PHILIP DE ORREBY, presumably elder son by 1st wife, born circa 1190, was witness with his father to Earl Ranulph's charter to William de Cauntelo, as Philip de Orreby the younger. He married Leucha, daughter of Roger DE MOHAUT (son of Robert de Mohaut by Leucha his wife), and died v.p., leaving a daughter Agnes, who in or before 1227 was her mother's heir.
