Origin
Meaning and origin of Laderoute
The surname LADEROUTE has its origins in France, dating back to the 16th century. It is believed to have originated from the French phrase "la de route," which translates to "the road" or "the route." This suggests that the name may have been initially associated with individuals who lived along a particular road or route.
One of the earliest recorded instances of the LADEROUTE name can be found in historical records from the Normandy region of France. In the mid-1500s, a family bearing this surname was documented in the town of Rouen, which was a significant commercial and cultural center at the time.
During the 17th century, the LADEROUTE name began to appear in various parish records and tax rolls throughout northern France. This indicates that the name had gained some prominence and was becoming more widely distributed across the region.
Interestingly, there are mentions of the LADEROUTE name in several historical manuscripts and documents from the 18th century. One notable example is the memoir of Jacques LADEROUTE (1722-1798), a French merchant who traveled extensively and documented his experiences in detail.
As the LADEROUTE family expanded and migrated, the name underwent various spelling variations. Some of the alternative spellings included Laderot, Laderotte, and Laderoutte, which were likely influenced by regional dialects and scribal errors.
One of the earliest known individuals with the LADEROUTE surname was Pierre LADEROUTE (1650-1718), a farmer from the village of Évreux in Normandy. His descendants went on to become respected landowners and businessmen in the region.
Another notable figure was Marie LADEROUTE (1785-1862), a French novelist and playwright who gained recognition for her works depicting the lives of ordinary people in rural France. Her novels, such as "Le Chemin de Traverse" (The Crossroad), were widely read and celebrated during her time.
In the 19th century, the LADEROUTE name was carried across the Atlantic by French immigrants seeking new opportunities. One such individual was Jean-Baptiste LADEROUTE (1820-1892), who settled in Quebec, Canada, and established a successful trading business.
As the LADEROUTE family spread across different countries and continents, the name continued to evolve and adapt to local customs and languages. However, its French origins and association with routes and roads remained an integral part of its history and significance.

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