Overview
Rhys ap Tewdwr (c. 1040 – 1093) was a king of Deheubarth in Wales and member of the Dinefwr dynasty, a branch descended from Rhodri the Great. Following the Norman Conquest, he had to pay William the Conqueror to keep his kingdom, which lasted until the end of William's reign.
Family
Rhys ap Tewdwr was born in the area which is now Carmarthenshire. As a member of the House of Dinefwr, he claimed the throne of Deheubarth following the death of his second cousin Rhys ab Owain, who was beheaded after the battle of Gwdig (modern day Goodwick) against Caradog ap Gruffydd in 1078.
He was a grandson of Cadell ab Einion ab Owain ab Hywel Dda and a great-grandson of Einion ab Owain, thus a descendant of Hywel Dda, king of the Britons.
He married more than once. His first wife was Catrin (or Gwladus) verch Iestyn (b. 1041 in Powys). The name of his last wife was Gwladys ferch Rhiwallon, daughter of Rhiwallon ap Cynfyn of the Mathrafal Dynasty of Powys.
