One of the earliest recorded instances of the name Lesperance can be found in the Domesday Book of 1086, a comprehensive record of landholders commissioned by William the Conqueror. The name is listed as "Le Esperance", referring to a landowner in the county of Sussex, England.
During the Middle Ages, variations of the spelling included "L'Esperaunce", "Lesperauns", and "Lesperaunce". These variations were common due to the inconsistencies in spelling and record-keeping at the time.
In the 14th century, the name Lesperance appeared in the Hundred Rolls of Cambridgeshire, a census-like record of landowners and their holdings. This document references a Robert Lesperance, who held land in the village of Bottisham.
One notable bearer of the name was Jean Lesperance, a French explorer and fur trader who lived in the late 16th century. He was among the first Europeans to explore the Great Lakes region of North America and establish trade routes with the indigenous peoples.
Another prominent figure was François Lesperance, a French soldier and military engineer born in 1635. He served under Louis XIV and played a crucial role in the construction of fortifications across France and its territories.
In the 18th century, Jacques Lesperance (1723-1796) was a French architect renowned for his work on several churches and public buildings in Paris and the surrounding regions.
The name Lesperance has also been associated with various place names, such as Lesperance Creek in Montana, USA, and Lesperance Lake in Ontario, Canada, both named after early settlers or explorers bearing the surname.
One of the most famous individuals with the name Lesperance was Pierre Lesperance (1856-1923), a Canadian politician and lawyer who served as a member of the House of Commons of Canada and played a significant role in the development of labor laws in the country.
Demographics
Among Census respondents with the surname Lesperance, the largest self-reported group is White at 74.1%. The next largest groups are Black (12.2%) and Hispanic (9.1%).
The bar chart below shows how Lesperance 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 Lesperance surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Lesperance (2000, 2010, 2020).
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.
