Robert FitzStephen (died 1183) was a 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 (). 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. Career In Wales Robert succeeded his father in his office (Custos Campe Abertivi). He first appears in history in 1157, when King Henry II of England invaded Gwynedd. While the main royal army faced the forces of Owain Gwynedd east of the River Conwy, a force including Robert and his half-brother Henry Fitzroy (the illegitimate son of Nest and King Henry I) attacked Anglesey by sea. However, this force was defeated in a battle in which Robert was seriously wounded and Henry killed. Robert was captured in November 1165 by Rhys ap Gruffydd (The Lord Rhys) who was the nephew of his mother Nest. The King of Leinster appealed to Rhys (in 1167) to release Robert for an expedition to Ireland. Rhys did not oblige at the time, but in response to a further appeal in 1168 released Robert from captivity. In Ireland In 1167, the King of Leinster, Diarmait Mac Murchada, was deprived of his kingdom by the High King of Ireland. To recover his kingdom, the exiled king fled to Wales and from there to England and Aquitaine in France, in order to gain the consent of King Henry II of England to recruit soldiers. On returning to Wales, Fitz-Stephen helped him to organise a mercenary army of Norman and Welsh soldiers, including Richard de Clare, 2nd Earl of Pembroke, alias Strongbow. On 1 May 1169, Robert led the vanguard of Diarmait Mac Murchada's Cambro-Norman auxiliaries to Ireland, thereby precipitating the Norman invasion of Ireland. The main invasion party landed near Bannow strand, County Wexford with a force of 30 knights, 60 men-at-arms and 300 archers. The next day, Maurice de Prendergast landed at the same bay with ten knights and 60 archers. This force merged with about 500 soldiers commanded by Diarmait . In return for capturing Wexford,
