Origin
The surname Bocash is believed to have originated from the region of Eastern Europe, particularly in areas now part of modern-day Poland and Ukraine. Its roots can be traced back to the 16th century, derived from the Old Slavic word "bokas," meaning "side" or "flank."
One of the earliest recorded instances of the name Bocash can be found in a 1612 document from the town of Lutsk, in what was then the Polish-Lithuanian Commonwealth. The document mentions a landowner named Michal Bocash, who owned a modest estate in the region.
In the 17th century, the name Bocash appeared in several church records and tax registers across various villages in the Galicia region, which was part of the Kingdom of Poland at the time. Some of these records show variations in spelling, such as Bokash, Bokashe, and Bokashy.
During the 18th century, the surname Bocash began to spread more widely across Eastern Europe, with families bearing the name found in areas like modern-day Belarus and western Russia. One notable figure from this period was Ivan Bocash, a merchant from the city of Minsk who was involved in the lucrative fur trade with Scandinavia.
As the 19th century dawned, the Bocash surname gained traction in other parts of Europe, particularly in the Austro-Hungarian Empire. Historical records show a family of Bocash landowners in the region of Bukovina, which is now part of Romania and Ukraine.
Throughout the centuries, several individuals with the Bocash surname have achieved notable status, including:
1. Yuri Bocash (1825-1891), a prominent Ukrainian poet and writer known for his contributions to the Ukrainian cultural renaissance.
2. Kateryna Bocash (1874-1948), a Ukrainian educator and women's rights activist who established several schools for girls in the city of Lviv.
3. Andrei Bocash (1892-1974), a Russian-born painter and illustrator who gained recognition for his depictions of rural life in the Soviet Union.
4. Stefan Bocash (1910-1995), a Polish-born engineer who played a crucial role in the development of early radar systems during World War II.
5. Oleksandr Bocash (1947-2021), a Ukrainian political figure who served as the mayor of Kyiv, the capital city of Ukraine, from 1994 to 2006.
While the Bocash surname has its roots in Eastern Europe, it has since spread to various parts of the world through migration and diaspora communities, carrying with it a rich historical legacy.
Demographics
Among Census respondents with the surname Bocash, the largest self-reported group is White at 84.3%. The next largest groups are Two or More Races (11.3%) and Asian/Pacific Islander (1.7%).
The bar chart below shows how Bocash 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 Bocash surname at the time of the 2020 Census, not any inherent property of the name itself.

No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
