Philip de Barry (fl. 1183), was a Cambro-Norman warrior from Manorbier in Pembrokeshire who participated in the colonisation of Kingdom of Desmond following the Norman invasion of Ireland. He was the founder of the Barry or De Barry family in County Cork, and common ancestor of the barons Barry and earls of Barrymore. Philip was born circa 1137/44 and was described by his brother Gerald as "a wise and honourable man" (vir probus ac prudens). He died while his brother Gerald was at Rome in 1199-1200 and was entombed in the church of Manorbier. Ancestry Nesta Philip's role in the invasion and colonisation of Ireland, and his position in the medieval Welsh-Irish Norman society, was largely due to his membership of the extended family of descendants of Princess Nest or Nesta of Deheubarth. Nest had three sons and a daughter by her first husband Gerald de Windsor: the daughter, Angharad, married William de Barry. William de Barry Philip was the son of William Fitz Odo de Barry was the son of Odo or Otho, a Norman knight who assisted in the Norman Conquest of England and Wales during the 11th century. William rebuilt Manorbier Castle in stone and the family retained the lordship of Manorbier until the 15th century. Philip's mother was Angharad, daughter of Gerald and Nest. Philip succeeded his father at Manorbier. His uncle (his mother Angharad's half brother) was Robert Fitz-Stephen whose cousins were the founders of the great FitzGerald and Carew families in Ireland. Philip's full brothers were Robert and Gerald. Robert de Barry accompanied his half-uncle Robert Fitz-Stephen in the Norman invasion of Ireland and took part in the Siege of Wexford. While some sources say that he was killed at the battle of Lismore in 1185, this is probably not true (see note below). Gerald of Wales, alias Giraldus Cambrensis, was a clergyman and historian. He also had a half-brother - Walter. Lands in Ireland Philip de Barry came to Ireland at the end of February 1183, accompanied by his brother Gerald and their followers, to take possession of his lands and to assist his half-uncle Robert Fitz-Stephen, and his first cousin Raymond FitzGerald (also known as Raymond Le Gros), in their efforts to recover lands in the modern county of Cork. These cantrefs or baronies had been expropriated by another (half) first cousin, Ralph Fitz-Stephen (or Radulph). Ralph was the grandson of Nesta
