Kaganovich's son's last name was Mikhail.

You mean first name, right? His son's last name was Kaganovich, just like his own. By the way, in this scenario I changed his son's first name since I figured Kaganovich would want to name his son after him if he was dictator of the Soviet Union instead of just Stalin's lackey.
