Born in Co. Donegal, Ireland, about 550. He was appointed Abbot of Fahan by St. Columba. The monastery was anciently known as Othan Mor, but after the death of our saint was called Fahan Mura. He was highly esteemed by Hugh, Head King of Ireland, whose obit is chronicled in 607. Numerous legends are told of Mura; he wrote many works, including chronicles and a rhymed life of St. Columba, which is quoted in the Martyrology of Donegal. He is regarded as the special patron saint of the O'Neill clan, being sixth in descent from the founder, whose name survives in Innishowen (Inis Eoghan). His death occurred about 645, and his feast is observed on 12 March. Among his relics still preserved are his crozier (Bachall Mura), now in the National Museum, Dublin, and his bell-shrine, now in the Wallace Collection, London. In the ruined church of St. Mura at Fahan is a beautiful Irish cross, and not far off is St. Mura's Well.
