Colman mac Duagh

Saint Colman mac Duagh (c. 560 – 29 October 632) was born at Corker, Kiltartan, County Galway, Ireland, the son of the Irish chieftain Duac. He initially lived as a recluse, living in prayer and prolonged fastings, first on Inismore, then in a cave at the Burren in County Clare. With his relative, King Guaire Aidne mac Colmáin (d. 663) of Connacht he founded the monastery of Kilmacduagh, ("the church of the son of Duac"), and governed it as abbot-bishop.
