Origin
The surname Kleinwachter originated in Germany, with its earliest recorded instances dating back to the 16th century. The name is derived from the German words "klein" meaning "small" and "wachter" meaning "watchman" or "guard." It likely referred to a person who served as a night watchman or guard, perhaps in a small village or town.
The name Kleinwachter first appeared in historical records in the region of Bavaria, particularly in the areas around the cities of Munich and Nuremberg. It was also found in other parts of southern Germany, such as the Black Forest region and the areas bordering Switzerland and Austria.
One of the earliest recorded individuals with the name Kleinwachter was Hans Kleinwachter, a blacksmith from the town of Rothenburg ob der Tauber in Bavaria, who lived in the late 16th century. Another notable early bearer of the name was Johann Kleinwachter, a Protestant theologian and scholar who was born in Nuremberg in 1633 and died in 1688.
In the 18th century, the name Kleinwachter appeared in various church and civil records throughout Germany. For example, Johann Friedrich Kleinwachter, a composer and organist, was born in Meissen, Saxony, in 1736 and died in 1820.
The 19th century saw several notable individuals with the surname Kleinwachter. One was Friedrich Kleinwachter, a German jurist and legal scholar who was born in Königsberg (now Kaliningrad, Russia) in 1838 and died in 1927. Another was Theodor Kleinwachter, a German actor and theatre director who lived from 1840 to 1904.
Over time, the name Kleinwachter spread beyond Germany to other parts of Europe and eventually to other continents through emigration. For instance, Franz Kleinwachter was an Austrian-born architect who lived from 1838 to 1921 and worked primarily in the United States, designing several notable buildings in New York City.
While the name Kleinwachter has its roots in medieval Germany, it has since become a surname found in various parts of the world, carried by individuals with diverse backgrounds and professions, all tracing their lineage back to the small watchmen and guards of bygone eras.
Demographics
Among Census respondents with the surname Kleinwachter, the largest self-reported group is White at 93.8%. The next largest groups are Two or More Races (6.3%).
The bar chart below shows how Kleinwachter 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 Kleinwachter surname at the time of the 2020 Census, not any inherent property of the name itself.
