Grainger
An occupational surname for someone who looked after a grange, granary, or farm estate.
The #8,337 most common surname in the United States (2010 Census) — about 1 in every 77,730 Americans shares it.
Etymology
Grainger is a spelling variant of Granger, a name for a person connected with a grange. In medieval English usage, a grange was a farm, outlying estate, or granary, so the surname likely meant a steward, farmer, or manager of such a place. The root ultimately goes back through Old French to Latin granum, meaning "grain."
History
Historical surname dictionaries regularly treat Grainger as a form of Granger, and records show both spellings in England by the late 14th century. The name is especially associated with England, though it later spread to Scotland, Ireland, and the English-speaking world more widely. In modern usage, Grainger and Granger are both established surnames, with Grainger often reflecting a regional spelling tradition rather than a separate origin.

Fun fact
