Guaire Aidne mac Colmáin

A member of the Ui Fiachrach Aidhne and son of king Colmán mac Cobthaig (died 622).

In 629 was fought the Battle of Carn Feradaig (Carhernarry, County Limerick), where he suffered a defeat at the hands of the Munster king Faílbe Flann mac Áedo Duib (died 639).

Diarmait won the support of the monastery of Clonmacnoise and refused the request of Cumméne Fota (died 662), the abbot of Clonfert, for a truce; who had been sent by Guaire to ask for one.

However, Guaire was able to turn his defeat into a moral victory when upon submitting to Diarmait he outdid the high-king with his generosity to the poor.

Byrne believes this is not probable however; based on Cúán mac Amalgado's death date in the annals and on the improbability of the Uí Liathain being involved in a conflict far from their territory in South Munster.

[7] Anecdotes are told about his relations with such saints as Cumméne Fota of Clonfert, Caimmín of Inis Celtra, and Colmán mac Duach of Kilmacduagh.

Guaire is the ancestor of the families of Ó Cléirigh, O'Shaughnessy, Colton, Mac Kilkelly, Hynes, O'Dowd, and others.
