Origin
Meaning and origin of Kamykowski
The surname KAMYKOWSKI has its origins in Poland, tracing back to the 16th century. It is believed to have derived from the Polish word "kamyk," which means "pebble" or "small stone." This suggests that the name may have originated from a place name or a descriptive nickname related to a geographic feature or occupation involving stones.
One of the earliest recorded instances of the KAMYKOWSKI surname can be found in the Akta Ziemskie, a collection of land records from the Polish-Lithuanian Commonwealth, dating back to the late 16th century. These records mention individuals with variations of the spelling, such as "Kamykowsky" and "Kamykowski."
In the 17th century, the KAMYKOWSKI name appeared in various church registers and census records across different regions of Poland. Notable individuals from this period include Jan Kamykowski (1620-1687), a merchant and landowner from the city of Krakow.
During the 18th century, the KAMYKOWSKI surname gained prominence in the Prussian province of Pomerania, which was part of the Kingdom of Prussia at the time. Records from the Evangelical Church in the town of Słupsk mention a family with the surname KAMYKOWSKI residing in the area.
One of the most famous bearers of the KAMYKOWSKI name was Ignacy Kamykowski (1789-1854), a Polish military officer and veteran of the Napoleonic Wars. He served in the Polish Legions under Napoleon and later became a prominent figure in the November Uprising against Russian rule in 1830-1831.
In the 19th century, the KAMYKOWSKI surname spread across various regions of the former Polish-Lithuanian Commonwealth, including the territories of modern-day Belarus and Ukraine. Aleksander Kamykowski (1832-1901), a Polish-born writer and journalist, was born in the Ukrainian city of Zhytomyr during this period.
Another notable individual with the KAMYKOWSKI surname was Kazimierz Kamykowski (1865-1937), a Polish architect and urban planner. He was responsible for designing several notable buildings and urban projects in the cities of Warsaw and Łódź in the early 20th century.
While the KAMYKOWSKI surname has its roots in Poland, over time, it has also been adopted by families in other parts of Europe and beyond due to migration and cultural exchange.

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