Toirdhealbhach Óg Donn Ó Conchobair

Cathal mac Ruaidri Ó Conchobair, died 14 May 1461.

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.
