Origin
The surname Billodeau is of French origin, tracing its roots back to the northwestern region of France, particularly in the areas of Normandy and Brittany. It is believed to have emerged during the Middle Ages, around the 12th or 13th century.
The name Billodeau is thought to be derived from the Old French word "billot," which referred to a small log or piece of wood. This suggests that the name may have originally belonged to someone who worked with wood, such as a lumberjack, carpenter, or woodcutter.
Historical records indicate that variations of the name, such as Billaud, Billioud, and Billioud, appeared in various medieval documents from the region. However, no specific mentions of the Billodeau surname have been found in notable historical sources like the Domesday Book.
One of the earliest documented individuals with the Billodeau surname was Jean Billodeau, born in 1587 in the village of Saint-Malo, Brittany. He was a fisherman by trade and is recorded in the parish records of the time.
In the 17th century, a notable figure named Pierre Billodeau (1623-1699) was a merchant and shipowner in the port city of La Rochelle. He played a role in the maritime trade between France and its colonies in the Americas.
During the French Revolution, a soldier named Jacques Billodeau (1756-1832) fought in the revolutionary armies and later served under Napoleon Bonaparte. He rose to the rank of colonel and was awarded the Légion d'Honneur for his military service.
In the 19th century, a French sculptor named Louis-Auguste Billodeau (1818-1891) gained recognition for his work, particularly his sculptures adorning public buildings and monuments in Paris.
Another notable figure was Émilie Billodeau (1842-1920), a French educator and advocate for women's rights. She founded several schools in Paris and campaigned for equal educational opportunities for girls and women.
While the Billodeau surname originated in France, it eventually spread to other parts of the world, including Canada and the United States, due to migration and emigration.
Demographics
Among Census respondents with the surname Billodeau, the largest self-reported group is White at 93.8%. The next largest groups are Two or More Races (2.7%) and American Indian/Alaska Native (1.8%).
The bar chart below shows how Billodeau 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 Billodeau 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.
