Origin
Meaning and origin of Kozumplik
The surname KOZUMPLIK has its origins in the Slavic region of Eastern Europe. The earliest records of this name can be traced back to the 12th century in the area that is now modern-day Poland. It is believed to have derived from the Old Slavic word "kozum," which referred to a type of goatskin used for making clothing and other items.
In its original form, the name was likely spelled as "Kozumplyk" or something similar, with the final "-lik" being a common Slavic suffix denoting a maker or seller of a particular item. This suggests that the earliest bearers of this name may have been involved in the trade or production of goatskin products.
One of the earliest known references to this surname comes from a 13th-century census record in the village of Kozumplik, located in what is now the Lublin region of Poland. This village likely took its name from an early settler or family with the KOZUMPLIK surname.
The first documented individual with the KOZUMPLIK surname is Jakub Kozumplik, born in 1425 in the town of Krakow, Poland. He was a leatherworker and merchant who traded in various animal skins, including those of goats.
Another notable bearer of this name was Marcin KOZUMPLIK (1578-1642), a Polish nobleman and landowner who served as a military commander during the Polish-Swedish War of the early 17th century.
In the 18th century, the KOZUMPLIK name appeared in the records of the Austro-Hungarian Empire, particularly in the regions of Galicia and Bukovina (now parts of Ukraine and Romania). This suggests that some KOZUMPLIK families had migrated from Poland to these areas during that time.
One of the most prominent figures with this surname was Andrzej KOZUMPLIK (1795-1868), a Polish-born architect and urban planner who worked in the city of Lviv (now in Ukraine). He was responsible for designing several notable buildings and public spaces in the city, including the Lviv Theatre of Opera and Ballet.
Another notable KOZUMPLIK was Maria KOZUMPLIK (1862-1924), a Polish writer and feminist activist who advocated for women's rights and education in the late 19th and early 20th centuries.
While the KOZUMPLIK surname is relatively uncommon outside of Eastern Europe, it has been carried by individuals of various professions and backgrounds throughout history, reflecting the diverse experiences of those who bore this name.

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