Origin
The surname Langteau has its origins in France, with records dating back to the 16th century. It is believed to have derived from the Old French word "langetau," which referred to a long and narrow strip of land or a ditch. This suggests that the name may have initially been a descriptive term for someone who lived near such a geographical feature.
One of the earliest recorded instances of the name can be found in the village of Vaudoy, in the Burgundy region of France, where a family by the name of Langteau is mentioned in a local census from 1587. The name also appears in various church records and administrative documents from the 17th and 18th centuries in the nearby towns of Dijon and Beaune.
In the 19th century, a notable bearer of the name was Jean-Baptiste Langteau (1798-1873), a French painter known for his landscapes and portrayals of rural life. His works can be found in several prominent museums across France.
Another individual of note was Pierre Langteau (1832-1911), a French architect who played a significant role in the renovation and restoration of several historic buildings in Paris, including the iconic Notre-Dame Cathedral.
Across the Atlantic, one of the earliest recorded instances of the Langteau name in North America dates back to the late 18th century, when Jean-Marie Langteau (1767-1842) emigrated from France to Quebec, Canada. He settled in the Beauce region and became a prominent figure in the local community, serving as a magistrate and landowner.
In the United States, the name Langteau can be traced back to the early 19th century, with records indicating that a family by that name had settled in the state of Louisiana, likely originating from the French-speaking regions of Canada or directly from France.
Among the notable American bearers of the Langteau name was Alexander Langteau (1854-1932), a successful businessman and entrepreneur who founded the Langteau Lumber Company in New Orleans, which played a significant role in the city's economic growth during the late 19th and early 20th centuries.
While not as widespread as some other surnames, the name Langteau has left its mark on various parts of the world, with a rich history that spans several centuries and includes individuals from diverse backgrounds and professions.
Demographics
Among Census respondents with the surname Langteau, the largest self-reported group is White at 89.4%. The next largest groups are Hispanic (5.3%) and Two or More Races (2.7%).
The bar chart below shows how Langteau 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 Langteau surname at the time of the 2020 Census, not any inherent property of the name itself.
