My paternal great grand father, Simha Karasik, was a merchant. His son (and my grand father), Moyshe S. Karasik was born on May 10, 1893. Later he was going by the Russian version of his name Moisej.
Moisej Karasik was drafted during WWI and served in cavalry. He was awarded Cross of St. George for the service.
Grand dad was also drafted during WWII and served as a sapper. He was killed in action on August 28, 1943.
