Grainger (surname)

Grainger is a surname of English origin. It is a variant of the surname  which is an occupational name for a farm bailiff. The farm bailiff oversaw the collection of rent and taxes from the barns and storehouses of the lord of the manor. This officer's Anglo-Norman title was grainger, and Old French grangier, which are both derived from the Late Latin granicarius (a derivative of granica, meaning "granary").
