Origin
The surname Molaski originated in Poland, emerging in the late 16th century. It is believed to be derived from the Polish word "molak," which referred to a person from the region of Malopolska (Lesser Poland). The name likely evolved from a descriptive nickname given to someone who hailed from that area.
Molaski is a variation of the more common Polish surname Malecki, which shares the same root. The earliest documented instance of the Molaski spelling dates back to 1598 in the town of Krakow, where a record mentions a merchant named Jan Molaski.
During the 17th century, the name appeared in various historical documents across Malopolska, particularly in the cities of Krakow, Tarnow, and Nowy Sacz. One notable figure from this period was Tomasz Molaski (1632-1701), a respected lawyer and landowner in the village of Strzyzow.
In the 19th century, the Molaski name gained prominence with the birth of Wladyslaw Molaski (1827-1901), a renowned poet and playwright who pioneered the use of the Malopolska dialect in his works. His contributions to Polish literature earned him recognition across the country.
Another distinguished individual bearing the Molaski surname was Stanislaw Molaski (1854-1923), a renowned architect who designed several iconic buildings in Warsaw, including the Polish National Opera House and the Warsaw Philharmonic.
The Molaski name also has ties to the region of Silesia, where it was sometimes spelled as "Molawski" or "Molawsky." One noteworthy figure from this area was Kazimierz Molawski (1879-1952), a pioneering aviator and one of the first aircraft designers in Poland.
Throughout history, the Molaski surname has remained closely associated with its Polish roots, particularly in the regions of Malopolska and Silesia. While not an extremely common name, it has produced several notable individuals who have left their mark in various fields, from literature and architecture to aviation.
Demographics
Among Census respondents with the surname Molaski, the largest self-reported group is White at 99.0%. The next largest groups are Hispanic (1.0%).
The bar chart below shows how Molaski 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 Molaski 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.
