Origin
Meaning and origin of Bohensky
The surname BOHENSKY is of Czech origin, tracing its roots back to the medieval era in the region of Bohemia, which is now part of the modern-day Czech Republic. The name is derived from the Old Czech word "bohemský," meaning "Bohemian" or "of Bohemia."
One of the earliest recorded instances of the BOHENSKY surname can be found in the Codex Diplomaticus et Epistolaris Regni Bohemiae, a compilation of historical documents and records from the 13th to the 15th centuries. This collection mentions a certain "Václav Bohensky" who lived in the town of Litomerice in the late 14th century.
The BOHENSKY name was also present in the Zemské desky, a series of land registers and legal records maintained in Bohemia from the 14th to the 17th centuries. These records document various landholdings and transactions involving individuals bearing the BOHENSKY surname during this period.
In the 16th century, a notable figure named Jan BOHENSKY (1524-1590) was a prominent Protestant reformer and writer in Bohemia. He played a significant role in the spread of the Hussite movement and the translation of religious texts into the Czech language.
Another historical figure was Jakub BOHENSKY (1638-1718), a Baroque architect and builder who was responsible for the construction of several churches and monasteries in Prague and other parts of Bohemia during the 17th and early 18th centuries.
During the 19th century, a distinguished member of the BOHENSKY family was Karel BOHENSKY (1815-1892), a Czech politician and journalist who advocated for Czech national rights and democracy. He was a prominent figure in the Czech National Revival movement and served as a member of the Bohemian Diet (parliament).
As the BOHENSKY surname spread beyond its origins in Bohemia, it has been associated with various place names and older spellings, such as Bohenski, Bohenskey, and Bohensk. However, the core meaning and connection to the region of Bohemia have remained consistent throughout its history.

The bar chart below shows how Bohensky 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 Bohensky 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.
