Colmán mac Cobthaig
Colmán mac Cobthaig was a king of Connacht from the Ui Fiachrach. He was the first king of Connacht from the Ui Fiachrach Aidhne branch. This branch was descended from Eochu, the brother of Ailill Molt. According to the Book of Ballymote he was the grandson of Goibnenn mac Conaill, the first Aidne king mentioned in the annals, but Rawlinson Genealogies name his grandfather as Gabrán.
He succeeded as king sometime after 601. Both the Book of Leinster and the Laud Synchronisms consider him the successor of Uatu mac Áedo and give him a reign of 25 and 21 years respectively.
The annals report that in 622 was fought the Battle of Cennbag where he was slain. He was defeated by his successor Rogallach mac Uatach of the Uí Briúin branch.
His sons included: Laidgnen/Loingsech mac Colmáin and Guaire Aidne mac Colmáin future kings of Connacht.
