Married/ Related to:  Madog ap Maredudd of Powys, Prince of Powys 1)Died 1160 Notes: Madog was the son of Maredudd ap Bleddyn and grandson of Bleddyn ap Cynfyn. He followed his father on the throne of Powys in 1132. He is recorded as taking part in the Battle of Lincoln in 1141 in support of the Earl of Chester, along with Owain Gwynedd's brother Cadwaladr ap Gruffydd and a large army of Welshmen. In 1149 he is recorded giving the commote of Cyfeiliog to his nephews Owain Cyfeiliog and Meurig. The same year Madog was able to rebuild Oswestry Castle, a fortress of William Fitzalan. It would seem likely that he had gained both the fortresses of Oswestry and Whittington in 1146. Child: | |||
