Origin
Meaning and origin of Dubon
The surname Dubon has its origins in France, dating back to the mid-16th century. It is believed to have derived from the Old French words "du" and "bon," which translate to "of the good." The name was likely given to someone who was considered a virtuous or honorable individual.
One of the earliest recorded instances of the Dubon surname can be found in the French census records from the late 1500s, where it appears as a variation of the spelling "Dubon." This suggests that the name may have been initially used as a descriptive nickname before becoming an established surname.
In the 17th century, the Dubon family is documented as residing in the Provence region of southeastern France. Some historical documents from this period mention a Jean Dubon, a prominent merchant who lived in Marseille between 1612 and 1678.
As the Dubon name spread throughout France, it also found its way into neighboring regions. In the 18th century, there are records of a family with the surname Dubon living in the Jura region of eastern France, near the Swiss border.
One notable figure bearing the Dubon surname was François Dubon, a French engineer and architect who lived from 1739 to 1821. He was known for his work on several notable buildings in Paris, including the Palais-Royal and the Théâtre de l'Odéon.
Another significant individual with the Dubon name was Marie-Louise Dubon, a French painter and engraver who lived from 1772 to 1848. She was recognized for her portraits and landscape paintings, many of which were exhibited at the Paris Salon during her lifetime.
In the 19th century, the Dubon surname began to appear in other parts of Europe, including Belgium and Switzerland. One notable figure from this period was Jules Dubon, a Belgian writer and journalist who lived from 1851 to 1923. He was known for his work as a literary critic and his advocacy for the Walloon language and culture.
As families with the Dubon surname continued to migrate and settle in different regions, the name underwent various spelling variations, such as Dubond, Dubonne, and Dubonnet. Some of these variations may have been influenced by local dialects or linguistic adaptations.

The bar chart below shows how Dubon 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 Dubon 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 Dubon (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.
