Origin
Meaning and origin of Poslusny
The surname POSLUSNY has its origins in the Czech Republic, tracing back to the 15th century. It is derived from the Czech word "poslušný," meaning "obedient" or "compliant." This suggests that the name may have been initially given to someone known for their obedient nature or willingness to follow orders.
POSLUSNY is believed to have originated in the region of Bohemia, which was a part of the Kingdom of Bohemia during the medieval period. The name appears in several historical records from that time, including church registers and tax rolls.
One of the earliest recorded instances of the POSLUSNY surname can be found in a 1457 document from the town of Litomyšl, where a man named Jan POSLUSNY is mentioned as a landowner. Another notable early reference is in the Codex Gigas, a 13th-century manuscript from the Benedictine monastery in Břevnov, which includes a list of names, including POSLUSNY.
In the 16th century, the POSLUSNY name was also associated with the city of Kutná Hora, a mining town known for its silver mines and architectural marvels. Records from this period show several POSLUSNY families living and working in the area.
One of the earliest notable individuals with the POSLUSNY surname was Vavřinec POSLUSNY (1525-1592), a Catholic priest and theologian who served as the rector of the University of Prague. Another prominent figure was Jiří POSLUSNY (1568-1624), a Bohemian nobleman and military commander who fought in the Thirty Years' War.
During the 17th and 18th centuries, the POSLUSNY name spread beyond Bohemia to other regions of the Czech lands and the Habsburg Monarchy. Notable individuals from this period include Jan POSLUSNY (1654-1718), a Czech painter and engraver known for his religious works, and František POSLUSNY (1721-1788), a Czech composer and organist who worked in the court of Maria Theresa.
In the 19th century, the POSLUSNY surname continued to be prevalent in the Czech regions, with several individuals making contributions in various fields. One such notable figure was Antonín POSLUSNY (1823-1892), a Czech writer and journalist who played a significant role in the Czech National Revival movement.

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