Origin
Meaning and origin of Bertaud
The surname Bertaud is of French origin, with roots dating back to the 12th century. It is believed to have originated from the region of Auvergne in central France. The name is derived from the Germanic elements "berht," meaning bright or illustrious, and "wald," meaning ruler or commander. Together, these elements form the compound "Bertwald," which later evolved into the modern spelling of Bertaud.
One of the earliest recorded instances of the name can be found in the Cartulaire de Brioude, a medieval manuscript from the Auvergne region. This cartulary, which dates back to the 12th century, includes several mentions of individuals bearing the name Bertaud, suggesting that the name was well-established in the area at that time.
During the 13th century, the name appeared in various historical records, including the Trésor des Chartes, a collection of royal charters and documents from the French monarchy. One notable individual from this period was Jean Bertaud, a prominent landowner and knight who served under King Louis IX (reigned 1226-1270).
In the 14th century, the name Bertaud gained further recognition with the rise of Jacques Bertaud (c. 1320-1389), a renowned French scholar and theologian. Bertaud served as the chancellor of the University of Paris and played a significant role in the intellectual and religious debates of his time.
The 16th century saw the emergence of another prominent figure bearing the Bertaud name – François Bertaud (1522-1594). He was a French poet and translator who gained recognition for his translations of ancient Greek and Latin works into French.
Throughout the centuries, the name Bertaud has been associated with various places and regions in France. For instance, the town of Bertaud-Vicomte in the Puy-de-Dôme department of Auvergne likely derives its name from an early bearer of the surname. Additionally, the village of Bertaucourt in the Somme department of northern France may trace its origins to a similar source.
Other notable individuals with the surname Bertaud include Marie-Anne Bertaud (1735-1814), a French painter and engraver who gained recognition for her portraits and etchings, and Pierre-Eugène Bertaud (1842-1924), a French sculptor known for his monumental works and public sculptures.
While the Bertaud surname has its roots in France, it has since spread to other parts of the world, carried by emigrants and descendants over the centuries. However, its origins and historical significance remain firmly rooted in the French regions of Auvergne and the surrounding areas, where the name first emerged and flourished.

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.

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