Origin
Meaning and origin of Dufraine
The surname Dufraine has its origins in France, where it first emerged in the early Middle Ages, around the 11th century. The name is believed to be derived from the Old French words "duf" or "duif," meaning "dovecote" or "pigeon house," and "reine," meaning "queen." This suggests that the earliest bearers of this name may have been associated with a royal dovecote or pigeon house.
One of the earliest recorded instances of the Dufraine surname can be found in the Livre des Bourgeois de Rouen, a register of the citizens of Rouen, Normandy, dating back to the 14th century. This document mentions a certain "Jehan Dufraine," indicating the presence of this surname in the region at that time.
In the 15th century, the Dufraine name appeared in various historical records across northern France, particularly in the regions of Normandy and Picardy. During this period, the name was also spelled in various ways, including "Dufresne," "Dufrayne," and "Dufraisne," reflecting the fluidity of spelling conventions in those times.
One notable figure bearing the Dufraine surname was Jacques Dufraine, a French writer and historian who lived in the 16th century. Born in Rouen in 1518, he is known for his work "Histoire de Normandie," which chronicled the history of the Normandy region.
Another individual of note was Pierre Dufraine, a French architect who lived in the 17th century. Born in Amiens in 1622, he gained recognition for his work on several religious buildings, including the Church of Saint-Germain-des-Prés in Paris.
In the 18th century, the Dufraine name continued to appear in various records across France. One notable figure from this period was Nicolas Dufraine, a French botanist born in Dijon in 1745. He made significant contributions to the study of plant taxonomy and is credited with describing several new species.
Moving into the 19th century, the Dufraine surname was also present in other parts of Europe. For instance, in the Netherlands, there was a Dutch painter named Johannes Dufraine, who was born in Amsterdam in 1808 and is known for his landscape paintings.
Finally, in the 20th century, one of the most well-known individuals with the Dufraine surname was Marcel Dufraine, a French composer and conductor. Born in Paris in 1909, he gained recognition for his orchestral works and served as the principal conductor of the Orchestre National de France from 1965 to 1975.

The bar chart below shows how Dufraine 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 Dufraine surname at the time of the 2020 Census, not any inherent property of the name itself.
