Origin
Meaning and origin of Kozub
The surname KOZUB is of Polish origin, tracing its roots back to the 16th century. It is believed to have originated from the word "kozub," which translates to "wooden stick" or "club" in Polish. This suggests that the name may have initially referred to someone who worked with wood or used a wooden tool in their profession.
One of the earliest recorded instances of the KOZUB surname can be found in the historical records of the city of Krakow, dating back to the late 16th century. These records mention a man named Jan KOZUB, who was a carpenter by trade, supporting the theory that the name was related to woodworking occupations.
In the 17th century, the KOZUB name appeared in various Polish parish records, particularly in the regions of Małopolska and Silesia. During this time, the name also had variations in spelling, such as KOZUBE, KOZUBY, and KOZUBEK, which further emphasizes its Polish linguistic roots.
Historically, the surname KOZUB has been associated with several notable individuals. One such person was Mikołaj KOZUB, a Polish nobleman and landowner who lived in the late 17th century. He was a prominent figure in the region of Podkarpacie and was known for his involvement in local politics and administrative affairs.
Another remarkable bearer of the KOZUB surname was Józef KOZUB, a Polish artist and painter who lived in the 19th century. Born in 1807 in the village of Olszowce, he gained recognition for his landscape paintings and portraits, which captured the beauty of rural Poland and its people.
In the 20th century, Stanisław KOZUB, a Polish military officer and resistance fighter during World War II, made a significant impact. Born in 1908, he played a crucial role in the Polish Underground State and was awarded the Cross of Valour for his bravery and dedication to the cause of Polish independence.
Andrzej KOZUB, born in 1939, was a prominent Polish lawyer and judge who served on the Constitutional Tribunal of Poland from 1994 to 2003. His contributions to the interpretation and application of Polish constitutional law were highly regarded.
Another notable figure was Wiesław KOZUB, a Polish football player who represented the national team in the 1970s and 1980s. Born in 1954, he played as a midfielder and was part of the Polish squad that participated in the 1978 FIFA World Cup.

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