Origin
Meaning and origin of Dubisar
The surname DUBISAR is believed to have its origins in the Czech Republic, dating back to the 16th century. It is thought to have derived from the Czech words "dub" meaning oak and "sar" meaning ruler or leader, possibly referring to someone who lived near an oak forest or had authority over an oak-covered region.
One of the earliest recorded instances of the name appears in a land registry document from the town of Litomerice in 1587, where a farmer named Jan DUBISAR is listed as owning a parcel of land near the banks of the Elbe River. The name is also found in various church records from the same region during the late 1500s and early 1600s.
In the 17th century, the name DUBISAR seems to have spread to other parts of what is now the Czech Republic, with records showing individuals bearing the name in cities like Prague and Brno. One notable figure from this time was Karel DUBISAR, a wealthy merchant born in 1642 who was known for his philanthropic efforts in supporting local schools and churches.
As the DUBISAR family grew and expanded throughout the centuries, some members adopted slightly different spellings of the name, such as DUBISSAR or DUBISCHAR, likely due to regional variations in pronunciation and record-keeping practices.
Other notable individuals with the DUBISAR surname include:
1. Josef DUBISAR (1794-1873), a Czech composer and organist who composed numerous works for the church and is considered a pioneer of Czech sacred music.
2. Anna DUBISAR (1856-1932), a Czech writer and educator who published several novels and short stories aimed at promoting education and literacy among women.
3. Karel DUBISAR (1882-1957), a Czech architect and urban planner who designed several notable buildings in Prague and helped shape the city's modern urban landscape.
4. Jan DUBISAR (1912-1989), a Czech physicist and inventor who made significant contributions to the development of radar technology during World War II.
5. Eva DUBISAR (born 1948), a Czech actress and director who has appeared in numerous films and television productions both in her home country and abroad.
While the DUBISAR name may have originated in a specific region of the Czech Republic, it has since spread to other parts of the world, carried by various waves of emigration and cultural exchange.

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.

Keep in mind that these are self-reported numbers.

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
