Gallagher surname meaning

Gallagher is an Irish patronymic, an anglicized form of Ó Gallchobhair, meaning “descendant of Gallchobhar.” The personal name Gallchobhar is traditionally analyzed from elements associated with a foreigner or stranger and help, though medieval name glosses should not be treated as a literal modern translation. The surname is strongly associated with Donegal, especially the Cenél Conaill tradition, but unrelated families can share the same broad patronymic origin. Gallacher, Gallaher, and Gallaugher show regional spelling histories. Parent’s name is the high-confidence catalog type because Ó directly signals descent from a personal name.
