Origin
The surname DEMBOSKY is believed to have originated in Eastern Europe, specifically in the region of modern-day Poland and Ukraine. Its origins can be traced back to the 15th or 16th century. The name is likely derived from the Slavic word "demb," which means "oak tree," and the suffix "-oski," indicating a possessive form. Therefore, the name DEMBOSKY could have initially referred to someone who lived near or owned an oak forest or grove.
One of the earliest documented references to this surname can be found in a Polish census record from the late 16th century, where it was spelled "Demboski." This variation in spelling was common during that time due to the lack of standardized spelling conventions. Other similar spellings included "Demboski," "Dembovsky," and "Dembowsky."
In the 17th century, the DEMBOSKY surname appears in several historical records from the region, suggesting that the family had established itself as landowners or minor nobility. One notable bearer of this name was Jan Dembosky (1625-1689), a Polish military officer who fought in the Polish-Swedish wars of the mid-17th century.
As the centuries passed, the DEMBOSKY surname spread across Eastern Europe, and some variations of the name emerged, such as "Dembski" and "Dembsky." In the 19th century, a prominent figure bearing this surname was Bronisław Dembski (1833-1914), a Polish mathematician and educator who made significant contributions to the field of number theory.
Another noteworthy individual was Michal Dembosky (1871-1949), a Ukrainian-born artist and painter who was part of the Impressionist movement in Eastern Europe. His works, which often depicted landscapes and rural scenes, are now housed in several museums across the region.
The DEMBOSKY surname also found its way to other parts of the world through immigration. One such example is Ivan Dembosky (1892-1967), a Russian-born author and journalist who emigrated to the United States in the early 20th century and wrote extensively about the experiences of immigrants in America.
Throughout its history, the DEMBOSKY surname has been carried by various individuals from different walks of life, including scholars, artists, military personnel, and writers. While the name's origins can be traced back to Eastern Europe, its bearers have left their mark across various regions and cultures over the centuries.
Demographics

The bar chart below shows how Dembosky 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 Dembosky 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.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
