Origin
Meaning and origin of Kasman
The surname KASMAN is believed to have originated in Germany, with records dating back to the 16th century. It is derived from the German word "Kasman," which means "treasurer" or "cashier." This suggests that the name may have been given to someone who worked in the financial or accounting field.
One of the earliest known references to the name KASMAN can be found in the records of the city of Nuremberg, where a merchant named Hans KASMAN is mentioned in a document from 1578. It is possible that this individual or his ancestors were involved in the city's thriving trade and banking industry.
In the 17th century, the name KASMAN appeared in various regions of Germany, including Bavaria and Saxony. During this time, the spelling of the name varied, with some records showing it as "Kasman," "Kasmann," or "Kassmann."
A notable figure bearing the KASMAN surname was Johann KASMAN, a Lutheran theologian and philosopher who lived from 1592 to 1647. He was a professor at the University of Leipzig and authored several works on theology and logic.
The KASMAN name also has roots in the Netherlands, where it is believed to have been introduced by German immigrants in the 17th and 18th centuries. One of the earliest recorded instances of the name in the Netherlands is found in the marriage records of Amsterdam in 1692, where a man named Pieter KASMAN is listed.
In the 19th century, the KASMAN surname spread to other parts of Europe and beyond. For example, a man named Wilhelm KASMAN, born in 1822 in Germany, is known to have emigrated to the United States in the mid-1800s and settled in Pennsylvania.
Another notable bearer of the KASMAN name was Gerhard KASMAN, a German-born botanist who lived from 1887 to 1957. He made significant contributions to the study of plant taxonomy and is particularly known for his work on the flora of South Africa.

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