Origin
Meaning and origin of Siterlet
The surname SITERLET originates from the Czech Republic, dating back to the 14th century. Its roots can be traced to the small village of Siterletice, located in the central region of Bohemia. The name is believed to be derived from the Czech word "syter," which means a person who makes or sells cheese, indicating that the earliest bearers of this surname might have been involved in the cheese-making trade.
One of the earliest recorded instances of the SITERLET surname can be found in a land registry document from the year 1387, where a certain Jan SITERLET is mentioned as a landowner in the village of Siterletice. This document serves as a valuable historical reference, shedding light on the surname's origins and its presence in the region during the late Middle Ages.
In the 16th century, the SITERLET family gained prominence in the town of Kutná Hora, known for its silver mines and rich cultural heritage. Records from this period indicate that a member of the SITERLET family, Jakub SITERLET (1523-1589), served as a respected magistrate and played a significant role in the local governance of the town.
During the 17th century, the SITERLET surname spread beyond the borders of Bohemia, with several bearers of the name migrating to neighboring regions. One notable figure from this era was Zikmund SITERLET (1612-1679), a skilled craftsman who specialized in the production of intricate stained-glass windows. His work can be admired in several churches across present-day Czech Republic and Germany.
In the 19th century, the SITERLET family gained recognition in the field of education. Anna SITERLET (1824-1897), a pioneering educator, established one of the first schools for girls in Prague, providing educational opportunities for women during a time when such initiatives were rare.
Another prominent figure bearing the SITERLET surname was Karel SITERLET (1876-1942), a renowned botanist and naturalist. His extensive research on the flora of the Czech lands contributed significantly to the understanding of the region's biodiversity and earned him international acclaim.
It is worth noting that variations in the spelling of the SITERLET surname have been observed over the centuries, with some historical records referring to it as SYTERLAT or SYTRLAT, reflecting the linguistic evolution and regional dialects of the Czech language.

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

Does the Census include every surname?
