MAREDUDD ab OWAIN ab EDWIN (d. 1072 ), king of Deheubarth .

He stood five generations from Hywel Dda and was second cousin in the senior line to Rhys ap Tewdwr . When Gruffudd ap Llywelyn fell in 1063 , the old dynasty was restored under his leadership. His reign coincides with the first impact of the Norman conquest on South Wales . After a brief and unequal struggle, he acquiesced in the conquest of the border lands of Gwent and was rewarded by grants of land in England . This was in 1070 . Two years later he was killed by a fellow prince fighting on the banks of the Rhymney . He left one son, Gruffudd , who lived in exile on his father's English manors until killed attempting to regain his patrimony from Rhys ap Tewdwr .
