Origin
Meaning and origin of Dzierzynski
The surname Dzierzynski is of Polish origin, tracing its roots back to the late Middle Ages. It is believed to have originated from the village of Dzierzyn, located in the historical region of Greater Poland. This toponym is derived from the Old Polish word "dzierzyc," meaning "to possess" or "to hold," suggesting that the name may have initially referred to landowners or proprietors in the area.
One of the earliest recorded instances of the Dzierzynski name can be found in a 15th-century document from the town of Poznan, where a certain Jakub Dzierzynski was mentioned as a local landowner. This document serves as evidence that the name was already well-established in the region during that time period.
In the 16th century, the Dzierzynski family gained prominence in the Polish-Lithuanian Commonwealth. Notable members included Jan Dzierzynski, a military commander who served under King Sigismund III Vasa during the Polish-Swedish War (1626-1629), and Maciej Dzierzynski, a renowned scholar and rector of the Jagiellonian University in Krakow (1567-1572).
The 17th century saw the rise of Feliks Dzierzynski (1598-1662), a prominent Catholic bishop and diplomat who played a crucial role in the negotiations that led to the Treaty of Hadiach between the Polish-Lithuanian Commonwealth and the Cossack Hetmanate.
In the 19th century, the name gained international recognition through the figure of Feliks Dzierzynski (1877-1926), a Polish-Belarusian revolutionary and one of the founders of the Cheka, the first Soviet secret police force. He is widely regarded as a crucial figure in the establishment of the Soviet Union's security apparatus.
Another notable individual with the Dzierzynski surname was Ignacy Dzierzynski (1801-1870), a Polish historian and librarian who made significant contributions to the preservation and study of historical documents and manuscripts related to Polish history and culture.
Throughout its long history, the Dzierzynski name has been associated with various influential figures in fields such as politics, military, academia, and religion, reflecting the diverse roles and contributions of those who bore this surname across different eras and 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 Dzierzynski surname at the time of the 2020 Census, not any inherent property of the name itself.
