Origin
Meaning and origin of Kuncl
The surname KUNCL is of Czech origin, originating in the regions of Bohemia and Moravia during the medieval period. It is believed to have derived from the Czech word "kunc," which means a rabbit or a hare, suggesting that the name may have been initially given as a nickname to someone who resembled or had a characteristic associated with a rabbit.
One of the earliest recorded instances of the name can be found in the Liber Viridis, a medieval register of land holdings and settlements in Bohemia, dating back to the 14th century. The name appears as "Kunczl," which is an early spelling variation.
In the 15th century, the name is mentioned in the Hussite Chronicles, which document the Hussite Wars in Bohemia. A certain Jan Kuncl is listed as a participant in the battles against the Catholic forces, though his specific role or background is not clearly detailed.
During the 16th century, the name appears in various municipal records and tax rolls across Bohemia and Moravia, indicating its widespread use among the Czech population. Notable individuals from this period include Václav Kuncl (1525-1589), a prominent merchant and landowner in the town of Kutná Hora.
As the name spread throughout Central Europe, it also found its way into other regions, including present-day Slovakia and Austria. In the 18th century, a notable figure was Josef Kuncl (1720-1798), a Moravian composer and organist who contributed to the development of sacred music in the region.
Another significant individual was Karel Kuncl (1838-1918), a Czech architect and urban planner who played a crucial role in the development of Prague's modern cityscape. His most notable works include the design of the Municipal House and the renovation of the Old Town Square.
Other notable individuals with the surname KUNCL include Jaroslav Kuncl (1892-1964), a Czech painter and illustrator known for his depictions of rural life and landscapes, and Josef Kuncl (1903-1979), a Czech writer and journalist who documented the experiences of World War II.
While the surname KUNCL may have originated as a nickname, it has since become a well-established surname in the Czech Republic and surrounding regions, with a rich history and notable individuals across various fields.

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

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.
