The Irish and Scottish surname Finn is a reduced anglicized form of the Gaelic name Ó Finn meaning “descendant of Fionn,” a byname meaning “white or fair-haired.” There were three main O'Finn clans in Ireland. The first belonged to Co. Sligo where their chiefs held sway over the lands of Calry on the shore of Laigh Gill. The Co. Sligo place name, Coolavin (in Irish Cuil O'bhFinn) means "the refuge place of the O'Finns". A second sept held church lands and property in Kilcolgan, Co. Galway and the third sept belonged to the ancient territory of Oriel (Counties Armagh and Monaghan). They spelt their name MacFhinn or Maginn. The name has been recorded in Scotland since the 16th Century.
