Sir Neil O'Neill (Irish: Niall Ua Néill; January 1658 – 8 July 1690),[1] 2nd Baronet of Killeleagh, County Antrim, was an Irish Jacobite, soldier and the Lord of Clandeboye, a powerful clan of the ancient Northern Uí Néill.[2]
O'Neill's portrait from 1680 by John Michael Wright is historically significant because it is the only surviving contemporary presentation of the traditional costume of an Irish chieftain. At his feet is the armour of a Japanese samurai as a symbol of victory over the oppression of Catholics; next to him is an Irish wolfhound as a symbol of Ireland.
