Fitzgibbon Origin and Meaning

The name Fitzgibbon is a boy's name meaning "son of Gilbert, son of the shining pledge".

Fitzgibbon comes from the obsolete name Gibbon, a diminutive of Gib, which is a medieval short form of Gilbert. That makes Fitzgibbon a subtle way to honor an ancestral Gilbert — you could always call him by the more modern nickname Fitz.
