Origin
The surname HERTAUS is believed to have originated in Germany, with the earliest known records dating back to the 16th century. It is thought to be derived from the Old German words "herz" meaning heart and "haus" meaning house, potentially indicating a connection to an inn or tavern.
One of the earliest recorded instances of the name can be found in the town of Nuremberg, where a certain Hans Hertaus was listed as a local merchant in 1557. Another early reference comes from the city of Augsburg, where a family by the name of Hertaus was involved in the textile trade during the late 1500s.
By the 17th century, the name had spread to other regions of Germany, as well as neighboring countries like Austria and Switzerland. In 1632, a Johann Hertaus was documented as a landowner in the village of Oberammergau, located in the Bavarian Alps.
The name also appears in historical records related to the Protestant Reformation, with a pastor named Martin Hertaus serving in the town of Wittenberg, where Martin Luther famously initiated the movement in 1517.
As the centuries progressed, the Hertaus name continued to be found across various parts of Europe. Notable individuals bearing this surname include Konrad Hertaus (1675-1745), a respected clockmaker from the Black Forest region of Germany, and Katharina Hertaus (1789-1862), a prominent figure in the Austrian women's rights movement.
Other examples of historical figures with the Hertaus surname include Johann Hertaus (1817-1892), a German composer and organist, and Maximilian Hertaus (1859-1924), an Austrian architect who designed several notable buildings in Vienna.
While the spelling has remained relatively consistent over time, there are some instances of variations such as Herthaus or Herthauss appearing in older documents, likely due to regional differences in pronunciation and record-keeping practices.
Demographics
Among Census respondents with the surname Hertaus, the largest self-reported group is White at 97.1%. The next largest groups are Hispanic (1.9%) and Asian/Pacific Islander (1.0%).
The bar chart below shows how Hertaus 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 Hertaus 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 Hertaus (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.
