Origin
Meaning and origin of Galaszewski
The surname Galaszewski originates from Poland, tracing its roots back to the early 16th century. It is believed to have derived from the Polish word "galaz," meaning "branch," potentially referring to a person living near a prominent tree or forested area.
One of the earliest recorded instances of the name Galaszewski can be found in the parish records of the town of Sochaczew, located in central Poland, dating back to the late 1500s. It is also mentioned in various historical documents from the surrounding regions of Mazovia and Greater Poland.
During the 17th and 18th centuries, the Galaszewski name appears in several chronicles and manuscripts documenting the lives of notable individuals from the Polish nobility. For example, Jan Galaszewski (1620-1688) was a respected military commander who fought in the Polish-Swedish wars, and his exploits were recorded in the writings of contemporary historians.
Another prominent figure bearing this surname was Marcin Galaszewski (1765-1831), a renowned painter and portraitist who studied under the tutelage of the famous artist Jacques-Louis David in Paris. His works can be found in several esteemed art collections throughout Europe.
In the 19th century, the Galaszewski name was associated with several prominent intellectuals and scholars. Stanislaw Galaszewski (1822-1897) was a respected linguist and philologist who made significant contributions to the study of Slavic languages and folklore.
Another notable individual was Karolina Galaszewska (1888-1945), a pioneering educator and advocate for women's rights in Poland. She established several schools and educational institutions, and her efforts were instrumental in promoting female education during a time when it was not widely accepted.
The Galaszewski surname also has ties to various place names in Poland, such as the village of Galaszewo, located in the Masovian Voivodeship, which likely derived its name from the same linguistic root as the surname.
Throughout history, the Galaszewski name has been spelled in various ways, including Galaszowski, Galaszewicz, and Galaszeski, reflecting regional variations and linguistic evolutions over time.

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