Origin
Meaning and origin of Kozick
The surname Kozick has its origins in Poland, traced back to the 16th century. It is believed to be derived from the Polish word "kozik," which means a small knife or dagger. The name likely originated as a descriptive surname, referring to an occupation or trade involving the use of such a tool.
In the early records of the Polish-Lithuanian Commonwealth, the name appears with various spellings, such as Kozicki, Koziczek, and Koziczyk. These variations reflect the phonetic adaptations and regional influences on the surname over time.
One of the earliest documented references to the name Kozick can be found in the parish records of the village of Koziczyn, located in the present-day Świętokrzyskie Voivodeship, Poland. The name appears in a baptismal record from 1612, indicating the presence of the Kozick family in this region during that period.
During the 17th century, the Kozick surname gained prominence in the area around the city of Kraków, where several members of the family were recorded as respected artisans and tradesmen. Notably, Jan Kozick (1645-1712) was a renowned blacksmith and knife-maker, renowned for his exquisite craftsmanship.
In the 18th century, the Kozick name spread further across Poland, with notable individuals including Mikołaj Kozick (1728-1804), a prominent landowner and local magistrate in the Lublin region, and Katarzyna Kozick (1765-1832), a renowned herbalist and midwife in the village of Koziczki.
As the Polish diaspora dispersed throughout Europe and beyond, the Kozick surname traveled with them. In the 19th century, Franciszek Kozick (1812-1887), a Polish immigrant to the United States, established a successful blacksmithing business in Chicago, contributing to the local Polish community.
Another notable figure was Aleksander Kozick (1860-1932), a Polish-born engineer who played a significant role in the construction of the Trans-Siberian Railway in Russia, a monumental feat of engineering at the time.
Over the centuries, the Kozick surname has maintained its presence in various parts of Poland, as well as among Polish communities worldwide, carrying with it the rich heritage and traditions associated with its origins.

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.
