Hugh Boy Ó Néill

Hugh Boy Ó Néill, called the Fair (died 1283), son of Domhnall Óg, was the last king of Ailech and eponym of the Clandeboye O'Neills. After Brian Chatha an Dúna fell in 1260 he took the kingship, expelling his brother Niall Cúlanch.

He married Eleanor, cousin of Earl Walter de Burgh, whom he acknowledged as overlord in 1269. In 1281 he killed Donnell Óg O'Donnell, and in 1283 was himself killed by Brian MacMahon and Gilla Ísa O'Reilly.
