Cosgrove

The Cosgrove surname is of Irish origin, derived from the Gaelic *Ó Coscraigh*, meaning "descendant of Coscrach," a personal name meaning "victorious" or "triumphant." The family traces its roots to the ancient Kingdom of Uí Maine, which encompassed parts of present-day Counties Galway and Roscommon. For centuries, the Cosgroves served as respected landholders, clergy, and community leaders throughout western Ireland. The surname later spread across Ireland and, through emigration, to North America, Britain, Australia, and New Zealand. Today, the Cosgrove name represents a proud Irish heritage rooted in perseverance, leadership, and a lasting connection to the historic Gaelic families of Connacht.
