Origin
Meaning and origin of Archambault
The surname Archambault is of French origin, originating from the Old French personal name Archambalus or Archambaud, which is a compound of the Germanic elements arc, meaning "box" or "chest," and bald, meaning "bold" or "brave." The name likely emerged in the Middle Ages, possibly in the 9th or 10th century.
The surname is believed to have first appeared in the regions of Burgundy, Franche-Comté, and Champagne in eastern France. It is also found in neighboring areas of Switzerland and Belgium. Variations in spelling include Archambaud, Archambaut, and Archambeau.
One of the earliest recorded instances of the name Archambault can be found in the Domesday Book of 1086, which was a survey of land and property conducted in England by order of William the Conqueror. However, the reference is to a place name rather than a personal name.
In the 12th century, Archambault de Bourbon (c. 1109-1169) was a prominent French nobleman and the fourth Sire of Bourbon. He played a significant role in the Second Crusade and the Siege of Damascus in 1148.
Another notable figure was Étienne Archambault (c. 1290-1350), a French architect who worked on the construction of the Palais de la Cité in Paris, which was the royal residence of the French monarchs.
In the 16th century, Jacques Archambault (c. 1540-1620) was a French Catholic priest and author known for his works on moral theology and canon law.
During the 17th century, Louis Archambault (1615-1700) was a French military engineer and architect who designed fortifications and buildings in various parts of France and Canada.
In more recent times, Gérard Archambault (1899-1992) was a Canadian politician and lawyer who served as a member of the Senate of Canada from 1957 to 1974.

The bar chart below shows how Archambault 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 Archambault 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.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. 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.
