Origin
The surname SCHONLAU is of German origin, with roots tracing back to the late medieval period. It likely originated in the regions of central or eastern Germany, where many place names and surnames were derived from descriptive terms related to the local landscape or geographic features.
SCHONLAU is believed to be a combination of two Old German words: "schön," meaning "beautiful" or "fair," and "lau," which could refer to a meadow, clearing, or forest glade. This suggests that the name may have initially referred to a person who resided in a particularly picturesque or scenic location, perhaps near a beautiful meadow or glade.
One of the earliest recorded instances of the SCHONLAU name appears in a 14th-century land registry from the region of Saxony, where a farmer named Hans SCHONLAU was listed as a landholder. This suggests that the name had already established itself as a surname by that time.
In the 16th century, a notable figure named Heinrich SCHONLAU (1506-1567) gained recognition as a Lutheran theologian and reformer in the city of Nuremberg. His writings and sermons played a role in the spread of Protestantism in the region.
During the 17th century, the SCHONLAU name appears in records from various parts of Germany, including the regions of Bavaria and Hesse. One individual of note was Johannes SCHONLAU (1618-1679), a merchant and civic leader in the town of Erfurt.
In the 18th century, the SCHONLAU name gained further prominence with the birth of Johann Lukas SCHONLAU (1786-1864), a pioneering German physician and professor of medicine. His contributions to the field of medical diagnosis and the understanding of diseases were significant, and he is considered one of the founders of modern clinical medicine.
Another notable figure bearing the SCHONLAU surname was the 19th-century poet and writer Karl SCHONLAU (1821-1899), who gained recognition for his lyrical poetry and contributions to German literature.
As the SCHONLAU name spread across German-speaking regions, variations in spelling and pronunciation emerged, including SCHÖNLAU, SCHÖNLOH, and SCHONLOH, among others. However, the core meaning and derivation from the Old German words for "beautiful" and "meadow" or "glade" remained consistent throughout its history.
Demographics
Among Census respondents with the surname Schonlau, the largest self-reported group is White at 99.2%. The next largest groups are Two or More Races (0.8%).
The bar chart below shows how Schonlau 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 Schonlau 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.
