Origin
Meaning and origin of Kaduk
The surname Kaduk has its origins in the Slavic regions of Eastern Europe, particularly in present-day Poland and Ukraine. It likely emerged sometime during the Middle Ages, though the precise timeline is uncertain. One theory suggests that the name is derived from the Slavic word "kaduk," which means "small piece" or "fragment," potentially indicating an ancestral connection to a craftsman or artisan.
The earliest known records of the Kaduk surname date back to the 15th century in the region of Galicia, which was then part of the Kingdom of Poland. An entry in the town records of Krakow from 1472 mentions a "Jan Kaduk," who was a merchant and landowner. This document provides one of the earliest written references to the surname.
In the 16th century, the Kaduk name appears in various legal documents and land registries across the Polish-Lithuanian Commonwealth. Notable individuals from this era include Stanislaw Kaduk (1524-1598), a prominent scholar and theologian who taught at the University of Krakow, and Katarzyna Kaduk (1548-1612), a noblewoman who inherited a substantial estate in the Lublin region.
As the Kaduk family spread across Eastern Europe, variations in spelling emerged, such as Kaduk, Kaduck, and Kaduczak. These variations were often influenced by regional dialects and linguistic conventions. In the 17th century, the Kaduk surname is found in historical records from the Grand Duchy of Lithuania, suggesting that members of the family had migrated eastward.
One notable figure from this period was Michal Kaduk (1632-1697), a military commander who fought in the Polish-Lithuanian wars against Sweden and Russia. His bravery and leadership earned him the title of "Colonel" and several land grants from the Polish king.
In the 18th century, the Kaduk name gained prominence in the region of Volhynia, which was then part of the Russian Empire. Franciszek Kaduk (1756-1823) was a respected landowner and philanthropist who established several schools and hospitals in the area.
As the 19th century dawned, the Kaduk family continued to play a role in the cultural and political life of Eastern Europe. Jakub Kaduk (1812-1878) was a renowned poet and writer who helped preserve and promote the Polish language and literature during a period of foreign domination.
Throughout its history, the Kaduk surname has been borne by individuals from various walks of life, including academics, military leaders, artists, and landowners. While its exact origins remain somewhat obscure, the name has endured as a testament to the rich cultural heritage of the Slavic regions.

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