Origin
Meaning and origin of Nesvacil
The surname Nesvacil has its origins in the Czech Republic, dating back to the 16th century. It is believed to have derived from the Czech word "nesvačit," which means "not to have a snack or meal." This suggests that the name may have initially referred to someone who skipped meals or fasted regularly, perhaps for religious or health reasons.
One of the earliest recorded instances of the Nesvacil name can be found in the parish records of the town of Klatovy in western Bohemia, dated around 1580. The name was also present in other regions of the Czech lands, including Moravia and Silesia, during the 16th and 17th centuries.
During the Middle Ages, the Nesvacil name appeared in various spellings, such as Nesswaczyl, Nesswaczil, and Nesswaczell, reflecting the linguistic variations and regional dialects of the time. It is worth noting that the name does not seem to have any direct connection to specific place names or localities.
In the late 18th century, a notable figure bearing the Nesvacil name was Jan Nesvacil (1742-1825), a Czech author and educator who published several works on linguistics and educational reform. Another prominent individual was Alois Nesvacil (1841-1912), a Czech lawyer and politician who served as a member of the Moravian Diet.
Other historical figures with the Nesvacil surname include:
1. Antonín Nesvacil (1876-1941), a Czech painter and illustrator known for his landscapes and portraits.
2. František Nesvacil (1892-1942), a Czech engineer and inventor who contributed to the development of early radio technology.
3. Jaroslav Nesvacil (1927-2005), a Czech film director and screenwriter, best known for his adaptations of literary works.
4. Vojtěch Nesvacil (1859-1933), a Czech architect who designed several notable buildings in Prague and other Czech cities.
5. Zdeněk Nesvacil (1924-2016), a Czech athlete and Olympic medalist in gymnastics, who won a silver medal at the 1952 Summer Olympics in Helsinki.
While the Nesvacil name has its roots in the Czech lands, it has since spread to other parts of the world through migration and diaspora communities. However, its historical significance and connections remain firmly rooted in the cultural and linguistic heritage of the Czech Republic.

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