Origin
Meaning and origin of Kasler
The surname KASLER is of German origin, tracing its roots back to the 14th century. It is believed to have originated in the region of Bavaria, where it may have derived from the German word "Kassler," which refers to a type of smoked and cured pork loin.
During the Middle Ages, surnames were often derived from occupations, geographical locations, or personal characteristics. In the case of KASLER, it is possible that the name was initially associated with individuals involved in the production or trade of cured meats, particularly in the Bavarian region.
One of the earliest recorded instances of the KASLER surname can be found in a 15th-century manuscript from the city of Nuremberg, where a merchant named Johannes Kasler was mentioned. This document provides evidence that the name was already in use during that time period.
In the 16th century, the KASLER surname appeared in various records across German-speaking regions, including references to notable individuals such as Heinrich Kasler, a renowned clockmaker from Augsburg, who lived from 1522 to 1587.
As time progressed, the KASLER surname spread beyond its initial geographical origins. In the 17th century, a notable figure named Wilhelm Kasler (1633-1692) was a prominent theologian and philosopher from the city of Heidelberg.
During the 18th century, the KASLER surname gained further recognition with the birth of Johann Kasler (1745-1818), a celebrated composer and organist from the city of Dresden. His contributions to the musical landscape of the time were significant.
Another notable individual bearing the KASLER surname was Friedrich Kasler (1788-1856), a German author and poet who gained recognition for his literary works, particularly his collection of poems titled "Gedichte" published in 1823.
It is important to note that while these historical examples provide insight into the origins and early usage of the KASLER surname, the name has likely undergone various spelling variations and adaptations over time as it spread across different regions and cultures.

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