Origin
The surname Guzewicz is of Polish origin, and its roots can be traced back to the medieval period in the region of modern-day Poland. The name is believed to have derived from the Polish word "guz," which means "knot" or "lump," suggesting a potential occupation or distinguishing physical characteristic associated with the original bearer.
One of the earliest recorded instances of the surname Guzewicz can be found in the 16th-century parish records of the village of Guzew, located in the Mazovian region of central Poland. This connection indicates that the name likely originated as a toponymic surname, referring to an individual's place of birth or residence.
In the 17th century, a notable figure bearing the Guzewicz surname was Jan Guzewicz, a prominent merchant and landowner in the city of Krakow. He played a significant role in the local trade and commerce, and his name is mentioned in several historical documents from that era.
Another notable individual was Katarzyna Guzewicz, a celebrated poet and writer who lived in the late 18th century. Her works, which explored themes of love, nature, and patriotism, gained widespread acclaim and contributed to the cultural renaissance of the Polish literary tradition.
During the 19th century, the Guzewicz family produced several respected academics and scholars. One such figure was Tomasz Guzewicz (1812-1887), a renowned linguist and professor at the University of Warsaw. His groundbreaking research on Slavic languages and their historical development earned him widespread recognition among his peers.
In the early 20th century, the Guzewicz surname gained further prominence with the life of Stanislaw Guzewicz (1895-1968), a celebrated artist and painter whose works captured the vibrant landscapes and cultural traditions of rural Poland. His paintings are now displayed in prestigious galleries and museums across the country.
Throughout its history, the Guzewicz surname has been associated with various professions and notable individuals, reflecting the rich cultural heritage and diverse contributions of those who bore this name. While the name originated in Poland, it has since spread globally, carried by descendants and immigrants who have left their mark on various communities worldwide.
Demographics
Among Census respondents with the surname Guzewicz, the largest self-reported group is White at 100.0%.
The bar chart below shows how Guzewicz 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 Guzewicz 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.
