St. Columba 521-597, Born probaly in Donegal Ireland of royal descent he studied at Moville under St. Finnian then in Leinster at the monastery of Clonard under another St. Finnian. He was ordained before he was twenty-five and spent the next fifteen years preaching and setting up foundations at Derry, Durrow, and Kells. Possibly because of a family feud which resulted in the death of 3000 and for which he considered himself partly responsible he left Ireland at 42 and landed on the island of Iona off the coast of Scotland. There he built the monastery which was to become world famous. With SS Canice and Comgall he spread the gospel to the Picts; he also developed a monastic rule which many followed until the introduction of St. Benedicts. He died on Iona and is also known as Colm, Colum and Columcille
