Origin
Meaning and origin of Dupee
The surname DUPEE is believed to have originated in France during the medieval period. It is thought to be a variant spelling of the French surname Dupuis, which is derived from the Old French words "du" meaning "of" and "puy" meaning "a hill or mound".
This suggests that the name DUPEE may have initially referred to someone who lived near or on a hill or mound. The earliest known records of the name date back to the 13th century in the region of Normandy, France.
One of the earliest recorded instances of the name DUPEE can be found in a document from the year 1287 in the town of Rouen, where a man named Jean DUPEE is mentioned as a local landowner. Another early record is from a tax roll in the village of Évreux in 1312, listing a family with the surname DUPEE.
The name DUPEE also appears in the Domesday Book, a manuscript recording landholdings in England after the Norman Conquest of 1066. This suggests that some individuals with the surname may have migrated from France to England during this period.
Notable individuals with the surname DUPEE include Jacques DUPEE (1586-1648), a French merchant and explorer who was one of the first Europeans to establish trade relations with the Native American tribes of present-day Canada. Another noteworthy figure is Marie DUPEE (1698-1784), a French noblewoman and philanthropist who founded several orphanages and schools in Paris.
In the 18th century, there was a prominent family of clockmakers in England named DUPEE, including John DUPEE (1742-1812) and his son William DUPEE (1772-1835), whose intricate timepieces were highly sought after by the British aristocracy.
Other notable individuals with the surname DUPEE include the French artist Paul DUPEE (1856-1925), known for his landscapes and portraits, as well as the American writer and critic James DUPEE (1923-2005), who was a influential figure in the literary world during the mid-20th century.

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 Dupee surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?
