Life He was the son of Maredudd ap Gruffudd (c.1234-c.1275) the last Welsh lord of Caerleon of Machen, and Maud, daughter of Cadwallon.

During 1283, he supported the rebellion of Dafydd ap Gruffydd, prince of Wales. He was the leader of the Glamorgan insurgents during the rising of Madog ap Llywelyn in 1294-5; under his leadership, the Welsh captured castles at Kenfig, Llangibby, and Morlais. Morgan submitted to king Edward I and in 1297, he became an esquire of Edward's household and his agent in south Wales. Family His daughter, Angharad, married Llewelyn ap Ifor, Lord of St. Clere.
