Origin
The surname LEBREUX originated in France, specifically in the northern regions of the country, and can be traced back to the Middle Ages. The name is derived from the Old French word "lebreux," which means "leper" or someone affected by leprosy.
During the Middle Ages, leprosy was a widespread and feared disease, and those afflicted were often segregated from society and forced to live in leper colonies or leper houses. The name LEBREUX likely emerged as a way to identify individuals or families who had been affected by the disease.
One of the earliest recorded references to the name LEBREUX can be found in the Domesday Book, a comprehensive survey of landholdings in England commissioned by William the Conqueror in 1086. The Domesday Book mentions a landowner named Radulfus le Lebreux, suggesting that the name was already in use by the late 11th century.
In the 13th century, a French nobleman named Jean LEBREUX was recorded as a participant in the Fourth Crusade, which aimed to recapture the Holy Land from Muslim rule. Jean LEBREUX is believed to have been born around 1180 and died sometime in the early 1200s.
Another notable figure with the surname LEBREUX was Jacques LEBREUX, a French painter and engraver who lived from 1619 to 1696. He was known for his religious paintings and his engravings depicting scenes from the Bible.
In the 18th century, a French philosopher and writer named Pierre LEBREUX (1720-1785) gained recognition for his works on ethics and moral philosophy. He was a critic of the French Revolution and advocated for a more moderate approach to social and political reform.
One of the earliest recorded instances of the LEBREUX surname in the Americas can be found in the records of the French colony of Acadia (now part of eastern Canada). In the late 17th century, a family with the surname LEBREUX was among the early settlers in the region.
Over time, the name LEBREUX has undergone various spelling variations, including Lebreux, Lebreaux, and Lebreu. Some of these variations may have been influenced by regional dialects or changes in pronunciation.
Demographics
Among Census respondents with the surname Lebreux, the largest self-reported group is White at 92.4%. The next largest groups are Two or More Races (4.6%) and Hispanic (3.1%).
The bar chart below shows how Lebreux 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 Lebreux 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.
