Origin
Meaning and origin of Kallaus
The surname KALLAUS has its origins in Germany, where it first emerged in the 16th century. It is believed to be derived from the German word "kalle," which was a nickname for someone with a bald head or tonsured monk. The name may also have connections to the Old German word "calo," meaning "bald."
KALLAUS is thought to have originated in the region of Bavaria, where some of the earliest recorded instances of the name can be found in parish records and local chronicles. One of the earliest known bearers of the name was Hans Kallaus, a farmer from the village of Oberwössen, who lived in the late 1500s.
In the 17th century, the name appears in various historical documents from the region, including tax records and land registers. One notable example is Johann Kallaus, a landowner from the town of Straubing, who was mentioned in a deed dated 1642.
As the name spread beyond Bavaria, it underwent some variations in spelling, such as Kallaus, Kallauß, and Kallausch. These variations were likely due to regional dialects and the individual preferences of scribes who transcribed the name.
In the 18th century, the KALLAUS name gained further prominence with the birth of Johann Michael Kallaus (1718-1792), a Bavarian sculptor and woodcarver known for his intricate religious works. His son, Franz Xaver Kallaus (1760-1824), also became a renowned sculptor and carried on the family tradition.
Another notable figure was Maria Kallaus (1786-1856), a Bavarian folk artist and painter who gained recognition for her vibrant depictions of rural life and religious scenes.
In the 19th century, the name continued to be found in various parts of Germany, as well as in regions with German immigrant communities, such as parts of Austria and Switzerland. One prominent individual was Wilhelm Kallaus (1835-1912), a German-born engineer who made significant contributions to the development of early steam engines and locomotives.
As the 20th century approached, the KALLAUS name had become well-established across Germany and beyond, with bearers of the name making their mark in various fields, from academia and literature to business and politics.

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