 He was baptised in Temple-Douglas, in the County Donegal parish of Conwal (midway between Gartan and Letterkenny), by his teacher and foster-uncle Cruithnechán.It is not known for sure if his name at birth was Colmcille or if he adopted this name later in life; Adomnán (Eunan) of Iona thought it was his birth name but other Irish sources have claimed his name at birth was Crimthann (meaning 'fox').In the Irish language his name means 'dove', which is the same name as the Prophet Jonah (Jonah in Hebrew is also 'dove'), which Adomnán of Iona as well as other early Irish writers were aware of, although it is not clear if he was deliberately named after Jonah or not.
