Origin
Meaning and origin of Ausmus
The surname Ausmus is of German origin, tracing its roots back to the Middle Ages. It is believed to have emerged in the region of Bavaria, which was home to many German nobility and aristocratic families during that era.
One theory suggests that the name Ausmus is derived from the Old Germanic personal name "Audumarus," which is composed of the elements "aud" meaning "wealth" and "mari" meaning "famous." This name was later contracted and evolved into various forms, including Ausmus.
Another possibility is that Ausmus originated as a toponymic surname, referring to a specific place or location. In this case, it may have been derived from the name of a town or village where the earliest bearers of the name resided.
The earliest known record of the surname Ausmus dates back to the 14th century, when it appeared in various medieval German chronicles and manuscripts. One notable reference is found in the "Codex Diplomaticus Brandenburgensis," a collection of historical documents from the Margraviate of Brandenburg, where an individual named Johannes Ausmus is mentioned in the year 1372.
In the 15th century, the name Ausmus gained prominence with the birth of Johann Ausmus (1435-1501), a respected German scholar and theologian who served as a professor at the University of Ingolstadt. He was known for his contributions to the study of canon law and his writings on ecclesiastical reforms.
Another notable figure was Hans Ausmus (1541-1607), a German cartographer and engraver who created detailed maps of various regions in Europe. His work was highly regarded and helped shape the field of cartography during the Renaissance.
In the 17th century, the name Ausmus appeared in the records of the town of Neustadt an der Weinstraße, located in the Palatinate region of Germany. One prominent individual from this area was Johann Philipp Ausmus (1629-1698), a successful merchant and landowner who played an influential role in local affairs.
During the 18th century, the Ausmus family expanded their presence across Germany, with several members achieving recognition in various fields. One such individual was Friedrich Wilhelm Ausmus (1720-1789), a respected jurist and legal scholar who served as a judge in the city of Berlin.
In the 19th century, the name Ausmus continued to be found throughout Germany, with several individuals making notable contributions. Among them was Karl Ausmus (1822-1881), a renowned German architect who designed several prominent buildings in Berlin and other cities.

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.
