Rozier
A surname of mixed and uncertain origin, often treated as a French name and sometimes linked to a place-name or to a rose-related word-root.
The #7,575 most common surname in the United States (2010 Census) — about 1 in every 70,393 Americans shares it.
Etymology
Rozier is usually explained as a French surname, but the exact derivation is not fully settled from the excerpted evidence. It may be connected with a place-name or with a French word built on the root of "rose," suggesting either someone from a rose-associated locality or a descriptive name. Because the available historical citation is only an incidental mention rather than a full etymological entry, this remains a cautious, best-fit explanation rather than a firm proof.
History
The name is found in English-language records and appears in modern American usage, but its deeper history is most plausibly French. Like many surnames of French origin, it may have entered English-speaking countries through migration and later spread widely in the United States. The excerpt provided does not supply a specific early bearer or a definitive homeland region.

Fun fact
Because the surname can look like it contains the word "rose," it is often assumed to be floral in origin, but older surname forms can be misleading and may reflect place-names instead.
