Origin
Meaning and origin of Ozarowski
The surname Ozarowski is of Polish origin, tracing its roots back to the early Middle Ages. It is believed to have originated from the small village of Ozarów, located in central Poland. The name is derived from the Polish word "ozar," which means "a person who clears land for cultivation."
In the 13th century, many Polish families adopted surnames based on their professions or places of origin. The Ozarowski name likely emerged during this period, indicating that the family's ancestors were involved in clearing and cultivating land in the area around Ozarów.
One of the earliest recorded mentions of the Ozarowski name can be found in the Księga Henrykowska (Book of Henryków), a historic document from the late 14th century. This manuscript lists several individuals bearing the surname, suggesting that the Ozarowski family had already established itself in the region by that time.
Throughout the centuries, the Ozarowski name has appeared in various historical records and documents across Poland. In the 16th century, Jan Ozarowski (1535-1605) was a prominent Polish nobleman and military commander who served under King Sigismund III Vasa during the Polish-Swedish War.
Another notable figure was Adam Ozarowski (1655-1720), a Polish mathematician and astronomer who made significant contributions to the study of celestial mechanics. His work on the motion of planets and comets was widely recognized in academic circles of the time.
In the 19th century, Stanisław Ozarowski (1813-1890) was a renowned Polish painter and art educator. His masterpieces, depicting scenes from Polish history and folklore, are prominently displayed in several museums across the country.
During the early 20th century, Maria Ozarowska (1892-1975) was a celebrated Polish actress who graced the stages of many prestigious theaters in Warsaw and Krakow. Her performances in classical plays by Shakespeare and Molière were highly acclaimed.
The Ozarowski surname has also been associated with various place names throughout Poland, such as Ozarów Mazowiecki, a town located near Warsaw, and Ozarów Śląski, a village in the Silesian region. These locations may have contributed to the spread and variations of the surname over time.
While the Ozarowski name has its roots in Poland, it has since spread to other parts of the world, carried by generations of Polish immigrants and their descendants. However, its origins remain deeply rooted in the Polish language and the historical traditions of the region.

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