Origin
Meaning and origin of Kusman
The surname Kusman is believed to have originated in the Czech Republic, with its roots dating back to the 13th century. It is derived from the Old Czech word "kus," which means "piece" or "fragment," suggesting that the name may have been associated with an occupation or trade involving the cutting or shaping of materials.
One of the earliest recorded instances of the Kusman surname can be found in the Codex Diplomaticus et Epistolaris Regni Bohemiae, a collection of historical documents from the Kingdom of Bohemia dating back to the 12th century. In this text, there is a reference to a man named Kusman, who was a landowner in the region of Moravia in the year 1258.
The name Kusman has also been linked to various place names in the Czech Republic, such as Kusmany, a village located in the Vysočina Region. This connection suggests that the surname may have originated as a locative name, indicating the place of origin or residence of the family.
Throughout history, several notable individuals have borne the Kusman surname. One such figure was Jan Kusman (1572-1629), a Czech mathematician and astronomer who made significant contributions to the field of celestial mechanics. Another was Václav Kusman (1801-1876), a Czech composer and music teacher who was influential in the development of Czech classical music during the 19th century.
In the realm of literature, the name Kusman is associated with Jarmila Kusmanova (1892-1958), a Czech writer and journalist who was known for her novels and short stories depicting the lives of ordinary people in rural Bohemia.
Other notable individuals with the Kusman surname include Karel Kusman (1903-1972), a Czech painter and graphic artist known for his avant-garde works, and Jaroslav Kusman (1931-2007), a Czech actor and playwright who had a successful career in both theater and film.
While the Kusman name has its roots in the Czech Republic, it has since spread to other parts of the world through migration and diaspora communities. However, its origins and historical significance remain deeply rooted in the region's linguistic and cultural heritage.

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.

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
