Rhys ap Gruffydd
Following Henry I's death in 1135, anarchy followed due to conflict between rival claimants. Gruffydd took the opportunity to reconstruct Deheubarth. Raising an army, Gruffydd conquered much of former Deheubarth including Cemais by 1136. Robert fitz Martin was expelled from the lands. His son, William Fitz Martin, received Kemes as a dowry when he married Angharad, a daughter of Rhys ap Gruffydd.
