This suggests that the name may have been initially given as a descriptive nickname to someone with a squint or crossed eyes.

One of the earliest recorded references to the KOSOY surname can be found in the tax census records of the Ryazan region of Russia, dating back to the late 17th century. These records mention a certain Ivan Kosoy, who was a landowner in the village of Novoseloye.

In the 18th century, the KOSOY surname appeared in various church records and parish registers across central and western Russia, indicating that the name had spread to different regions by that time.

In the late 19th century, the KOSOY surname was also found in Ukraine, which was part of the Russian Empire at the time. One example is Mykhailo Kosoy, a Ukrainian painter and art teacher who lived from 1865 to 1925.

Moving into the early 20th century, Nikolai Kosoy (1891-1957) was a Russian-born engineer who played a significant role in the construction of the Moscow Metro system in the 1930s.
