Origin
Meaning and origin of Langlois
The surname Langlois originated in France and dates back to the early Middle Ages. It is derived from the Old French "l'Anglois," meaning "the Englishman." This suggests that the name was originally given as a nickname to someone who had connections to England, or who possibly spoke English.
One of the earliest recorded mentions of the Langlois name can be found in the Domesday Book of 1086, which was a survey of landowners commissioned by William the Conqueror after the Norman conquest of England. This suggests that the name may have been brought to England by Norman settlers during this time period.
The name Langlois can also be traced back to various regions of France, including Normandy, Brittany, and the Loire Valley. In these areas, the name may have been associated with specific towns or villages, such as Langlois-sur-Mer or Langlois-en-Beauce.
Among the notable individuals with the surname Langlois throughout history are:
1. Nicolas Langlois (1640-1703), a French Catholic priest and historian who wrote extensively about the history of Normandy.
2. Sébastien Langlois (1701-1776), a French engraver and printmaker known for his portraits and religious works.
3. Eustache Hyacinthe Langlois (1777-1837), a French painter and lithographer who specialized in landscapes and genre scenes.
4. Victor Langlois (1829-1868), a French poet and writer who was part of the Parnassian literary movement.

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 Langlois 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 Langlois (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.
