Origin
Meaning and origin of Collupy
The surname Collupy is believed to have originated in the region of Languedoc in southern France during the early medieval period. It is derived from the Old French word "colup," which meant a small hill or mound. This suggests that the earliest bearers of this name likely lived near or on a small hill.
One of the earliest recorded instances of the Collupy name appears in the Livre Seigneurial, a feudal register compiled in the 13th century. The entry lists a certain Guilhem Collupy as a landowner in the village of Saint-Gervais-sur-Mare, near the city of Nîmes. This document provides evidence that the Collupy family had already established itself in the area by that time.
In the 14th century, the Collupy name began to spread beyond its original homeland. Records show a Pierre Collupy being granted citizenship in the city of Marseille in 1372, indicating that members of the family had migrated to other parts of southern France. By the 15th century, variations of the name, such as Colluppi and Colluppy, started appearing in Italian records, suggesting that some Collupys had made their way across the Mediterranean.
One of the most notable individuals bearing the Collupy name was Jean Collupy (1523-1588), a renowned painter and sculptor from the town of Arles. His works, including several religious frescoes and wooden statues, can still be found in churches throughout Provence. Another prominent Collupy was Renée Collupy (1678-1745), a renowned mathematician and astronomer who served as a tutor to the children of King Louis XIV.
As the Collupy family dispersed over the centuries, the name took on various forms in different regions. In Spain, for instance, it became Collupez, while in Italy it was often spelled Collupi. Despite these variations, the underlying meaning and origin of the name remained the same, tracing back to the small hills of Languedoc where the Collupys first emerged centuries ago.
Other noteworthy individuals with the Collupy surname include:
1. Étienne Collupy (1605-1677), a French poet and playwright known for his satirical works.
2. Marguerite Collupy (1720-1798), a prominent figure in the French Revolution and a pioneer of women's rights.
3. Lorenzo Collupi (1824-1892), an Italian sculptor whose works adorned many public buildings in Rome.
4. Henri Collupez (1867-1936), a Spanish explorer and naturalist who led several expeditions to South America.
5. Yvette Collupy (1912-2001), a French author and journalist who wrote extensively about the Resistance during World War II.

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