales records that "Rhys and Maredudd the sons of the lord Rhys subjected the castle of Dinevwr and the castle of Cantrev Bychan" in 1195.
The Chronicle of the Princes of Wales records that "Rhys the Hoarse died at Llandeilo the Great and was buried in Menevia near the grave of his father" in 1233. 3
Rhys married Ellyw FERCH THOMAS, daughter of Sir Thomas AP GWGON and Unknown. (Ellyw FERCH THOMAS was born about 1154 in Llan-Gors, Talgarth, Breconshire, Wales.
Rhys also married Joan DE CLARE, widow of William DE BRIOUSE, daughter of Richard DE CLARE Earl of Hertford and Amice DE GLOUCESTER, before 1197. (Joan DE CLARE was born about 1179 in Tunbridge Castle, Kent, England.)
