MORGAN , rebel of 1294 .

He was the leader of the Glamorgan insurgents during the rising of Madog ap Llywelyn (q.v.) in 1294-5 . Owing to personal grievances against the De Clares , he claimed to be at war only against the lords of Glamorgan . He may, therefore, have been Morgan ap Maredudd , a direct descendant of Rhydderch ap Iestyn (q.v.) [No article found] ; his father, Maredudd , the last native lord of Caerleon , had been deprived twenty years earlier by Gilbert de Clare . He has also been described in one contemporary chronicle as Rhys ap Morgan , which suggests some confusion with Rhys , the younger son of Morgan Fychan ap Morgan Gam (q.v.) . Morgan submitted to the king in July 1295 , and obtained the royal clemency. His daughter, Angharad , was an ancestress of the Morgan of Tredegar family. [See Morgan ap Hywel for Maredudd ].
