Origin
The surname Dufresne has its origins in France, tracing back to the medieval period. It is derived from the Old French words "du" meaning "of" and "fresne" meaning "ash tree." This suggests that the name may have originated as a locational surname, referring to someone who lived near an ash tree or in an ash-tree grove.
One of the earliest recorded references to the name Dufresne can be found in the Domesday Book, a comprehensive survey of landowners in England commissioned by William the Conqueror in 1086. The entry "Radulfus de Fraxino" appears in this historical document, which is believed to be an early variation of the surname Dufresne.
During the 13th century, the name Dufresne began to appear in various records throughout France. In 1245, a certain Guillaume Dufresne was mentioned in the court records of Chartres, a city located in the northern region of France. Around the same time, historical documents from the Normandy region also referenced individuals with the surname Dufresne.
Notable individuals with the surname Dufresne include Jacques Dufresne (1615-1688), a French painter and engraver from Paris who was renowned for his religious works. Jean Dufresne (1641-1724) was a French composer and organist who served at the court of Louis XIV. Marie-Jeanne Dufresne (1702-1775), also known as Madame Favart, was a celebrated French actress and playwright in the 18th century.
In the 19th century, Adolphe Dufresne (1828-1900) was a prominent French journalist and writer who founded the newspaper Le Petit Moniteur. Another notable figure was Charles Dufresne (1853-1936), a French botanist who made significant contributions to the study of plant classification and taxonomy.
The surname Dufresne has also been found in various spellings throughout history, including Dufrayne, Dufraine, and Dufraigne. These variations likely emerged due to regional dialects and the evolution of language over time. Additionally, the name has been associated with certain place names, such as Fresne in Normandy and Fresnay in the Loire Valley region of France.
Demographics
Among Census respondents with the surname Dufresne, the largest self-reported group is White at 85.9%. The next largest groups are Black (6.0%) and Two or More Races (3.7%).
The bar chart below shows how Dufresne 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 Dufresne 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 Dufresne (2000, 2010, 2020).
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.
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.
