Unfortunately you give very little information as far as family names and dates are concerned. I suggest you consult the Jewishgen Family Finder . Also when doing a search remember that in Russian there is no H so you should  search for Haiman, Heiman.,Geiman,Gaiman.  I had a look at the Internal Passports on Citlskoki and there were quite a lot of names spelled the way I have indicated.  checked a few but  you would be best placed to look as you might recognise other family names.

Once you have a username and password use the site in Latvian not English.  Enter in the first box which is surname Geiman and leave the Town Box empty. Look at all the hits both Geiman and Heiman.
