a son of Rhys Fychan , last lord of Geneu'r Glyn in north Cardiganshire , and a descendant of Maelgwn (q.v.) ap Rhys ap Gruffydd (q.v.) .

The campaign in west Wales comprised a hard, but unsuccessful, siege of Llanbadarn ( Aberystwyth ) and heavy raids into Carmarthen and Pembroke . Maelgwn was killed by the men of the earl of Gloucester while fighting near Carmarthen . His brothers, Rhys and Gruffydd , were held in the king's prison at Norwich as late as 1308 .
