Origin
The surname DELESDERNIER has its roots in France, originating in the late 16th or early 17th century. It is believed to be derived from the French phrase "de les derniers," which translates to "of the last ones" or "of the latest." This name may have been given to a family or individual who was among the last to settle in a particular area or region.
The earliest recorded instances of the DELESDERNIER surname can be found in various parish records and historical documents from the Normandy region of France. In the early 1600s, a family by the name of DELESDERNIER was documented in the town of Rouen, which was a prominent city known for its textile industry and trading port.
One notable figure bearing the DELESDERNIER name was Jacques DELESDERNIER, born in 1652 in Rouen. He was a merchant and trader who played a significant role in the city's economic affairs during the late 17th century. His son, Pierre DELESDERNIER (1684-1742), followed in his footsteps and became a respected member of the local mercantile community.
In the 18th century, the DELESDERNIER family expanded beyond Normandy, with some members settling in other regions of France, such as Brittany and Île-de-France. One such individual was François DELESDERNIER (1712-1789), a prominent lawyer and legal scholar who practiced in Paris.
As the name spread across France, it also found its way to other parts of Europe and eventually to the Americas through French colonization and migration. In 1765, a man named Jean-Baptiste DELESDERNIER (1740-1812) was recorded as one of the earliest settlers of French descent in the Louisiana Territory, which was then under Spanish rule.
Another notable figure was Marie-Antoinette DELESDERNIER (1775-1842), a French artist and painter who gained recognition for her portraits and landscapes during the late 18th and early 19th centuries. Her works were exhibited in several prestigious salons in Paris and are now housed in various art museums across Europe.
While the DELESDERNIER surname may not be as common today as it once was, it remains an intriguing part of French genealogical history, with its origins rooted in the vibrant cultural tapestry of Normandy and its subsequent expansion across France and beyond.
Demographics
Among Census respondents with the surname Delesdernier, the largest self-reported group is White at 92.5%. The next largest groups are Hispanic (4.7%) and Two or More Races (2.8%).
The bar chart below shows how Delesdernier 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 Delesdernier surname at the time of the 2020 Census, not any inherent property of the name itself.
