Origin
Meaning and origin of Gillot
The surname Gillot is of French origin, stemming from the northern regions of France, particularly around the areas of Normandy and Brittany. It is believed to have emerged during the Middle Ages, likely derived from the Old French personal name "Gilo" or "Gilo(u)t," which itself is thought to be a diminutive form of the Germanic name "Gilo" or "Gilo(u)."
One of the earliest recorded instances of the surname Gillot can be found in the Domesday Book of 1086, where it appears as "Gilot." This reference suggests that the name had already been established in parts of Normandy prior to the Norman Conquest of England in 1066.
During the 13th century, various spellings of the name began to appear in historical records, including "Gilot," "Gillot," and "Gyllot." This variation in spelling was not uncommon during this era, as standardized spelling conventions had not yet been established.
In the 14th century, the surname Gillot can be found in records from the region of Burgundy, where it is believed to have been associated with a locality or place name, possibly derived from the Old French word "gille," meaning "a young man" or "a servant."
One notable figure bearing the Gillot surname was Jacques Gillot (1670-1737), a French painter and engraver from the town of Châlons-sur-Marne. He was known for his intricate etchings and was a member of the Royal Academy of Painting and Sculpture in Paris.
Another prominent individual with the Gillot surname was Claude Gillot (1673-1722), a French painter and printmaker from the village of Langres. He was a pioneer of the Rococo style and served as a teacher to several notable artists, including Antoine Watteau.
In the 18th century, the Gillot name appeared in records from the French colony of Saint-Domingue (now Haiti), where it is believed that members of the family may have settled and established themselves in the Caribbean.
A notable figure from this era was Pierre Gillot (1730-1809), a French naval officer and explorer who commanded several voyages to the Indian Ocean and helped establish French colonies in the region.
During the 19th century, the Gillot surname gained prominence in the field of literature, with the French novelist and dramatist André Gillot (1833-1902) being one of the most notable figures of that time.
Another individual of note was Louis Gillot (1846-1920), a French sculptor and artist who was known for his works depicting scenes from everyday life in rural France.

The bar chart below shows how Gillot 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 Gillot surname at the time of the 2020 Census, not any inherent property of the name itself.

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
