Robert Fitz-Stephen was a 12th century Cambro-Norman soldier, one of the leaders of the Norman invasion of Ireland, for which he was granted extensive lands in Ireland. He was a son of the famous Nest, daughter of Rhys ap Tewdwr, the last king of Deheubarth (South Wales). His father was Nest`s second husband, Stephen, Constable of Cardigan (Welsh: Aberteifi). Following the death of her first husband, Gerald de Windsor, her sons had married her to Stephen, her husband`s constable for Cardigan. By Stephen, she had another son, possibly two; the eldest was Robert, and the younger may have been Hywel.
