 Clan MacKinnon may also have some claim to being spiritual descendants of St Columba as after he founded his monastery on Isle Iona, the MacKinnons were the abbots of the Church for centuries.This would also account for the fact that Clan MacKinnon is amongst the ancient clans of Scotland.The cathedral of the Catholic Diocese of Argyll and the Isles is placed under the patronage of Saint Columba, as are numerous Catholic schools and parishes throughout the nation.
