Origin
Meaning and origin of Maddoux
The surname MADDOUX is believed to have originated in France, specifically in the region of Normandy, during the medieval period. It is thought to be derived from the Old French term "madeuc," which means "small" or "little." This suggests that the name may have initially been a nickname given to someone of small stature or a younger child.
One of the earliest recorded instances of the name MADDOUX can be found in the Domesday Book, which was a comprehensive survey of England commissioned by William the Conqueror in 1086. The entry mentions a landowner named Robert Maddoux, who held lands in the county of Somerset.
In the 13th century, there are records of a nobleman named Gilles MADDOUX, who was a prominent figure in the court of King Louis IX of France. Gilles MADDOUX was known for his military prowess and participated in the Seventh Crusade to the Holy Land.
During the 16th century, the name MADDOUX was particularly prevalent in the town of Rouen, in northern France. Historical records from that time mention a family of merchants and traders bearing the name MADDOUX, who were involved in the thriving textile industry of the region.
One notable individual with the surname MADDOUX was Jean-Baptiste MADDOUX (1701-1778), a French philosopher and writer who was renowned for his critical works on the Enlightenment thinkers of his time. He was born in Marseille and spent much of his life in Paris, where he gained recognition for his intellectual contributions.
In the 19th century, the name MADDOUX was associated with a prominent family of vintners in the Bordeaux region of France. The MADDOUX family owned several vineyards and played a significant role in the development of the local wine industry. One of the most renowned members of this family was Alexandre MADDOUX (1825-1901), whose wines were highly sought after and received numerous accolades.
Another notable figure with the surname MADDOUX was Émilie MADDOUX (1872-1962), a French artist and sculptor who gained recognition for her innovative use of materials and her portrayal of historical and mythological themes. Her works were exhibited in prestigious galleries across Europe and are now housed in various museums around the world.

The bar chart below shows how Maddoux 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 Maddoux surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?
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.
