Origin
Meaning and origin of Rokosky
The surname Rokosky is of Slovak origin and dates back to the 16th century. It is believed to have originated from the Slovak regions of what is now modern-day Slovakia and parts of eastern Hungary. The name is derived from the Slovak word "rok," meaning "year," and the suffix "-osky," indicating a place of origin or residence.
One of the earliest recorded instances of the name Rokosky can be found in the parish records of the village of Rokosov, located in the Prešov region of eastern Slovakia, dating back to the late 1500s. The name's connection to this village suggests that the bearers of the name may have originally hailed from or resided in this area.
In the 17th century, the name Rokosky appeared in various legal documents and property records in the towns of Košice and Prešov, indicating the presence of individuals bearing this surname in these urban centers of the region.
In the 18th century, a notable bearer of the name was Ján Rokosky (1725-1803), a Slovak priest and scholar who authored several works on theology and philosophy. Another significant figure was Michal Rokosky (1772-1848), a Slovak poet and writer who played a crucial role in the Slovak national revival movement.
The 19th century saw the name Rokosky spread beyond Slovakia, with individuals bearing this surname migrating to other parts of Europe and North America. One prominent example is Andrej Rokosky (1856-1924), a Slovak-American journalist and community leader who founded several Slovak-language newspapers in the United States.
In the early 20th century, the name Rokosky gained recognition through the works of Ján Rokosky (1889-1968), a Slovak painter and art teacher who was renowned for his landscape and still-life paintings.
Throughout its history, the surname Rokosky has maintained its roots in the Slovak regions, although its bearers have dispersed and contributed to various fields, including religion, literature, art, and journalism.

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