Origin
Meaning and origin of Demenge
The surname DEMENGE is of French origin, originating in the northeastern region of France during the medieval period. It is derived from the Middle French word "demenger," which means "to reside" or "to dwell." This suggests that the name may have originally been given to someone who moved from one place to another or established a new residence.
One of the earliest recorded instances of the surname DEMENGE can be found in the archives of the city of Metz, located in the Lorraine region of France. In a document dated 1387, a certain Jehan Demenge is mentioned as a resident of the city. This suggests that the name was already well-established in the area by the late 14th century.
In the 15th century, the name appears in various records from the neighboring regions of Alsace and Champagne. For example, a Nicolas Demenge is recorded as living in the village of Bouxières-aux-Dames in Alsace in 1472. This indicates that the name had spread beyond its original area of origin by this time.
One notable bearer of the DEMENGE surname was Jean Demenge, a French painter and engraver who lived in the 17th century (1636-1689). He was born in the town of Toul in Lorraine and is known for his religious works, many of which can be found in churches throughout the region.
Another historical figure with the DEMENGE surname was François Demenge, a French architect who lived in the 18th century (1737-1794). He was responsible for the design and construction of several notable buildings in the city of Nancy, including the Hôtel des Fermes and the Porte de la Craffe.
In the 19th century, the DEMENGE surname can be found in several places across France, including the regions of Lorraine, Champagne, and Alsace. One notable bearer from this time period was Eugène Demenge, a French politician and lawyer who was born in Épinal in 1853 and served as a member of the Chamber of Deputies for the department of Vosges.
While the DEMENGE surname is primarily associated with northeastern France, it has also been recorded in other parts of Europe, likely due to migration and intermarriage. For instance, there are records of individuals with the surname in Germany, Belgium, and even as far as Russia, where it may have been adapted to different spellings or forms.

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