MAELGWN ab OWAIN GWYNEDD (d. after 1173),
son of Owain Gwynedd by Gwladus, daughter of Llywarch ap Trahaearn, uterine brother of Iorwerth Drwyndwn (q.v.), and uncle of Llywelyn ap Iorwerth. In the partition of his father's dominions he received Anglesey, but was driven out of the island in 1173 by his half-brother, Dafydd. He fled to Ireland, returned later in the year, and was made a prisoner. His subsequent fate is unknown.
