son of Owain Gwynedd by Christina, and younger brother of Dafydd ab Owain Gwynedd. His share of Owain's dominion was in Anglesey and Arfon, from which he was expelled in 1190 by his nephews, Gruffydd and Maredudd, the sons of Cynan. In 1193 he temporarily reoccupied Anglesey with the aid of a Manx force, having previously contracted to marry a daughter of Reginald, king of Man. Whether he returned from exile and shared in his brother Dafydd's humiliation in 1194 is unknown, but in the following year he died, and was buried, it is said, at Holyhead. He had earlier married a daughter of the ‘lord’ Rhys. There was a son, Gruffydd, who left no heirs.
