Origin
Meaning and origin of Ardoin
The surname ARDOIN originated in France, specifically in the Normandy region, during the Middle Ages. It is believed to have derived from the Old French word "ardre," meaning "to burn," or the place name "Ardoin," a small village in Normandy.
One of the earliest recorded instances of the name ARDOIN can be found in the Domesday Book, a comprehensive survey of England commissioned by William the Conqueror in 1086. This suggests that individuals bearing this surname may have accompanied Norman settlers to England following the Norman Conquest of 1066.
In the 12th century, a notable figure named Guillaume ARDOIN was mentioned in various French historical records as a prominent landowner and knight. Another individual, Jean ARDOIN, born around 1320, was a respected scholar and author who wrote several treatises on philosophy and theology.
During the 16th century, the ARDOIN family had established a presence in the Bordeaux region of southwestern France. Pierre ARDOIN (1510-1585) was a renowned winemaker whose vineyards produced some of the finest wines in the region at that time.
In the 17th century, a branch of the ARDOIN family migrated to the French colony of Acadia, which is now part of eastern Canada. One notable figure from this period was Marie ARDOIN (1675-1744), who played a crucial role in preserving Acadian culture and traditions during the expulsion of the Acadians by the British in 1755.
In the 19th century, Louis ARDOIN (1825-1892) was a prominent figure in the French Revolution of 1848. He was a passionate advocate for worker's rights and social reforms, and his writings inspired many political movements of that era.
While the surname ARDOIN is more commonly found in France and French-speaking regions, it has also spread to other parts of the world due to immigration and migration patterns. However, the origins and historical significance of this name remain firmly rooted in its French heritage.

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

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Ardoin (2000, 2010, 2020).
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.
