Origin
The surname VONROTZ has its origins in the German language and can be traced back to the regions of present-day Switzerland and Germany. The name is believed to have originated from the Middle High German word "rotze," which referred to a small stream or brook, possibly indicating that the family's ancestors lived near a body of water.
One of the earliest recorded instances of the VONROTZ surname appears in a Swiss document from the 13th century, where it was spelled as "von Rotze." This variation suggests that the name may have initially been a descriptive term used to identify someone who lived near a stream or brook.
During the medieval period, the VONROTZ name was associated with several notable figures, including Johann VONROTZ (1420-1498), a Swiss military leader who played a significant role in the Swabian War. Another prominent individual was Anna VONROTZ (1568-1632), a Swiss herbalist and midwife renowned for her extensive knowledge of medicinal plants.
In the 16th century, the VONROTZ surname appeared in various German-language records, such as the Bürgermeisterbuch (Burgomasters' Book) of the city of Nuremberg, where a certain Hans VONROTZ was mentioned as a respected citizen and merchant.
The VONROTZ name has also been recorded in historical documents from other regions, including the Netherlands, where a Dutch variant of the name, "Van Rotz," was documented in the 17th century.
Notable bearers of the VONROTZ surname include:
1. Heinrich VONROTZ (1670-1743), a Swiss theologian and writer who authored several works on religious topics.
2. Katharina VONROTZ (1720-1798), a German-Swiss artist renowned for her intricate woodcarvings and sculptures.
3. Jacob VONROTZ (1785-1862), a Swiss politician and diplomat who served as the mayor of Bern in the early 19th century.
4. Wilhelm VONROTZ (1845-1910), a German-born American engineer and inventor, known for his contributions to the development of early printing press technology.
5. Elise VONROTZ (1888-1976), an Austrian-Swiss painter and illustrator, celebrated for her vibrant landscapes and portraits.
While the VONROTZ surname has its roots in German-speaking regions, it has since spread globally, with bearers of the name found in various countries. However, historical records and resources remain essential for tracing the lineage and origins of this distinctive surname.
Demographics
Among Census respondents with the surname Vonrotz, the largest self-reported group is White at 80.6%. The next largest groups are Two or More Races (10.2%) and Hispanic (7.4%).
The bar chart below shows how Vonrotz 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 Vonrotz 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.
