Ó Conchobhair Sligigh

Ó Conchobhair Sligigh (anglicised O'Conor Sligo), Gaelic-Irish family and Chief of the Name.

The Ó Conchobhair Sligigh were a branch of the Ó Conchobhair Kings of Connacht.

They were descended from Brian Luighnech Ua Conchobhair (k.1181), a son of Irish High-King Toirdelbach Ua Conchobair and were Lords of Sligo into the 17th century. They were also referred to as Clann Andrias after a son of Brian Luighnech. The family first established themselves in the tuath of Cairbre Drom Cliabh and went on to become Lords of Lower Connacht (Íochtar Connacht), modern-day County Sligo, by taking advantage of Hiberno-Norman rivalry which led to the removal of Fitzgerald holdings in the area by De Burgh Lords of Connaught, and the collapse of their power in the Burke Civil War. In later centuries they attempted to hold off the O'Donnells of Tyrconnell, eventually having to acknowledge their overlordship before the collapse of the Gaelic order after the Nine Years' War.
