Origin
The surname GRENET originated in France, specifically in the region of Normandy, during the Middle Ages. It is derived from the Old French word "grenet," which means "grange" or "granary." This suggests that the name may have been initially given to someone who lived near or worked in a granary or barn.
In the Domesday Book, a famous medieval manuscript recording landowners in England after the Norman Conquest, there are several entries for individuals with the surname GRENET or similar spellings, such as Grenete and Grenett. This indicates that the name was present in England as early as the 11th century, likely brought over by Norman settlers.
One of the earliest recorded instances of the name GRENET can be found in the Cartulary of the Abbey of Mont-Saint-Michel, a collection of medieval charters and documents from the famous abbey in Normandy. In this cartulary, a certain Guillaume GRENET is mentioned as a witness to a land transaction in the early 12th century.
Another notable historical figure bearing the GRENET surname was Jean GRENET, a French scholar and theologian born in the late 14th century (around 1380). He was a professor at the University of Paris and authored several works on theology and philosophy.
In the 15th century, there was a prominent family in the Burgundian Netherlands with the surname GRENET. One member, Jacques GRENET (c. 1420-1491), served as a diplomat and counselor to several dukes of Burgundy.
During the Renaissance period, a French poet named Claude GRENET (c. 1520-1592) gained recognition for his works in the French Renaissance style. He was a member of the famous literary circle known as the Pléiade, led by Pierre de Ronsard.
In the 17th century, a French historian and theologian named Jean GRENET (1620-1699) wrote extensively on the history of the Catholic Church and the lives of saints. His most notable work was a multi-volume compilation titled "Vies des Saints" (Lives of the Saints).
Demographics
Among Census respondents with the surname Grenet, the largest self-reported group is White at 74.1%. The next largest groups are Hispanic (25.0%) and Two or More Races (0.9%).
The bar chart below shows how Grenet 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 Grenet 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.
