I'm still looking but I did find a Kolin in Czech Republic but that was never part of the Soviet Union as far as I know. I also looked to see if the "K" was maybe an "R" or maybe that the Kolin and Kovitz were two different words, also swapping out "Ks" for "Rs".
No dice. I did happen to come across this for a guy named Joseph Ackerman who was born October 15th, 1890 in Kolinkovitz, Russia.
