Origin
The surname Walczewski originates from Poland and can be traced back to the 16th century. It is derived from the Polish word "walczyć," which means "to fight" or "to struggle." The name likely originated as a descriptive surname given to someone who was a skilled warrior or had a reputation for being a fighter.
One of the earliest recorded instances of the Walczewski name can be found in the Akta Grodzkie Krakowskie (Cracow Court Records) from the late 16th century. These records mention a man named Jan Walczewski, who was involved in a legal dispute over land ownership.
In the 17th century, the Walczewski name appears in various church records and parish registers across central and southern Poland. For example, a man named Tomasz Walczewski was born in the village of Działoszyce in 1642, and his son, Marcin Walczewski, was baptized in the same village in 1678.
During the Polish-Lithuanian Commonwealth era (16th-18th centuries), several notable individuals bore the Walczewski surname. One such person was Jakub Walczewski (1598-1666), a Polish nobleman and military commander who fought in the Smolensk War against Russia.
Another prominent figure was Stanisław Walczewski (1769-1840), a Polish general and politician who served in the Polish Army during the Napoleonic Wars. He later became a member of the Sejm (Polish parliament) and was a vocal supporter of Polish independence.
In the 19th century, the Walczewski name was found among Polish immigrants to the United States and other countries. One notable example is Jan Walczewski (1846-1912), a Polish-American civil engineer who worked on various railroad and bridge construction projects in the United States.
Other notable individuals with the Walczewski surname include Józef Walczewski (1710-1776), a Polish painter and etcher who worked in the Baroque and Rococo styles, and Tadeusz Walczewski (1879-1939), a Polish mathematician and academic who made significant contributions to the field of differential equations.
Demographics
Among Census respondents with the surname Walczewski, the largest self-reported group is White at 94.2%. The next largest groups are Two or More Races (3.3%) and Hispanic (0.8%).
The bar chart below shows how Walczewski 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 Walczewski 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.
