Origin
The surname Krzoska is of Polish origin, dating back to the 15th century. It is believed to have originated in the region of Greater Poland, particularly in the areas around the cities of Poznań and Gniezno. The name Krzoska is derived from the Polish word "krzos," which means "spark" or "ember," suggesting a possible connection to an occupation or location related to fire or blacksmithing.
One of the earliest recorded instances of the surname Krzoska can be found in the Tarnów Land Records from the late 15th century, where a certain Jan Krzoska was mentioned as a landowner in the village of Brzesko. In the 16th century, the Krzoska family was documented as residing in the town of Kościan, which was part of the Poznań Voivodeship at the time.
During the 17th century, the name Krzoska appeared in various church records and municipal documents across the regions of Greater Poland and Kuyavia. Notably, in 1629, a Marcin Krzoska was recorded as a prominent merchant in the city of Bydgoszcz, which was then part of the Polish-Lithuanian Commonwealth.
In the 18th century, the Krzoska surname gained recognition through the achievements of Franciszek Krzoska (1710-1785), a renowned Polish architect and urban planner. He was responsible for the design and construction of several notable buildings in Warsaw, including the Krasiński Palace and the Church of the Holy Cross.
Another notable bearer of the Krzoska name was Józef Krzoska (1815-1888), a Polish writer and journalist who played a significant role in the development of Polish literature during the Romantic period. He is particularly remembered for his contributions to the literary magazine "Tygodnik Ilustrowany."
In the 20th century, Stanisław Krzoska (1901-1982) was a prominent Polish sculptor and painter known for his monumental works and murals. His sculptures can be found in various public spaces across Poland, including the Warsaw University of Technology and the National Museum in Poznań.
While the Krzoska surname is relatively uncommon outside of Poland, it has been carried by several individuals throughout history, reflecting its Polish roots and the diverse contributions of its bearers to various fields, including architecture, literature, and the arts.
Demographics
Among Census respondents with the surname Krzoska, the largest self-reported group is White at 100.0%.
The bar chart below shows how Krzoska bearers described their own race and ethnicity on the 2020 Census form. 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 Krzoska surname at the time of the 2020 Census, not any inherent property of the name itself.

No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
