I am trying to find information on my great uncles that remained in Mogilev after my grandfather Louis Berlin immigrated to NY. These were two letters that were written. I was told that the brothers names were possibly Leon and Charles Berlin. One letter was on the back of a military photograph. Also is the military photograph the uniform of the Russian army? 

Thank you
