Biography
Art MacBaron O'Neill was part of the O'Neill dynasty of Ulster, the illegitimate son of Matthew O'Neill, 1st Baron Dungannon. He was the half-brother of Brian O'Neill, Cormac MacBaron O'Neill and Hugh O'Neill, Earl of Tyrone. Art MacBaron (his middle name a reference to the title of his father) ruled over Oneilland south of Lough Neagh. He could speak fluent English unlike many of his relations.
He fought alongside the Earl during Tyrone's Rebellion (1594-1603). Despite a series of defeats against the Irish Army that culminated in the burning of their capital at Dungannon and retreat into the woods, they were able to agree the Treaty of Mellifont which restored them to royal favour under the new King James I. Art and his brothers were pardoned for their past activities and had their lands restored to them. He died in 1618.
Family
O'Neill had nine sons, one of whom was Owen Roe O'Neill who served as a mercenary in the Spanish Army for many years before returning to Ireland during the Irish Confederate Wars. Six of his other sons died during Tyrone's Rebellion, and Brian O'Neill was hanged as an outlaw in 1607. The two remaining sons also served in the Spanish Army.
