Grenier
A French surname originally meaning a granary, loft, or grain store, often linked to someone who kept or lived by such a place.
The #5,345 most common surname in the United States (2010 Census) — about 1 in every 47,434 Americans shares it.
Etymology
Grenier comes from French grenier, meaning a granary or loft for storing grain. The word goes back to Old French and ultimately to Latin granarium, from granum, “grain.” In surname use, it likely began as a name for someone who worked with grain storage or who lived near a granary; some older sources also treat it as a local or topographic name tied to such a building.
History
The surname is well established in France, especially in French-speaking regions, and was noted by 19th-century name scholars as a distinctly French form. Because granaries and grain storage were central to rural life, the word could easily develop into either an occupational or location-based surname. Variants and related forms appear in older records with spellings such as Granier, Guernier, and Crenier.

Fun fact
Older French sources sometimes glossed grenier broadly as any storage loft or upper room, not just the modern idea of an attic.
