McGranahan Family History

The names Granahan, McGranahan and Granaghan are derived from the native Gaelic Mag Reannachain Sept that was located in County Donegal. The name is taken from a Gaelic word that translates as 'sharp-pointed'. It is in the Northern Counties that the majority of descendants bearing these names can still today be found.

A Sept is an ancient Clan-like collective describing a group of persons whose immediate ancestors bore a common surname and inhabited the same territory.
