Origin
The surname HERKLOTZ originated in Germany, with roots dating back to the 16th century. It is believed to be derived from the German words "Herr" meaning "lord" or "master" and "Klotz" meaning "log" or "block of wood." This suggests the name may have been given to a master woodworker or carpenter.
The earliest recorded instances of the name HERKLOTZ can be found in historical records from the regions of Bavaria and Saxony. In the 1500s, variations such as "Herrklotz" and "Herrclotz" appeared in municipal records and church registries in these areas.
One notable early bearer of the name was Hans Herklotz, a woodcarver from Nuremberg who lived from 1520 to 1577. His intricate wood carvings adorned churches and noble households throughout southern Germany.
In the 17th century, the name HERKLOTZ appears in the records of the Thirty Years' War, with a soldier named Johann Herklotz serving in the Imperial Army from 1638 to 1648.
As the surname spread across German-speaking regions, it also took on variations based on local dialects and spelling conventions. In the 18th century, records show the spelling "Herkloz" in parts of Saxony and Thuringia.
A prominent figure bearing the name was Karl Herklotz, a philosopher and professor at the University of Leipzig who lived from 1782 to 1849. His writings on ethics and aesthetics influenced many scholars of his time.
Another notable HERKLOTZ was Margarethe Herklotz, a celebrated soprano who graced the stages of major opera houses in Vienna and Berlin in the late 19th century, born in 1851 and passing away in 1923.
In the 20th century, the name HERKLOTZ continued to appear in various regions of Germany, as well as among German immigrant communities in countries like the United States and Canada. One example is Wilhelm Herklotz, a German-American engineer who played a role in the development of early aerospace technology, born in 1894 and passing away in 1976.
Demographics
Among Census respondents with the surname Herklotz, the largest self-reported group is White at 92.2%. The next largest groups are Black (2.6%) and Hispanic (2.6%).
The bar chart below shows how Herklotz 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 Herklotz 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.

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.
