Help with research in Kiev during Soviet era #general #ukraine

Michael Moritz

I would be grateful for help with research in the city of Kiev. I am researching brothers who were born in Skvira in 1913 and 1921, who later, by the beginning of the war, moved to Kiev. Their names were Rakhmil and Yakov Kozlov.

I am trying to find out the whereabouts of their father Joseph Kozlov and I want to determine the name of Joseph's father. I know that Joseph was born approx. 1885 either in Bila Tserkva or in Volodarka, and his wife's name was Enya Segal. I think they died, most likely, in Kiev, and if not in Kiev, then in Skvira. Any help would be appreciated, thanks!
