Cú Ceanain Ó Con Ceanainn
Irish king
Cú Ceanain Ó Con Ceanainn,(died 1224) was King of Uí Díarmata, Ireland.
Cú Ceanain was a contemporary, and subject of, Cathal Crobhdearg Ua Conchobair, King of Connacht, who may have been his foster brother. The succession is unclear for almost a century till Donnell Ó Con Ceanainn is recorded as king upon his death at the Second Battle of Athenry in 1316.
