History

The Ó Conor ''Don'' is the head of a lineage which provided about one hundred Kings of Connacht, thirty Chiefs of the Name and two High Kings of Ireland, Tairrdelbach Ua Conchobair (1088–1156), and his son Ruaidrí Ua Conchobair (c. 1115–1198), the last High King. During the late 14th century, the Ó Conor dynasty was grouped into two main divisions, one led by Toirdhealbhach Óg Donn Ó Conchobair, the other by Felim MacAedh Ó Conchobair. From these descended the families of Ó Conchubhair Donn anglicized as O'Conor Don and Ó Conchubhair Ruadh anglicized as O'Conor Roe (now extinct). The O'Conor family like all Gaelic Nobility followed Brehon law system up until the 16th century. Therefore, they did not follow
