Origin
Meaning and origin of Kozup
The surname KOZUP is of Slavic origin, with its roots traced back to the regions of Eastern Europe, particularly Poland and Ukraine. The earliest known records of this surname date back to the 16th century, when it was commonly found in various Polish and Ukrainian villages.
The KOZUP name is believed to have derived from the Slavic word "koza," which means "goat" in English. This suggests that the name may have originated from an occupation or a nickname related to goat herding or trading in goat-related products. Alternatively, it could also be a toponymic surname, referring to a place name associated with goats.
One of the earliest known mentions of the KOZUP surname can be found in the Metryka Koronna, a collection of historical documents from the former Polish-Lithuanian Commonwealth, dating back to the 16th century. This record includes several references to individuals bearing the KOZUP surname, indicating their presence in various regions of Poland and Ukraine during that time period.
In the 17th century, the KOZUP name appeared in several parish records and land registers in the regions of Galicia (now part of western Ukraine) and Podolia (now part of Ukraine and Moldova). These records provide valuable insights into the lives and backgrounds of KOZUP families during that era.
One notable individual with the KOZUP surname was Jan KOZUP (1648-1721), a Polish landowner and nobleman who served as a councilor to the Polish king, John III Sobieski. Another prominent figure was Andrii KOZUP (1789-1862), a Ukrainian philosopher and educator who contributed significantly to the development of Ukrainian intellectual thought during the 19th century.
In the 18th and 19th centuries, the KOZUP surname continued to be present in various regions of Eastern Europe, with families bearing this name found in historical records from Poland, Ukraine, Belarus, and Russia. Notable individuals from this period include Maksym KOZUP (1756-1824), a Ukrainian Cossack leader who fought against Russian imperial forces, and Olena KOZUP (1814-1892), a renowned Ukrainian folk singer and storyteller.
Throughout its history, the KOZUP surname has been associated with several variations in spelling, such as Kozupa, Kozupp, and Kozupski, reflecting regional linguistic differences and variations in record-keeping practices. Despite these variations, the core meaning and origin of the name have remained consistent, reflecting its deep-rooted Slavic heritage.

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.
