Origin
Meaning and origin of Topolosky
The surname Topolosky originates from Slavic roots, with its earliest known bearers hailing from the region of modern-day Poland and Ukraine during the medieval period. The name is believed to derive from the Slavic word "topol," meaning "poplar tree," suggesting that the Topolosky family may have resided near or worked with poplar trees.
One of the earliest recorded instances of the Topolosky surname can be traced back to the 15th century in the Ruthenian Voivodeship, a historical region spanning parts of present-day western Ukraine and southeastern Poland. In 1492, a document mentions a certain Andrei Topolosky, a landowner in the village of Khmeliv, near the city of Lviv.
During the 16th century, the Topolosky name gained prominence in the Polish-Lithuanian Commonwealth, with several notable bearers emerging. Jan Topolosky (1510-1578) was a respected scholar and theologian who taught at the University of Krakow. His contemporary, Mikołaj Topolosky (1525-1592), served as a military officer and participated in numerous campaigns against the Ottomans and the Crimean Khanate.
In the 17th century, the Topolosky name appears in historical records related to the Polish-Muscovite War of 1654-1667. Aleksander Topolosky (1620-1682) was a renowned cavalry officer who fought alongside King Jan Kazimierz and distinguished himself in several battles against the Russian forces.
The 18th century saw the rise of Franciszek Topolosky (1745-1819), a prominent Polish nobleman and landowner who played a significant role in the Kościuszko Uprising against the partitioning of Poland by Russia, Prussia, and Austria. His estate, located in the village of Topolosky (now known as Topolowka), became a stronghold for the Polish resistance movement.
As the Topolosky family spread across Eastern Europe, the name underwent various spelling variations, such as Topoloski, Topolowsky, and Topolovskyy. One notable bearer from this period was the Ukrainian writer and poet, Ivan Topolovskyy (1810-1876), whose works contributed to the revival of Ukrainian literature and culture.

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