Origin
The surname GUNDLACH is of German origin, deriving from the Germanic personal name Gundlach, which itself is a compound of the elements "gund" meaning "battle" and "lach" meaning "play" or "sport." It likely emerged during the Middle Ages, between the 5th and 15th centuries, in the regions that now comprise modern-day Germany.
One of the earliest recorded instances of the GUNDLACH surname can be found in the Codex Diplomaticus, a collection of historical documents from the region of Westphalia, Germany, dating back to the 13th century. The name appears in various spellings, including Gundlach, Gundlachs, and Gundlache, throughout these ancient records.
In the 14th century, a knight named Konrad Gundlach is mentioned in the chronicles of the city of Nuremberg, suggesting that the name was associated with nobility during that time period. Additionally, the town of Gundlach, located in the state of Saxony-Anhalt, Germany, may have derived its name from an early bearer of the GUNDLACH surname, although the exact origins of the place name are unclear.
Notable individuals with the GUNDLACH surname throughout history include:
1. Johann Gundlach (1638-1706), a German composer and organist who served as Kapellmeister in the court of the Margraves of Brandenburg-Ansbach.
2. Christian Gundlach (1759-1839), a German theologian and philosopher who taught at the University of Marburg.
3. Ernst Gundlach (1834-1908), a German botanist and naturalist who conducted extensive research on the flora of Cuba and Puerto Rico.
4. Johann Gundlach (1855-1931), a German-American optician and founder of the Gundlach-Manhattan Optical Company, known for developing high-quality camera lenses and telescopes.
5. Jörg Michael Gundlach (born 1957), a German mathematician and professor at the University of Bonn, known for his contributions to differential geometry and global analysis.
While the GUNDLACH surname has its roots in Germany, it has since spread to other parts of the world through emigration, particularly to North America and other regions with significant German diaspora populations.
Demographics
Among Census respondents with the surname Gundlach, the largest self-reported group is White at 92.9%. The next largest groups are Two or More Races (3.7%) and Hispanic (2.2%).
The bar chart below shows how Gundlach 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 Gundlach surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Gundlach (2000, 2010, 2020).
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.
