Origin
Meaning and origin of Dembicki
The surname Dembicki is of Polish origin, originating in the 16th or 17th century. It is derived from the Polish word "dąb," meaning "oak," combined with the diminutive suffix "-icki." This suggests that the earliest bearers of this name may have lived near an oak forest or oak tree.
One of the earliest recorded instances of the Dembicki name can be found in the "Herbarz Polski" (Polish Armorial), a compilation of Polish noble families' coats of arms and histories, dating back to the 16th century. The Dembicki family is listed as a noble family from the Prussian region, which at the time was part of Poland.
In the late 18th century, a notable figure bearing the Dembicki name was Jan Dembicki (1738-1810), a Polish nobleman and politician who served as a member of the Polish Sejm (parliament) and supported the Polish Constitution of May 3, 1791, considered one of the first modern constitutions in Europe.
The 19th century saw the birth of Bronisław Dembicki (1858-1939), a Polish mathematician and academic who made significant contributions to the field of number theory. He served as a professor at the University of Lviv and the Jagiellonian University in Krakow.
Another prominent figure with the Dembicki surname was Stanisław Dembicki (1896-1976), a Polish actor and theater director who founded the Ateneum Theatre in Warsaw in 1928. He was renowned for his avant-garde productions and played a pivotal role in the development of modern Polish theater.
In the early 20th century, Józef Dembicki (1905-1978) was a Polish politician and diplomat who served as the ambassador of the Polish People's Republic to several countries, including the Soviet Union and Romania. He was also a member of the Polish United Workers' Party (PZPR) and held various governmental positions.
The Dembicki name can also be traced back to several villages and towns in Poland, such as Dębicki in the Małopolska region and Dębice in the Podkarpackie region, which may have been the original homelands of families bearing this surname.

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