Origin
Meaning and origin of Cesko
The surname Cesko has its origins in the Czech Republic, and is believed to have first emerged during the 12th century. It is derived from the Old Czech word "čeští", which means "Czech" or "from Bohemia". This name was likely given to individuals who migrated from Bohemia to other parts of Europe.
One of the earliest recorded instances of the surname Cesko can be found in a 13th-century manuscript from the Cistercian monastery in Sedlec, near Kutná Hora. The document mentions a certain "Jan Cesko", who was a landowner in the region.
During the 15th century, the name appeared in several records from the cities of Prague and Brno. For example, a merchant named "Vaclav Cesko" is listed in the tax records of Prague from the year 1487.
In the 16th century, the surname Cesko began to spread to other parts of Europe as Bohemian settlers and merchants travelled westward. One notable individual from this period was "Jiri Cesko" (1523-1588), a Protestant reformer and theologian who studied at the University of Wittenberg and later became a professor at the University of Prague.
The 17th century saw the emergence of the Cesko family in the village of Velké Popovice, near Prague. This family produced several notable figures, including "Frantisek Cesko" (1612-1679), a renowned mathematician and astronomer who worked at the Prague Observatory.
In the 18th century, the name Cesko appeared in various records from the German-speaking regions of Central Europe. One example is "Johann Cesko" (1735-1798), a successful merchant from the city of Dresden who traded in Czech glassware and textiles.
Throughout history, the surname Cesko has been associated with several notable individuals, including "Karel Cesko" (1842-1919), a Czech composer and conductor who wrote numerous operas and orchestral works, and "Olga Cesko" (1875-1948), a pioneering Czech female writer and journalist who campaigned for women's rights and education.

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