Origin
Meaning and origin of Euper
The surname Euper is believed to have originated in Germany, with the earliest recorded instances dating back to the 16th century. The name is thought to be derived from the German word "Eup," which means "yew tree" or "yew wood." This suggests that the name may have originally been given to someone who lived near a prominent yew tree or worked with yew wood.
One of the earliest known records of the Euper name is found in a 1578 church register from the town of Aachen, in what is now western Germany. The register lists a family with the surname "Euper," indicating that the name was already established in the region by that time.
In the 17th century, the Euper name appears in several historical documents from the Rhineland area of Germany. For example, a 1632 tax record from the city of Cologne includes a merchant named Johann Euper, suggesting that members of the family had achieved some level of prosperity and social standing.
As the centuries passed, the Euper name spread to other parts of Germany and beyond. In the 18th century, there are records of Eupers living in various towns and villages throughout the German states, as well as in neighboring countries like the Netherlands and Switzerland.
One notable bearer of the Euper name was Heinrich Euper (1772-1845), a German composer and organist who served as the Kapellmeister (music director) at the court of the Prince of Nassau-Weilburg. His compositions, which included sacred works and instrumental pieces, were well-regarded in his time.
Another significant figure with the Euper surname was Johann Euper (1810-1879), a German artist and lithographer who was particularly skilled in portraiture. His works can be found in several museums and private collections throughout Germany and Europe.
In the 19th century, the Euper name also appeared in historical records from the United States, suggesting that members of the family had emigrated from Germany to America. One early example is Christian Euper (1820-1892), a farmer and landowner in Pennsylvania who had immigrated from the Rhineland region of Germany.
Other notable Eupers throughout history include Johann Peter Euper (1838-1912), a German-American brewer and businessman who founded the Euper Brewing Company in St. Louis, Missouri, and Gerhard Euper (1867-1938), a German theologian and religious scholar who served as a professor at the University of Bonn.

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 Euper 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.
