Origin
Meaning and origin of Jeanlouis
The surname JEANLOUIS has its origins in France, dating back to the medieval period. It is a double-barreled surname, formed by combining the French first names "Jean" and "Louis." This naming practice was common among the French nobility and upper classes during the Middle Ages and Renaissance.
The name JEANLOUIS likely emerged in the northern regions of France, particularly in the areas around Paris and Normandy. It may have been derived from the Old French words "jehan" and "luis," which were variants of the names Jean and Louis. These names have ancient roots, with Jean originating from the Hebrew name Yohanan, meaning "God is gracious," and Louis stemming from the Frankish name Chlodovech, meaning "famous warrior."
One of the earliest recorded instances of the surname JEANLOUIS can be found in the Livre des Fiefs du Duché de Normandie, a medieval feudal survey from the 13th century. This document lists several individuals with the surname JEANLOUIS, indicating that the name was well-established in Normandy by that time.
During the Renaissance, the JEANLOUIS family gained prominence in the region of Île-de-France, which surrounds Paris. Notable figures from this period include Jacques JEANLOUIS (1525-1598), a renowned scholar and humanist who served as a tutor to the children of King Henry II of France.
In the 17th century, the JEANLOUIS name appeared in various historical records, such as parish registers and tax rolls. One notable individual was Marie JEANLOUIS (1642-1718), a noblewoman from the town of Châteaudun, who played a significant role in supporting the arts and culture during the reign of Louis XIV.
As the French colonial empire expanded, the JEANLOUIS name spread to other parts of the world. One notable figure was Pierre JEANLOUIS (1710-1789), a French explorer and cartographer who mapped vast territories in North America and the Caribbean.
During the French Revolution, the JEANLOUIS family faced persecution due to their noble status. However, some members managed to survive and continue the family line. One such individual was Antoine JEANLOUIS (1772-1835), a military officer who fought in the Napoleonic Wars and later became a respected landowner in the Burgundy region.
Throughout the 19th and early 20th centuries, the JEANLOUIS name remained prominent in various fields, including literature, politics, and academia. Notable figures include the writer and philosopher Marie-Thérèse JEANLOUIS (1830-1905), the politician and diplomat Paul JEANLOUIS (1865-1932), and the renowned linguist and educator Jacques JEANLOUIS (1893-1971).

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 Jeanlouis surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
