Origin
The surname LAVALLIERE originated in France during the Middle Ages. It is believed to be derived from the Old French "la vallière," meaning "the valley," likely referring to someone who lived in or near a valley.
The name first appeared in official records in the 11th century, with the earliest known reference being a nobleman named Robert de la Valliere, who lived in the Normandy region of France in the late 11th century.
In the 12th century, the name was further documented in the Cartulaire de Cluny, a collection of charters and documents from the famous Cluny Abbey in Burgundy, France. One entry from 1156 mentions a certain Henri de la Valliere, a landowner in the region.
During the Hundred Years' War between England and France in the 14th and 15th centuries, the LAVALLIERE name gained prominence with the exploits of Jean de la Valliere, a French military commander who fought bravely against the English forces. Born around 1380, he was known for his defense of the city of Rouen in 1419.
In the 16th century, the LAVALLIERE surname spread to other parts of France, with records showing branches of the family in regions such as Brittany and Provence. A notable bearer of the name during this time was Louise de la Vallière, a celebrated French courtier and the mistress of King Louis XIV. Born in 1644, she was known for her beauty and her influential role at the court of Versailles.
Over the centuries, the LAVALLIERE name has produced several other notable individuals, including François de la Vallière (1617-1680), a French nobleman and military leader, and Louis-César de la Baume Le Blanc, Duc de La Vallière (1708-1780), a French aristocrat and statesman.
In the 19th century, the LAVALLIERE name gained literary recognition with the French author and playwright Auguste Maquet, whose full name was Auguste-Édouard-Pierre Maquet de la Valliere (1813-1888). He is best known for his collaboration with Alexandre Dumas on novels like "The Three Musketeers" and "The Count of Monte Cristo."
Demographics
Among Census respondents with the surname Lavalliere, the largest self-reported group is White at 80.9%. The next largest groups are Black (10.9%) and Hispanic (8.2%).
The bar chart below shows how Lavalliere 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 Lavalliere 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.
