Overview
Sir Turlough McHenry O'Neill (died 1608) is known for having been killed together with his father, Henry, fighting for the crown in O'Doherty's Rebellion and for being the father of Sir Phelim O'Neill, who started the Irish Rebellion of 1641.
Birth and origins
Turlough was a son of Henry Oge O'Neill and his wife Cortine (or Catherine) O'Neill. Turlogh's father was called "oge" (cf. Irish óg, young) to distinguish him from Turlough's grandfather who was also named Henry O'Neill. His father was the head of the O'Neills of Kinard, who were a cadet branch that parted from the O'Neill More when Turlough's great grandfather Shane O'Neill (died 1517), a younger son of Conn More O'Neill, King of Tir Eoghan, received Kinard as appanage.
His mother was a daughter of Hugh O'Neill, Earl of Tyrone. Both parents were thus part of the Gaelic O'Neill Dynasty of Ulster.
