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 form of a Clan and is a group of people whose ancestors all bore the same surname and inhabited the same locality.
