History of the Fitzgibbon name

The FitzGibbons are a branch of the great Geraldine dynasty, descending from Gibbon, a pet form of Gilbert, and their chief line held one of Ireland's three hereditary Geraldine knighthoods: the White Knight, An Ridire Fionn, alongside the Knight of Glin and the Knight of Kerry. Their country lay on the Limerick-Cork border around Mitchelstown and Kilmallock. Edmund FitzGibbon, the last White Knight, notoriously betrayed the Sugán Earl of Desmond to the Crown in 1601. A very different bearer, John FitzGibbon, Earl of Clare, was the most hated man in late-18th-century Ireland as the Lord Chancellor who drove through the Act of Union. The name remains a Limerick and Cork one, with a Gaelic form, Mac Giobúin, used throughout.
