Origin
The surname DEROUSELLE has its origins in France, dating back to the early medieval period. It is believed to be derived from the Old French word "rouselle," which referred to a small stream or brook, possibly suggesting that the name's earliest bearers lived near or worked in an area with a small waterway.
One of the earliest recorded instances of the name can be found in the "Livre des métiers," a 13th-century French manuscript that documented various professions and trades. In this text, a person named Robert Derouselle is listed as a miller, lending credence to the theory that the name is connected to water sources.
In the 14th century, the name appeared in the "Rôles de l'Échiquier de Normandie," a collection of financial records from the Duchy of Normandy. This document mentions a certain Guillaume Derouselle, who was a landowner in the region.
During the 15th century, the surname Derouselle was found in the "Rôles des bans et arrière-bans du Poitou," a military census from the province of Poitou. This record lists several individuals bearing the name, indicating that the family had spread to various parts of France by that time.
One notable figure associated with the surname Derouselle was Jacques Derouselle (1540-1612), a French poet and playwright who was part of the Pléiade literary movement. His works, which included tragedies and pastoral poetry, were highly regarded during the Renaissance period.
Another individual of note was Marie-Anne Derouselle (1678-1755), a French painter and miniaturist who was active in the early 18th century. She was particularly known for her portraits and religious works, some of which can still be found in various museums and collections across Europe.
In the 19th century, the name Derouselle gained prominence in the field of agriculture with Pierre-Henri Derouselle (1816-1892), a French agronomist and writer who published several influential works on crop cultivation and farming techniques.
Other notable bearers of the surname include Louis-Philippe Derouselle (1892-1968), a French politician who served as a deputy in the National Assembly, and Jeanne Derouselle (1914-2002), a French resistance fighter during World War II who was awarded the Croix de Guerre for her bravery.
While the surname Derouselle is not among the most common in France today, its rich history and connection to various professions and individuals across different eras showcase the diversity and resilience of this name over the centuries.
Demographics
Among Census respondents with the surname Derouselle, the largest self-reported group is Black at 85.3%. The next largest groups are White (6.9%) and Two or More Races (6.0%).
The bar chart below shows how Derouselle 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 Derouselle surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
