Origin
The surname LAVANCE is believed to have originated in France during the medieval period. It is thought to derive from the Old French word "lavance," which meant "a stream" or "a small river." This suggests that the name may have initially referred to someone who lived near a stream or river, or perhaps even worked as a ferryman or boatman.
One of the earliest recorded instances of the name LAVANCE can be found in the Livre des Métiers, a 13th-century document that listed the various trades and professions in Paris. In this text, there is a mention of a "Jean Lavance," who was listed as a boatman operating on the Seine River.
In the 14th century, the name appeared in several historical records from the region of Normandy, where it was often spelled as "Lavaunce" or "Lavauns." This variation in spelling was common during this time period, as standardized spelling conventions had not yet been established.
During the 15th and 16th centuries, the name LAVANCE began to spread beyond France, with records indicating individuals bearing this surname living in parts of England and Scotland. One notable example is Robert LAVANCE, a merchant from Rouen, France, who settled in London in the late 1500s and became a prominent figure in the city's thriving wool trade.
Another notable figure bearing this surname was Jeanne LAVANCE, a French Protestant who fled religious persecution in the late 16th century and sought refuge in Geneva, Switzerland. She is noted in historical records for her efforts in establishing a safe haven for other Huguenot refugees.
In the 17th century, the LAVANCE surname appeared in several parish records in the English county of Dorset, where it is believed a branch of the family had settled. One such record from 1628 mentions the baptism of a child named William LAVANCE in the village of Wimborne Minster.
As the centuries progressed, the LAVANCE name continued to spread throughout Europe and eventually to other parts of the world, with individuals bearing this surname making their mark in various fields, including literature, politics, and the arts. Notable examples include the French poet and essayist André LAVANCE (1870-1935) and the British artist and illustrator Evelyn LAVANCE (1888-1967).
Demographics
Among Census respondents with the surname Lavance, the largest self-reported group is White at 78.0%. The next largest groups are Two or More Races (8.3%) and Hispanic (5.5%).
The bar chart below shows how Lavance 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 Lavance 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.

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.
