Origin
Meaning and origin of Derouen
The surname DEROUEN is of French origin, originating in the Normandy region of northern France during the medieval period. The name is derived from the town of Rouen, which was an important city in the region and a center of trade and commerce.
The earliest recorded instances of the name can be found in the 12th century, when it was typically spelled as "de Rouen" or "de Roan". This spelling reflects the name's origins as a locational surname, indicating that the bearer or their ancestors were from the town of Rouen.
As the name spread beyond its initial geographic region, variations in spelling emerged, including DEROUEN, DeRouen, and DeRohan. These variations were likely influenced by regional dialects and the preferences of individual record-keepers.
One of the earliest documented individuals bearing this surname was Robert de Rouen, a Norman nobleman who participated in the Third Crusade in the late 12th century. Another notable figure was Jean de Rouen, a French architect who worked on the construction of the Amiens Cathedral in the 13th century.
In the 14th century, the name appeared in the rolls of the Hundred Years' War, with several soldiers and knights bearing the surname DEROUEN or its variants. One such individual was Guillaume DeRouen, a Norman knight who fought alongside King Edward III of England in the Battle of Crécy in 1346.
During the Renaissance period, the DEROUEN surname was associated with several notable figures in the arts and literature. François DeRouen was a French poet and playwright who lived in the 16th century, and his contemporary, Jacques DeRouen, was a renowned painter known for his portraits of the French nobility.
As the name spread across Europe, it also found its way to England and other parts of the British Isles. In the 17th century, there are records of a family named DEROUEN residing in the county of Essex, with one member, John DEROUEN, serving as a magistrate in the town of Colchester.
Throughout the centuries, the DEROUEN surname has been carried by individuals from various walks of life, including merchants, artisans, and scholars. While the name has its roots in the Normandy region of France, it has since become a part of the cultural fabric of many nations and communities around the world.

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

Does the Census include every surname?
No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
