B. c.1130, s. of Madog ap Maredudd and Susanna, da. of Gruffydd ap Cynan; acc. 1160; m. Angharad, da. of Owain Gwynedd; issue: Madog, Owain; d. 1191.
At the death of Madog, Powys was divided, with Gruffydd taking most of the northern part, including Maelor. His brother Owain Fychan took Mechain, and his brother Owain Brogyntyn took Edeyrnion. When Owain Fychan was murdered in 1187, Gruffydd took his estates. Gerald of Wales recorded that archbishop Baldwin tried to persuade him to separate from his wife, who was a first cousin. Praised as a liberal patron, his political conduct seems to have been circumspect.
