Origin
The surname Senez is believed to have originated in the Languedoc region of southern France during the medieval period. It is derived from the Old French word "senez," meaning "elder" or "wise one," suggesting that the name may have initially been given to someone who was respected for their wisdom and experience.
One of the earliest recorded instances of the name Senez can be found in the Livre Terrier de Trets, a land registry from the 14th century that documented landowners and their properties in the village of Trets, located near Aix-en-Provence. This document mentions a certain "Pierre Senez" as a landowner in the region.
The name Senez is also closely associated with the town of Senez, located in the Alpes-de-Haute-Provence department of southeastern France. This town, which dates back to ancient Roman times, was once the site of a significant medieval bishopric, and it is possible that some early bearers of the surname Senez were connected to this religious center.
In the 16th century, a notable figure named Jean Senez (1515-1589) was a French Protestant theologian and philosopher who played a significant role in the Reformation movement in France. He was a vocal critic of the Catholic Church and wrote several influential works defending the Protestant cause.
Another historical figure with the surname Senez was Jacques Senez (1658-1734), a French architect and engineer who was involved in the construction of several notable buildings in Paris, including the Palais-Royal and the Hôtel de Ville.
Moving forward in time, a prominent bearer of the Senez name was Auguste Senez (1838-1916), a French painter and illustrator who was known for his genre scenes depicting everyday life in Paris. His works are held in the collections of several major museums, including the Musée d'Orsay and the Musée des Beaux-Arts in Reims.
In the 20th century, Pierre Senez (1907-1987) was a French actor and theater director who made significant contributions to the development of modern French theater. He founded the renowned Théâtre de la Huchette in Paris, which remains an important venue for avant-garde and experimental productions to this day.
While the surname Senez is not among the most common in France, it has a rich history and can be traced back to the medieval period in the southern regions of the country, where it likely originated as a descriptive name reflecting wisdom and age.
Demographics
Among Census respondents with the surname Senez, the largest self-reported group is White at 78.6%. The next largest groups are Hispanic (12.5%) and Two or More Races (6.3%).
The bar chart below shows how Senez 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 Senez 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.
