Cadfan ap Cadwaladr

Cadfan ap Cadwaladr, Lord of Ceredigion (c. 1140 - c. 1215) was the elder son of Cadwaladr ap Gruffydd, the brother of Owain Gwynedd, King of Gwynedd and overlord of all Wales. His mother was his father's first wife, Gwerfel ferch Gwrgan. He was probably born in Ceredigion, where his father held extensive estates. His father was banished in 1144. He was made Lord of Ceredigion in 1149, but he was soon expelled by Hywel ab Owain Gwynedd, his cousin and a son of Owain Gwynedd, in 1150. He probably spent the rest of his life in exile in England. He married Gwenllian, a daughter of Owain Cyfeiliog. He is known to have had only one daughter: Tangwystl ferch Cadfan (born c. 1212).
