Brian Ó Néill
Brian Ó Néill (c. 1265–1295) was a king of Tír Eoghain and the son of Hugh Boy Ó Néill. In 1291, after his uncle Niall Cúlánach was killed by Donnell Ó Néill, Brian secured the kingship with Norman aid from the vassals of Earl Richard Óg de Burgh.
He ruled with Norman backing until 1295, when Donnell defeated and killed him at the battle of Creeve. His son Henry later became king and founded the lordship of Clandeboye.
