Mahoney Surname History
Early Origins of Mahoney History
Mahoney was first found in County Cork (Irish: Corcaigh) the ancient Kingdom of Deis Muin (Desmond), located on the southwest coast of Ireland in the province of Munster, where they held a family seat from ancient times.
“The O’Mahonys were anciently located in Cork and Kerry, where they were powerful Chiefs and sometimes styled Princes. They had several castles along the sea-coast. In County Cork an O’Mahony was Lord of Ivaugh, in the Barony of West Carbery, and an O’Mahony was Chief in Kinalea Barony. In County Kerry there was a Chief of the name in the Barony of Iveragh, and there were O’Mahonys in the Barony of Clanmaurice. The majority of persons of the name of Mahony or O’Mahony are still found in these two counties.”
The Book of Munster clearly states: “The O’Mahony family were ‘undisputed kings of Raithlean, and had a right to be kings of Cashel whenever that kingdom happened to be vacant; and from whom the Kings of Cashel had no right to demand anything except a bowing of the head.’ “
The many Irish surnames in use today have long rich histories behind them. The name Mahoney originally appeared in Gaelic as O Mathghamhna, which is derived from the word mathghamhan, which means bear. The modern Gaelic spelling is O Mahúna.
“Hugh Gharbh (or Hugh the Terrible), a younger brother of Laeghaire who is No. 93 on the ‘O’Donaghue’ (of Lough Lein) pedigree, was the ancestor of O’Mathamhna; anglicized O’Mahony and Mahony.”
