My ancestors were the prince of Wales, Rhys ap Tewdwr and The Lord Rhys . They were princes of South Wales. Also David Price was from Brecknockshire, Wales and married Joan Awbrey who was from Brecknockshire Castle in Wales. I believe Gwenydd is the area they are connected with. (David and Joan came to America in 1693 to Philadelphia.)
I understand that after Rhys ap Tewdwr was killed by the Normans the rest of the family may have gone back to Ireland.
