Origin
Meaning and origin of Ramotowski
The surname Ramotowski is of Polish origin, derived from the village of Ramoty in the Łódź region of central Poland. The name likely emerged in the late Middle Ages, around the 14th or 15th century, when it became common for people to adopt hereditary surnames derived from the places they lived.
Ramoty was first mentioned in historical records in 1391, with the name referring to a small settlement or hamlet. The name itself is thought to come from the Old Polish word "rama", meaning a frame or border, possibly referring to the layout or boundaries of the village.
One of the earliest recorded instances of the Ramotowski surname dates back to the 16th century, when a certain Jan Ramotowski was mentioned in a parish record from the town of Łowicz in 1564. Another early reference is to a Maciej Ramotowski, who served as a soldier in the Polish-Lithuanian Commonwealth in the late 17th century.
In the 18th century, the Ramotowski name appeared in various Polish nobility records, suggesting that some members of the family had achieved noble status. For example, a Franciszek Ramotowski was listed as a landowner in the Sieradz region in 1782.
A notable figure with this surname was Józef Ramotowski (1838-1913), a Polish painter and art teacher who specialized in portraiture and historical scenes. He studied in Warsaw and Rome, and his works can be found in several Polish museums and galleries.
Another person of note was Maria Ramotowska (1888-1979), a Polish mathematician and academic. She was one of the first women in Poland to receive a doctorate in mathematics and went on to have a distinguished career as a professor at the University of Warsaw.
In the 20th century, Henryk Ramotowski (1918-1993) was a prominent Polish lawyer and judge who served as the president of the Supreme Court of Poland from 1983 to 1990, during a tumultuous period in the country's history.
While the Ramotowski name is primarily found in Poland, it has also spread to other parts of the world through emigration, particularly to the United States and Canada in the late 19th and early 20th centuries.
Demographics
Ancestry and ethnicity for Ramotowski

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