The Mulvihill name makes perfect sense to those who understand it. It made no sense to the English invaders of Ireland, who bastardised the names of families and townslands in this country. Baile Mor (Big Town) was translated by the dumb Brits as Ballymore (I ask you?) The sad decendants of this race are still in charge of the local island (I ask you?) Mulvihill is the way the Brits pronounced Maoil Micil (the typewriter doesn't let me show you that the sounds change with the genitive case etc. Maol means bald and the reference is to the tonsuring of the head to show reverence and devotion to Archangel Michael (Micael). Micil is the genetive of Micael (in other words Maol is a noun (not the adjective "bald" and Micil is genitive "of Michael". So, Maol Micil means "Devotee of Michael". Before that there were lists of personal names, like the Old Testament, where X begat Y, begat Mulvihill etc.
