Origin
The surname Knepprath has its origins in Germany, tracing back to the Middle Ages. It is derived from the Old German words "Kneppe," meaning knob or button, and "Rath," which can be translated as counsel or advice. This combination suggests that the name may have originally referred to a person who was a craftsman or artisan, perhaps specializing in the production of buttons or similar items.
One of the earliest known references to the Knepprath name can be found in the records of the town of Koblenz, located in the Rhineland region of Germany, dating back to the 14th century. This suggests that the name may have originated in this area, which was historically a center of trade and craftsmanship.
In the 16th century, a notable figure bearing the Knepprath name was Hans Knepprath (1497-1567), a master blacksmith and metalworker from the city of Nuremberg. His work, which included intricate ironwork and decorative pieces, was renowned throughout the region and helped to establish the Knepprath name as a symbol of skilled craftsmanship.
As the centuries passed, the Knepprath name spread across various parts of Germany and into neighboring regions. In the 18th century, Johann Knepprath (1725-1803), a scholar and linguist from the town of Göttingen, gained recognition for his contributions to the study of ancient languages and manuscripts.
Another notable figure was Maria Knepprath (1839-1912), a philanthropist and social reformer from Berlin. She dedicated her life to improving the living conditions of impoverished families and establishing educational programs for underprivileged children. Her efforts earned her widespread admiration and helped to further the Knepprath name's association with service and compassion.
In the 20th century, the Knepprath name continued to be carried by individuals who made their mark in various fields. For example, Karl Knepprath (1901-1985) was a renowned architect known for his innovative designs and contributions to the modernist movement in Germany.
Throughout its history, the surname Knepprath has maintained a strong connection to its German roots, while also spreading to other parts of the world through migration and cultural exchange.

The bar chart below shows how Knepprath 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 Knepprath 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.
