Origin
Meaning and origin of Hemauer
The surname Hemauer is of German origin, emerging in the late medieval period around the 14th or 15th century. It is believed to have derived from the German words "heim," meaning home or homestead, and "auer," referring to a meadow or open field. This suggests the name may have initially referred to someone residing near or owning a homestead situated in a meadow or open area.
One of the earliest recorded instances of the Hemauer surname can be found in the town records of Augsburg, Germany, dating back to the early 16th century. The name also appears in various other historical documents from southern German regions, such as Bavaria and Baden-Württemberg, during the 16th and 17th centuries.
Notably, the Hemauer surname is associated with a prominent family of merchants and bankers from the city of Nuremberg in the 15th and 16th centuries. Hans Hemauer (c. 1450-1518) was a renowned merchant and patrician who served as a member of the city council and held influential positions within the city's government.
Another notable figure bearing the Hemauer name was Johann Baptist Hemauer (1743-1822), a German Catholic theologian and philosopher who taught at the University of Ingolstadt and later became a canon of the Regensburg Cathedral.
In the realm of literature, Johann Michael Hemauer (1773-1852) was a German poet and author who gained recognition for his works in the Swabian dialect. His poems and writings offered insights into the cultural and linguistic traditions of the Swabian region.
Moving into the 19th century, Karl Hemauer (1820-1899) was a German architect and engineer who made significant contributions to the field of bridge construction. He designed and oversaw the construction of several notable bridges across Germany, including the Wertach Bridge in Augsburg.
It is worth noting that while the Hemauer surname has its roots in southern Germany, it has since spread to other regions and countries due to migration and travel. However, the most comprehensive historical records and notable figures associated with this surname can be traced back to its German origins.

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