Origin
The surname LERILLE is of French origin, originating in the northern regions of the country during the medieval period. It is thought to be derived from the Old French word "lerille," which referred to a small stream or brook, suggesting that the name may have initially been a topographic name for someone who lived near such a body of water.
One of the earliest recorded instances of the name can be found in the Cartulaire de l'abbaye de Saint-Père de Chartres, a medieval manuscript from the 12th century, which mentions a person named Robertus de Lerille. This suggests that the name was already established in the region by this time.
In the 13th century, there are records of a village called Lerille in the department of Pas-de-Calais, which may have been the place of origin for some bearers of the surname. The name is also similar to the village of Lirais in the department of Eure-et-Loir, indicating a potential connection.
Among notable individuals with the surname LERILLE throughout history are Jean-Baptiste LERILLE, a French mathematician and astronomer born in Coutances in 1766, who made significant contributions to the study of celestial mechanics. Another is Émile LERILLE, a French painter and illustrator born in Paris in 1823, known for his depictions of rural life and landscapes.
In the 16th century, there are records of a family named LERILLE residing in the town of Abbeville in Picardy, with one member, Jacques LERILLE, serving as a municipal official in 1542. During the same period, a Nicolas LERILLE is mentioned in the archives of the city of Amiens, working as a merchant in 1587.
Moving forward to the 17th century, a Charles LERILLE is documented as a prominent lawyer and legal scholar in Paris, publishing several treatises on French law between 1660 and 1685. In the 18th century, a family of LERILLE lived in the town of Reims, with one member, Pierre LERILLE, becoming a respected vintner and winemaker in the region.
While the surname LERILLE is not among the most common in France today, it has a rich history spanning several centuries, with bearers of the name hailing from various regions and occupations, contributing to the cultural and intellectual fabric of the country over time.
Demographics
Among Census respondents with the surname Lerille, the largest self-reported group is White at 93.1%. The next largest groups are Hispanic (5.9%) and Two or More Races (1.0%).
The bar chart below shows how Lerille 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 Lerille 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.
