Origin
Meaning and origin of Hausenfluck
The surname Hausenfluck is believed to have originated in the German region of Bavaria in the late 15th century. It is thought to be derived from the Old German words "hausen" meaning "to dwell" and "fluck" meaning "fluke" or "chance occurrence." This suggests the name may have originally referred to someone who lived in a dwelling or house that was acquired by chance or circumstance.
One of the earliest recorded instances of the Hausenfluck name appears in a land registry from the town of Rothenburg ob der Tauber in 1492, where a Johannes Hausenfluck is listed as a landowner. In 1517, a Matthias Hausenfluck is mentioned in the records of the nearby village of Schrozberg as having been fined for fighting in a local tavern.
By the 16th century, variations of the name had spread to other parts of southern Germany and neighboring regions. A Hans Haussenfluck is documented as a master baker in the city of Nuremberg in 1549. Around 1582, a Margaretha Haussenfluck is recorded as having married a Johann Schmitt in the town of Ellwangen.
One of the earliest notable individuals with the Hausenfluck name was Peter Hausenfluck (1523-1597), a Lutheran theologian and author from Rothenburg who wrote several treatises on Protestant doctrine. Another was Johann Hausenfluck (1564-1628), a professor of law at the University of Ingolstadt who published works on legal theory.
During the 17th century, the name appears in records from various towns and cities across southern Germany and parts of Austria. A Georg Hausenfluck (1612-1682) is listed as a master woodcarver in the city of Ulm. A Maria Hausenfluck (1638-1701) is recorded as having been a midwife in the town of Memmingen.
By the 18th century, the Hausenfluck name had also spread into parts of Switzerland, particularly the German-speaking cantons. One notable bearer was Johann Jakob Hausenfluck (1725-1789), a Swiss artist and engraver from Basel who produced many intricate etchings and woodcuts.
Throughout its history, the Hausenfluck surname has maintained a relatively low frequency, likely due to its specific regional origins. However, it continues to be found scattered across Germany, Austria, and parts of Switzerland to this day, a testament to its longevity and enduring legacy.

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