Mahoney (or O'Mahoney or Gaelic Ó Mathghamhna), (pronunciation: MAHN-ee or ma-HOE-nee and occasionally MAH-huh-nee) is an Irish surname that originated in the early eleventh century. The forebear of the Mahoneys was Mathghamhan (or Mathuin or Mahon), the grandson of Brian Boru. Mathghamhan was killed at the Battle of Clontarf in 1014.
The Mahoneys flourished in southern Ireland. They were princes of an area in Cork along the River Bandon. They ruled as sovereigns over this territory until the English conquest of Ireland. The meaning of the name is "descendant of bear."
So began our little tribe. I and mine are blessed to reside in Middle Tennessee.
