Origin
Meaning and origin of Mazany
The surname Mazany originated in Poland, with the earliest recorded instances dating back to the 13th century. It is believed to have derived from the Polish word "mazać," which means "to smear" or "to anoint." This suggests that the name may have originally referred to someone who worked with oils, greases, or paints.
During the Middle Ages, the Mazany surname was primarily found in the regions of Krakow and Silesia, where many of the earliest bearers were artisans or craftsmen. Some historians have also linked the name to the Mazovian region of Poland, where it may have been used to identify individuals from that area.
One of the earliest documented mentions of the Mazany name can be found in the Liber Beneficiorum, a 14th-century record of benefices and properties in the Krakow diocese. The name appears several times in this manuscript, indicating its presence in the region during that period.
In the 16th century, a notable figure bearing the Mazany surname was Jan Mazany, a Polish painter and illustrator who was active in the city of Krakow. His works can still be seen in some of the city's churches and museums.
Another prominent individual with this surname was Stanisław Mazany, a Polish scholar and philosopher who lived in the 17th century. He was a professor at the Jagiellonian University in Krakow and wrote several influential treatises on logic and metaphysics.
During the 19th century, the Mazany name gained recognition through the works of Józef Mazany, a Polish poet and playwright. He was born in 1820 and is best known for his romantic and patriotic verses, which were popular during the Polish national revival movement.
In more recent history, Tadeusz Mazany was a Polish resistance fighter during World War II. He was actively involved in the Warsaw Uprising against the Nazi occupation and was awarded several medals for his bravery and service.
Throughout its history, the Mazany surname has also been associated with various place names in Poland, such as the village of Mazanów and the town of Mazańcowice. These locations likely derived their names from individuals bearing the Mazany surname who lived or owned property in those areas.

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