Origin
Meaning and origin of Krchmar
The surname Krchmar is of Czech origin, deriving from the old Slavic occupational term "krčmář" meaning "innkeeper" or "tavern owner." This name first emerged in the 14th century in the regions of Bohemia and Moravia, which were part of the Holy Roman Empire at the time.
One of the earliest recorded instances of the name Krchmar can be found in a land registry from the town of Kutná Hora, dated 1382, which mentions a certain Jan Krchmar as a landowner. The name also appears in various municipal records and tax rolls from the 15th and 16th centuries in cities like Prague and Brno.
In the 17th century, the Krchmar family gained some prominence when Václav Krchmar (1628-1703), a prominent merchant and alderman, served as the mayor of the town of Mladá Boleslav for several terms. His son, Jakub Krchmar (1662-1722), was a noted theologian and author of several religious texts.
Another notable figure bearing this surname was Jan Krchmar (1785-1865), a Czech writer and journalist who played a significant role in the Czech National Revival movement of the 19th century. He was a staunch advocate of the Czech language and culture and contributed numerous articles and essays to various publications of the time.
During the 19th and early 20th centuries, the surname Krchmar was also found in various parts of the Austro-Hungarian Empire, including regions such as Moravia, Silesia, and Galicia. One such example is Karel Krchmar (1870-1942), a Czech-Austrian architect who designed several notable buildings in Vienna and other cities in the empire.
In more recent history, the name Krchmar has been associated with notable figures such as Jindřich Krchmar (1920-2003), a Czech chemist and inventor who held several patents in the field of polymer chemistry, and Jaroslav Krchmar (1928-2008), a Czech film director and screenwriter known for his contributions to the Czechoslovak New Wave cinema.

The bar chart below shows how Krchmar 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 Krchmar surname at the time of the 2020 Census, not any inherent property of the name itself.
