Despite its Norman appearance, "Fitz-" being Norman French for "son of", in the vast majority of cases Fitzpatrick is an anglicisation of the Irish Mac Giolla Phadraig, meaning "son of the servant of (St.) Patrick". Similarly to other surnames containing Giolla, it has also been anglicised as "Kilpatrick" and, more rarely, "Gilpatrick", principally in Ulster, where it is most common in counties Fermanagh and Monaghan. The original Giolla Padraig from whom the surname is taken was the tenth-century ruler of the ancient kingdom of Upper Ossory, including parts of the present counties of Laois and Kilkenny. The surname was anglicised to Fitzpatrick in the early sixteenth century when the chief of the family accepted the title of Lord Baron of Upper Ossory from Henry VIII. Partly due to this, they managed to retain possession of a large portion of their original lands right up to the nineteenth century. Although the surname is now common and widespread throughout Ireland, the largest concentration is still to be found in Co. Laois, part of their original homeland.
