Origin
The surname Ursenbach originates from the German-speaking region of Switzerland, dating back to the late 15th century. It is believed to be derived from the Old High German words "urso" (bear) and "bach" (stream), suggesting a connection to a place where bears frequented a particular stream or river.
One of the earliest recorded instances of this surname can be found in the village of Ursenbach, located in the Swiss canton of Bern. This village's name is mentioned in historical records as early as 1490, and it is likely that the surname Ursenbach emerged from this location.
During the 16th and 17th centuries, the Ursenbach family played a significant role in the local governance and cultural life of the region. Notable individuals from this period include Johann Ursenbach (1532-1599), a respected magistrate and landowner, and Anna Ursenbach (1572-1648), who is renowned for her contributions to the preservation of traditional Swiss folk songs and dances.
In the 18th century, the Ursenbach family expanded its influence beyond Switzerland. Johannes Ursenbach (1712-1781), a skilled watchmaker, emigrated to France and established a successful business in Paris, where his timepieces were highly sought after by the aristocracy.
As the 19th century dawned, the Ursenbach name gained prominence in the field of academia. Karl Ursenbach (1821-1896), a renowned linguist and scholar, authored several influential works on the history and evolution of the German language.
Another notable figure from this era was Emilie Ursenbach (1856-1932), a pioneering Swiss painter and illustrator whose works captured the beauty of the Alpine landscapes and the traditional way of life in rural Switzerland.
Throughout the 20th century, the Ursenbach surname continued to be associated with various fields, including politics, science, and the arts. Notable individuals include Hans Ursenbach (1901-1987), a respected politician and diplomat who served as the Swiss ambassador to several countries, and Erich Ursenbach (1925-2001), a renowned physicist whose research on quantum mechanics garnered international recognition.
While the name Ursenbach may have evolved over time, its roots remain firmly grounded in the Swiss Alps, where it originated as a locational surname centuries ago.
Demographics

The bar chart below shows how Ursenbach 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 Ursenbach surname at the time of the 2020 Census, not any inherent property of the name itself.
