Origin
The surname Hartzog is believed to have originated in Germany during the Middle Ages. It is thought to be derived from the Old German words "hart" meaning "hardy" or "brave" and "zog" meaning "leader" or "duke." Together, the name likely referred to a brave or hardy leader or military commander.
One of the earliest recorded instances of the name Hartzog appears in a manuscript from the 13th century, which mentions a nobleman named Heinrich Hartzog who fought in the Crusades. Another early reference is found in a 14th century text that details the exploits of a knight named Konrad Hartzog during the Hundred Years' War.
In the 16th century, the Hartzog surname began to appear in various regions of Germany, including Bavaria, Saxony, and the Rhineland. During this time, the name may have been associated with certain place names, such as Hartzhausen or Hartzheim, though the exact connections are unclear.
One notable individual with the Hartzog surname was Johann Hartzog (1570-1642), a German theologian and author who wrote extensively on religious topics. Another was Heinrich Hartzog (1632-1701), a German composer and organist who served at several churches in Saxony.
In the 18th century, the Hartzog name spread to other parts of Europe, with some families emigrating to the United States and other parts of the Americas. One early American bearer of the name was Johann Hartzog (1725-1798), a German immigrant who settled in Pennsylvania and fought in the American Revolutionary War.
Other notable individuals with the Hartzog surname include Friedrich Hartzog (1820-1891), a German industrialist and pioneer in the steel industry, and Wilhelm Hartzog (1876-1945), a German military officer who served in both World Wars.
Throughout its history, the Hartzog surname has maintained its associations with bravery, leadership, and military service, reflecting its origins as a name borne by hardy commanders and nobles in medieval Germany.
Demographics
Among Census respondents with the surname Hartzog, the largest self-reported group is White at 77.3%. The next largest groups are Black (15.6%) and Two or More Races (3.6%).
The bar chart below shows how Hartzog 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 Hartzog 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.
