GERAGHTY Family History
Recorded in at least seventeen spellings including (Mac)Garrity, (Mac)Geraghty, Gerty, and Gearty, this interesting surname is of Irish origin. It is a patronymic, with "mac" denoting the son of, and was originally found in the form "Mag Oireachtach". This translates as "the son of a member of the Assembly (of Ireland)". The surname arose in an unusual way; at first it was O'Roduibh, but then taking the name of one namebearer Oireachtach O'Roduibh, in the 12th Century (see below), subsequent members of the clan began using this personal name as their surname.
