Origin
Meaning and origin of Hasenfuss
The surname HASENFUSS has its origins in the German language, and can be traced back to the Middle Ages, specifically the 13th century. It is believed to have originated in the region of Bavaria, which was then part of the Holy Roman Empire.
The name HASENFUSS is a compound word, derived from the German words "Hase," meaning "hare," and "Fuss," meaning "foot." It is thought to have been initially used as a descriptive nickname, possibly referring to someone with swift feet or a light, agile gait, much like a hare.
Early records indicate that the name appeared in various manuscripts and documents from the 14th century onward, including municipal records and church registers in towns and villages across southern Germany. One of the earliest documented instances of the name can be found in the Heidelberg Manuscript, a collection of legal documents dating back to 1380, which mentions a certain "Hans Hasenfuss."
In the 15th century, the name HASENFUSS was also found in the town records of Augsburg, a prominent city in Bavaria. A notable figure from this time was Konrad Hasenfuss (1420-1491), a respected merchant and landowner in the region.
As the centuries passed, the HASENFUSS name spread to other parts of Germany, as well as neighboring countries like Austria and Switzerland. In the 16th century, a notable bearer of the name was Johann Hasenfuss (1541-1612), a Lutheran theologian and scholar from Saxony.
In the 17th century, the name HASENFUSS appeared in records from the town of Nuremberg, with the birth of Matthias Hasenfuss (1625-1698), a prominent clockmaker and inventor of his time.
Another noteworthy figure was Friedrich Hasenfuss (1788-1864), a German painter and engraver from the city of Dresden, who gained recognition for his landscapes and portraiture during the Romantic era.
As the name HASENFUSS continued to spread across Europe, it was sometimes adapted to local spellings and pronunciations. For example, in the Netherlands, it was sometimes rendered as "Hazenvoet," while in France, it became "Hazenfus" or "Hazenfuss."

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