Son of an Irish chieftain named Turdough. Intellectual and spiritual student of the monk Saint Molua. Despite family opposition, he became a monk. Missionary monk throughout Ireland, Scotland, and the Hebrides. First bishop of Killaloe, Ireland, consecrated by Pope John IV. Recited the entire Psalter daily. His preaching was so persuasive that his own father gave up power to become a monk.
