Origin
Meaning and origin of Blouin
The surname Blouin is of French origin, tracing its roots back to the northwestern region of France known as Normandy. It emerged during the Middle Ages, likely in the 11th or 12th century. The name is believed to be derived from the Old French word "blouin," which meant "blond" or "fair-haired."
Surnames based on physical characteristics were common during this period, and Blouin likely referred to a person with distinctive blond hair. The name may have originated as a nickname or a descriptive identifier before becoming a hereditary surname passed down through generations.
One of the earliest recorded instances of the name Blouin can be found in the Cartulaire de Marmoutier, a cartulary (collection of charters and records) from the Marmoutier Abbey in Tours, France, dating back to the 12th century. This document mentions individuals with the surname Blouin, indicating their presence in the region during that time.
In the 13th century, the name Blouin appeared in various records from the Duchy of Normandy, including legal documents and property transactions. This suggests that the name had established itself as a distinct surname within the Norman society of that era.
Notable individuals bearing the Blouin surname throughout history include:
1. Jean Blouin (c. 1590-1657), a French colonist and one of the first settlers in New France (present-day Quebec, Canada).
2. Pierre Blouin (1647-1715), a French-Canadian colonist and landowner in the seigneury of Rivière-du-Sud, Quebec.
3. Jean-Baptiste Blouin (1784-1853), a French-Canadian farmer and politician who served as a member of the Legislative Assembly of Lower Canada.
4. Auguste Blouin (1834-1898), a French-Canadian journalist and editor who founded several newspapers in Quebec.
5. Pierre Blouin (1905-1975), a French-Canadian sculptor and artist known for his religious works and public monuments.
While the name Blouin has its origins in France, it has since spread to other parts of the world, particularly through French emigration and colonization. Today, it can be found in various regions with French cultural influence, including Canada, the United States, and parts of the Caribbean.

The bar chart below shows how Blouin bearers described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Blouin surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Blouin (2000, 2010, 2020).
Does the Census include every surname?
No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
