Origin
The surname KEPPER has its origins in Germany, dating back to the 16th century. It is believed to be derived from the German word "kupper," which means "coppersmith" or "copper worker." This suggests that the earliest bearers of this surname may have been involved in the copper trade or metalworking industry.
The name KEPPER was first recorded in the town of Bamberg, Bavaria, in the early 1500s. It is thought to have spread throughout the region as families migrated and settled in different areas. Some variations of the spelling include Kepper, Keper, and Küpper.
One of the earliest recorded instances of the name KEPPER can be found in the parish records of St. Michael's Church in Bamberg, where a certain Hans Kepper was listed as a resident in 1531. Another notable early reference is in the town archives of Nuremberg, where a merchant named Jakob Kepper is mentioned in a trade document from 1567.
In the 17th century, the name KEPPER appears in various historical records across Germany. For instance, a farmer named Christoph Kepper is listed in the land registry of Kirchheim unter Teck in 1632. Additionally, a soldier named Johann Kepper is recorded as having served in the Thirty Years' War between 1618 and 1648.
One of the earliest and most prominent individuals with the surname KEPPER was Johannes Kepler (1571-1630), the renowned German astronomer and mathematician. Although the spelling of his surname differs slightly from KEPPER, it is believed to have a similar origin and meaning.
Other notable individuals with the surname KEPPER include:
1. Friedrich Kepper (1833-1899), a German architect and urban planner responsible for designing various buildings and public spaces in Berlin.
2. Christoph Kepper (1793-1869), a German painter and lithographer known for his landscapes and cityscapes.
3. Hans Kepper (1878-1945), a German businessman and industrialist who owned textile factories in Saxony.
4. Gerhard Kepper (1909-1991), a German writer and poet who was part of the literary movement known as "Innere Emigration" during the Nazi regime.
5. Wilhelm Kepper (1856-1923), a German botanist and professor at the University of Tübingen, known for his research on plant physiology and ecology.
While the surname KEPPER may have evolved and spread to other regions over time, its origins can be traced back to the German-speaking areas of Central Europe, where it was likely first adopted by those involved in the copper trade or metalworking professions.
Demographics
Among Census respondents with the surname Kepper, the largest self-reported group is White at 94.5%. The next largest groups are Hispanic (2.5%) and Two or More Races (2.5%).
The bar chart below shows how Kepper 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 Kepper surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
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.
