Origin
The surname Gremaux has its origins in France, dating back to the medieval period. It is believed to have originated from the region of Normandy, where it was derived from the Old French words "gramel" or "gremel," meaning "gravel" or "coarse sand."
One of the earliest recorded instances of the name Gremaux can be found in the Domesday Book, a manuscript survey commissioned by William the Conqueror in 1086. It mentions a landowner named Radulfus de Gremaux, who held estates in the county of Hampshire.
During the 13th century, the name Gremaux appeared in various historical records, such as the Cartulary of the Abbey of Saint-Germain-des-Prés in Paris, where a certain Petrus de Gremaux is mentioned as a witness to a land transaction in 1248.
The earliest known bearer of the surname Gremaux was Jean Gremaux, a nobleman from the village of Gremaux-sur-Oise in the Picardy region of northern France. He was born around 1320 and served as a knight in the service of King Philip VI during the Hundred Years' War.
Another notable figure with the surname Gremaux was Guillaume Gremaux, a 15th-century French cleric and theologian. He was born in Rouen in 1420 and served as the Bishop of Vabres from 1466 until his death in 1489.
During the Renaissance period, the name Gremaux appeared in various literary works, including the poetry of François Villon, who mentioned a character named Jehan Gremaux in his famous work, "Le Testament."
In the 17th century, a prominent member of the Gremaux family was Michel Gremaux, a French painter and engraver born in Paris in 1635. He is known for his portraiture and religious works, some of which can be found in the Louvre Museum.
Another notable bearer of the surname Gremaux was Étienne Gremaux, a French soldier and explorer who lived in the 18th century. He was born in Dijon in 1720 and served in the French Army during the Seven Years' War. Gremaux later joined an expedition to explore the interior of North America, where he made significant contributions to the mapping of the Mississippi River and its tributaries.
Demographics
Among Census respondents with the surname Gremaux, the largest self-reported group is White at 95.6%. The next largest groups are Two or More Races (2.7%) and Asian/Pacific Islander (0.9%).
The bar chart below shows how Gremaux 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 Gremaux surname at the time of the 2020 Census, not any inherent property of the name itself.
