Toirdhealbhach Óg Donn Ó Conchobair
Cathal mac Ruaidri Ó Conchobair was a King of Connacht and the son of Aedh mac Tairdelbach Ó Conchobair. Few single members of the Ó Conchobair dynasty were able to assume overall control of the three main clan septs after the 1380s. Toirdhealbhach was one of the very last of the kings, who were by now reduced to their ancestral lands in County Roscommon.
