Origin
Meaning and origin of Aubuchon
The surname AUBUCHON has its origins in France, dating back to the early Middle Ages. It is believed to have derived from the Old French word "aubuisson," which means "hawthorn bush" or "bramble." This suggests that the name may have been initially given to someone who lived near or worked with hawthorn bushes or brambles.
The earliest recorded instances of the AUBUCHON surname can be traced back to the region of Normandy in northern France. During the 11th and 12th centuries, the name appears in various historical documents and records from this area, often spelled as "Aubusson" or "Aubuchon."
One notable historical reference to the AUBUCHON name is found in the Domesday Book, a comprehensive survey of land ownership and taxation commissioned by William the Conqueror in 1086. The name is recorded as "Albuciun," which is likely an early spelling variation of AUBUCHON.
In the 13th century, a prominent figure named Jacques AUBUCHON (c. 1220-1285) was a renowned nobleman and landowner in the region of Brittany, France. His descendant, Jean AUBUCHON (1325-1397), was a respected knight who fought alongside King Charles V during the Hundred Years' War.
During the 16th century, the AUBUCHON family expanded its influence, and several members achieved notable positions. Pierre AUBUCHON (1490-1562) was a respected lawyer and magistrate in Paris, while his son, François AUBUCHON (1525-1593), served as a trusted advisor to King Henry IV.
Another prominent figure with the AUBUCHON surname was Marie AUBUCHON (1635-1702), a pioneering settler in New France (present-day Canada). She and her husband, Pierre Boucher, were among the first colonists to establish a settlement in the region now known as Quebec.
Over the centuries, the AUBUCHON name has been associated with various places and regions, including the village of Aubuchon in the Normandy region of France, as well as several towns and villages in Quebec, Canada, where descendants of the early French settlers established new communities.

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 Aubuchon 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 Aubuchon (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.
