Wasilewski is a patronymic surname, meaning it originated as a way to identify someone as the son or descendant of a person named Wasilij or Vasil. The suffix "-ewski" is a common Polish patronymic ending, indicating the name's Polish roots.
One of the earliest recorded instances of the name Wasilewski can be found in the Księgi Metrykalne, or Parish Records, of the Polish-Lithuanian Commonwealth in the 16th century. These records document the births, marriages, and deaths of individuals with the surname Wasilewski in various towns and villages across the region.
In the 17th century, a notable figure bearing the name Wasilewski was Andrzej Wasilewski (1635-1711), a Polish nobleman and military commander who fought in the Polish-Ottoman Wars. He was renowned for his bravery and leadership in battles against the Ottoman Empire.

Lastly, Jerzy Wasilewski (1942-2022) was a Polish film director and screenwriter known for his critically acclaimed movies that tackled social and political issues in Poland during the communist era.

The bar chart below shows how Wasilewski 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 Wasilewski surname at the time of the 2020 Census, not any inherent property of the name itself.
