Origin
The surname LEBOUF has its origins in France, dating back to the medieval period. It is believed to have originated as a locational name, referring to a person from a place called Beaufort or Beufort, derived from the old French words "beau" meaning "beautiful" and "fort" meaning "strong" or "fortified."
The earliest recorded instances of the name can be traced back to the 13th century, with variations such as Le Beu, Le Bauf, and Le Bouf appearing in historical records and documents. One notable example is Robert Le Bauf, a landowner in Normandy who was mentioned in the Cartulaire de la Cathédrale de Bayeux in 1256.
The name LEBOUF also appeared in the famous Domesday Book, a comprehensive survey of landholdings in England commissioned by William the Conqueror in 1086. The entry refers to a nobleman named Gaufridus Le Bauf, who held lands in the county of Devon.
Historically, the LEBOUF name has been associated with several notable individuals. In the 15th century, Jean Le Bouf was a prominent merchant and ship owner in the coastal town of La Rochelle, France. His son, Pierre Le Bouf, served as a captain in the French navy during the reign of King Louis XII (1462-1515).
During the French Renaissance, the LEBOUF name gained prominence through the work of Claude Le Bouf (1524-1592), a renowned architect and engineer who designed several notable buildings in Paris, including the Hôtel de Sully and the Pont Neuf.
Another notable bearer of the name was François Le Bouf (1612-1679), a French Jesuit missionary who traveled to Canada and played a significant role in the early exploration and mapping of the Great Lakes region.
In the 18th century, the LEBOUF family produced several distinguished military officers, including General Charles-François Le Bouf (1739-1813), who served in the French Revolutionary Wars and the Napoleonic Wars.
Throughout its history, the LEBOUF surname has undergone various spelling variations, such as Le Boeuf, Le Bauf, and Le Beuf, reflecting regional dialects and scribal practices of the time. However, the core meaning and origins of the name have remained rooted in its locational and descriptive origins, representing the strong and fortified places from which the earliest bearers of the name hailed.
Demographics
Among Census respondents with the surname Lebouf, the largest self-reported group is White at 88.4%. The next largest groups are American Indian/Alaska Native (4.1%) and Two or More Races (3.3%).
The bar chart below shows how Lebouf 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 Lebouf surname at the time of the 2020 Census, not any inherent property of the name itself.
