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
primogeniture. The Kings, or Chiefs of the O'Conor family would be elected by a close
kinship group. This did frequently result in bitter feuds and lead to civil wars within the Kingdom, therefore at times dramatically weakening the family's power in
Connacht and in
Ireland.
