Rosier
A surname most often linked to the French word for a rosebush, and sometimes to a place-name or continental immigrant family.
The #8,288 most common surname in the United States (2010 Census) — about 1 in every 77,244 Americans shares it.
Etymology
Rosier is usually explained from French rosier, meaning a rosebush or rose tree. In surname use, it could have begun as a topographic name for someone living near roses or a rose garden, or as a habitational name from a place called Rosier or something similar. Older English writers also connected it with Middle English roser, but the French origin is the stronger and more common explanation.
History
The surname appears in English records from the medieval and early modern periods, and it may have been reinforced by arrivals from France and the Low Countries. Nineteenth-century surname writers often treated Rosier alongside continental names such as Rosher and Roscher, which fits a cross-Channel history. In England it remained relatively uncommon, while in French-speaking areas it is more naturally understood as a name derived from the rosebush.
