From Ó Mathghamhna, ‘bear’ — a West Cork sept of the Eóghanacht, whose castles still stand along the Bantry and Kinsale coastline.
Gaelic Origin · Root meaning ‘bear’
Mahony comes from mathghamhain, ‘bear’ — bears having vanished from Ireland long before the name was given, so it likely honoured the animal's remembered strength rather than a living encounter. The Ó Mathghamhna, part of the Eóghanacht dynasty, held territory across West Cork's Kinelmeky and Ivagha, from Bantry to Dunmanway.
A name for an animal Ireland no longer had, kept alive anyway — proof that a good name outlasts even the thing it describes.
Irish form: Ó Mathghamhna
