Origin
Meaning and origin of Koshinsky
The surname Koshinsky is of Eastern European origin, originating from regions in present-day Poland, Ukraine, and Russia. It is derived from the Slavic root "kosh," meaning a type of basket or wicker container. This suggests that the name may have originally referred to an occupation or trade involving basket weaving or a similar craft.
One of the earliest recorded instances of the name Koshinsky can be found in the Polish town of Koszyn, dating back to the 16th century. The town's name is believed to be a variant of the Slavic word "koshka," meaning a small basket or container. It is possible that the surname Koshinsky emerged from this place name, with families adopting it as a means of identifying their place of origin.
In the 17th century, records show a Koshinsky family living in the city of Lviv, which was then part of the Polish-Lithuanian Commonwealth. This suggests that the name had spread beyond its initial region of origin and was becoming more widely established.
During the 18th century, the name appeared in various Russian imperial records, indicating that Koshinsky families had migrated or been displaced to different parts of the Russian Empire. One notable figure from this period was Ivan Koshinsky, a merchant and landowner who lived in the Smolensk region from 1723 to 1789.
As the 19th century dawned, the Koshinsky surname continued to disperse across Eastern Europe. A prominent individual was Mikhail Koshinsky, a Russian military officer who served in the Crimean War (1853-1856) and later became a governor in the Caucasus region.
In the early 20th century, a Ukrainian poet and playwright named Oleksandr Koshinsky (1886-1937) gained recognition for his works exploring themes of rural life and social justice. His literary contributions helped to further establish the Koshinsky name within Ukrainian cultural circles.
Other notable individuals with the Koshinsky surname include Fyodor Koshinsky (1906-1976), a Soviet chess grandmaster and author of several influential books on chess theory, and Irina Koshinska (1924-2010), a renowned Russian ballerina and choreographer who performed with the Bolshoi Ballet for many years.

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