MORGAN FYCHAN (d. 1288 ), lord of the Welsh barony of Avan Wallia (or Nedd-Afan) in the honour of Glamorgan ,

son of Morgan Gam (q.v.) . Like his father he was a supporter of the North Wales princes . He may for a time have been deprived of Avan , for in 1282 he is described merely as lord of a half commote in Baglan . His son, LLEISION (d. 1328 ), the first of the family to adopt the surname ‘ de Avene ,’ was certainly lord of Avan , being succeeded there in turn by his son and grandson, John and Thomas de Avene . Sometime after 1350 , Avan passed into the hands of the chief-lord , probably as a result of an exchange of lands effected by Jane , daughter and heiress of Thomas , and wife of William Blount . The younger son of Morgan Fychan , Rhys , who succeeded to his father's lands in Baglan , was, however, the ancestor of several well-known Glamorganshire families including the Mackworth s and the Williams es of Aberpergwm (qq.v.) .
