Origin
Meaning and origin of Klusendorf
The surname Klusendorf is of German origin, originating in the 14th century. It is derived from the Old German words "kluse" meaning "solitary place" or "hermitage" and "dorf" meaning "village". This suggests the name originated from a small settlement near a remote hermitage or monastery.
One of the earliest recorded instances of the name dates back to 1384 in the town of Rothenburg ob der Tauber, where a certain Hans Klusendorf was listed as a landowner. The name also appears in records from nearby villages around this time, with variations like Clusendorff and Klusendorffer.
In the 15th century, the Klusendorf name spread further across southern Germany, particularly in Bavaria and Franconia. Notable early bearers include Johann Klusendorf (1422-1499), a monk at the Benedictine abbey in Bamberg, and Michael Klusendorfer (1456-1522), a wealthy merchant from Nuremberg.
By the 16th century, the name had also taken root in parts of Austria and Switzerland. The Klusendorf family coat of arms, depicting a hermit standing before a church, dates back to this era and reflects the name's monastic origins.
Other notable Klusendorfs include Anna Klusendorf (1632-1703), a pioneering female botanist from Salzburg; Christoph Klusendorf (1711-1789), a master glassblower in Bavaria; and Karl Klusendorf (1845-1923), a German architect who designed several churches and public buildings in Munich.
As the centuries passed, spelling variations multiplied, with Klusendorfer, Klusensdorf, and Klusendorffer all appearing in historical records across German-speaking lands. Yet the name's essential meaning - that of a village near a hermitage - remained intact through its long history.

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 Klusendorf surname at the time of the 2020 Census, not any inherent property of the name itself.
