Origin
Meaning and origin of Duprey
The surname Duprey has its origins in France, specifically in the northern region of Normandy, where it first emerged in the early Middle Ages. The name is thought to be derived from the Old French words "du" meaning "of" and "pré" meaning "meadow" or "field," suggesting that the earliest bearers of this surname likely lived in or near a meadow or field.
One of the earliest recorded instances of the surname Duprey can be found in the Domesday Book, a comprehensive survey of land ownership in England commissioned by William the Conqueror in 1086. This indicates that individuals bearing this name may have accompanied the Norman invaders to England following the conquest in 1066.
During the 13th century, a notable figure named Guillaume Duprey was documented as a prominent landowner in the village of Coutances, Normandy. His descendant, Jean Duprey (c. 1320-1395), was a respected scholar and theologian who served as a canon in the cathedral of Rouen.
In the 16th century, the Duprey family established themselves in the region of Brittany, where Pierre Duprey (1522-1592) gained recognition as a skilled merchant and trader. His son, Jacques Duprey (1558-1624), was a renowned architect who contributed to the construction of several notable buildings in the city of Rennes.
Another notable individual with the surname Duprey was Marie-Anne Duprey (1703-1768), a French botanist and naturalist who made significant contributions to the study of plant life in the Caribbean. Her extensive collection of specimens and detailed records were invaluable resources for researchers in the 18th century.
Over the centuries, variations in the spelling of the surname have been observed, including Dupré, Duprey, and Duprei, reflecting regional linguistic differences and the evolution of the French language.

The bar chart below shows how Duprey 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 Duprey 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 Duprey (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.
