Origin
Meaning and origin of Kasitz
The surname Kasitz is believed to have originated in the region of Silesia, which is now part of modern-day Poland and the Czech Republic. The name can be traced back to the late 15th century and is thought to be derived from the Old Slavic word "kasić," which means "to cough" or "to gasp."
One of the earliest known references to the name Kasitz can be found in the Silesian Duchy records from the early 16th century, where it is mentioned as a surname in the town of Jawor. Some historians believe that the name may have been originally used as a nickname for someone who had a persistent cough or respiratory illness.
The first recorded Kasitz was Jan Kasitz, who was born in the village of Strzegom in Silesia around 1520. He was a farmer and landowner, and his family is mentioned in several local records from that time period.
In the 17th century, the name spread to other parts of Europe as Silesian families migrated to different regions. There are records of a Michael Kasitz, who was a merchant in the city of Leipzig, Germany in the late 1600s.
One notable figure with the surname Kasitz was Friedrich Kasitz, a German military officer who served in the Prussian Army during the Napoleonic Wars. He was born in Breslau (now Wrocław, Poland) in 1778 and fought in several major battles, including the Battle of Jena-Auerstedt in 1806.
Another prominent individual was Maria Kasitz, a Polish artist and painter who lived in the 19th century. She was born in Cracow in 1825 and is known for her portraits and landscapes depicting scenes from rural Poland.
In the 20th century, there was a Czech writer named Karel Kasitz, who was born in Prague in 1918. He wrote several novels and short stories, and was known for his works exploring themes of identity and social issues in post-war Czechoslovakia.
Other notable individuals with the surname Kasitz include Hans Kasitz, a German architect from the late 19th century who designed several notable buildings in Berlin, and Anna Kasitz, a Polish-American educator and activist who fought for women's rights in the early 20th century.

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