Origin
Meaning and origin of Billeaudeau
The surname BILLEAUDEAU is of French origin, originating in the northwestern regions of France during the medieval period. It is believed to be derived from the old French words "billaud" or "bille," which referred to a type of billet or small log of wood. The suffix "-eau" was a common diminutive ending, suggesting the name may have been an occupational one, referring to someone who worked with small logs or billets of wood.
One of the earliest recorded instances of the name can be found in the 13th-century manuscript known as the "Rôles de l'Échiquier de Normandie," which lists a certain "Guillaume Billeaudeau" from the town of Caen in Normandy. This suggests the name may have originated in the Normandy region before spreading to other areas of France.
During the 14th and 15th centuries, variations of the name such as "Billaudeau" and "Billaudel" appear in records from various parts of France, including the regions of Poitou, Anjou, and Touraine. Some of these records mention individuals with the name holding positions as merchants or craftsmen, potentially supporting the theory of an occupational origin.
In the 16th century, the name BILLEAUDEAU appears in the records of the city of La Rochelle, an important maritime center on the Atlantic coast of France. One notable individual from this time was Jacques BILLEAUDEAU, a merchant and shipowner who lived from approximately 1530 to 1598.
Moving into the 17th century, the name can be found in the records of the town of Saint-Maixent in the Poitou region. A certain Pierre BILLEAUDEAU, born around 1610, was a prominent landowner and local official in this area.
Another notable figure was François BILLEAUDEAU, born in 1662 in the town of Fontenay-le-Comte in the Vendée region. He served as a lawyer and judge and was instrumental in the codification of local laws and customs in his area.
As the name spread across France, it also found its way to the French colonies in North America, where individuals bearing the surname BILLEAUDEAU can be found in the records of settlements such as Quebec and Acadia (present-day Maritime provinces of Canada).
Throughout its history, the surname BILLEAUDEAU has been borne by a diverse range of individuals, from merchants and landowners to lawyers and judges, reflecting the diverse origins and occupations of those who carried this name.

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.
