Niall Mac Lochlainn

Niall Mac Lochlainn (died 1176) was a king of Cenél nEógain and Cenél Conaill. He was a member of the Meic Lochlainn, and a son of Muirchertach Mac Lochlainn, King of Cenél nEógain (died 1166). Ruaidrí Ua Conchobair, King of Connacht (died 1198) divided Tír nEógain between Niall and Áed Méith Ua Néill (died 1230). Muirchertach's granddaughter, Findguala, who married Guðrøðr Óláfsson, King of Dublin and the Isles (died 1187), appears to have been a daughter of Niall.
