RHODRI ap GRUFFYDD (d. c. 1315 ), prince of Gwynedd ;

third son of Gruffydd ap Llywelyn (q.v.) and Senana , and brother of Owain Goch (q.v.) , Llywelyn ap Gruffydd (q.v.) , and Dafydd ap Gruffydd (q.v.) . His first appearance is as a child hostage in the hands of Henry III in 1241 . Probably released in 1248 , he returned to Wales when Owain and Llywelyn went surety for his loyalty to the king. He later became a victim of Llywelyn 's drive against the custom of partible succession; but after some years in prison he agreed, in 1272 , to quitclaim his rights in Gwynedd in return for a grant from Llywelyn of 1,000 marks. This agreement was not immediately implemented, and Rhodri escaped to England . On two subsequent occasions Edward I intervened to enforce the contract; only 50 marks had been paid by the end of 1278 , but at least another 100 marks had been handed over at Aberconwy by Nov. 1280 . In 1292 he received an annual pension of £40 from the king. Meanwhile he had m., in 1281 , Beatrice , daughter and heiress of David de Malpas , and appears henceforth as a landowner of some standing in Cheshire as well as the lord of a manor in Surrey . After the death of Beatrice , in 1290 , he took as his second wife one named Catherine , who survived him. There was one son of this marriage — Thomas ap Rhodri (q.v.) , father of Owain ap Thomas ap Rhodri (or Owain Lawgoch ) (q.v.) .
