O'Neill: Irish Surname History & Coat of Arms

Ó Néill · 'descendant of Niall' (champion)

O'Neill is an anglicised form of the Irish Ó Néill, 'descendant of Niall'. Woulfe (1923) calls the Ulster family 'one of the most illustrious in Ireland': chiefs of Tir Eoghain and Kings of Ulster, who took their name from Niall Glúndubh, King of Ireland, killed in 919. He also records distinct O'Neill families in Thomond, Leinster and the Deisi.
