Origin
Meaning and origin of Mailloux
The surname Mailloux is of French origin, tracing its roots back to the regions of Brittany and Normandy in northwestern France. It emerged during the medieval period, likely between the 11th and 13th centuries.
The name is believed to be derived from the Old French word "maille," meaning a small ring or mesh of a net or chainmail. This connection suggests that the name may have been an occupational surname, originally referring to someone who crafted or worked with chainmail armor or fishing nets.
In its earliest recorded forms, the name appeared with various spellings, such as Malloue, Maillou, and Maillouw, reflecting the linguistic variations of the time. These variations can be found in historical documents and records from the region, although specific mentions in notable manuscripts are scarce.
One of the earliest documented individuals with this surname was Jean Mailloux, born around 1585 in the village of Baye, near the town of Sées in Normandy. He later emigrated to New France (present-day Quebec, Canada) in the early 17th century, where the name took root and flourished among French colonists.
Another notable figure was Pierre Mailloux, born in 1632 in the parish of Notre-Dame de Cogne, near the city of La Rochelle in western France. He was among the first settlers in the Acadian region of present-day Nova Scotia, Canada, where he and his descendants played a significant role in the early development of the Acadian community.
In the 17th and 18th centuries, the Mailloux surname was particularly prevalent in the regions of Normandy, Brittany, and Poitou in France, as well as in the French colonies of Canada and the Caribbean islands.
One prominent individual was François Mailloux, born in 1725 in the town of Bayeux, Normandy. He later became a renowned clockmaker and inventor, known for his innovative timepiece designs and contributions to the field of horology.
Another figure of note was Marie-Anne Mailloux, born in 1748 in the town of Châteauguay, Quebec. She was a respected midwife and herbalist, renowned for her expertise in traditional medicine and her dedicated service to the local community.
The Mailloux surname has also been associated with several place names in France, such as the village of Mailloux in the department of Charente-Maritime, and the hamlet of Maillouxville in the department of Eure-et-Loir, both reflecting the historical presence and influence of families bearing this name in those regions.

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 Mailloux surname at the time of the 2020 Census, not any inherent property of the name itself.

Is this page using the latest Census data?
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 Mailloux (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.
