Born to the Irish nobility. Educated in Bangor Abbey, Ireland. Spiritual student of Saint Comgall of Bangor. Legend says that one day as Moloc stood on a rock on the Irish shore, the rock broke away, sailed across the sea, and came ashore on the island of Lismore in Loch Linnhe. However he travelled there, Moloc and Saint Comgall worked as missionaries in Scotland, Moloc ranging far and wide to the Picts. Founded monasteries on the Isle of Lismore, and at Rosemarkie and Mortlach in the territory of the Picts; Saint Malachy claims that Moloc founded 100 monasteries in Scotland.
