Meaning & Origin
A patrilineal surname transferred from the given name.
Fitzpatrick is a boy's baby name, an Irish surname-turned-first-name of Norman French and Irish origin, meaning 'son of Patrick' — with Fitz- from Norman French fils ('son') and Patrick from Latin Patricius meaning 'nobleman.' The Fitzpatrick family is one of Ireland's most ancient Gaelic dynasties.
Fitzpatrick carries the dual heritage of Norman conquest and Irish Gaelic tradition — one of those rare names that tells the entire history of Ireland's complex medieval past in a single surname transferred boldly into the first-name position.
