I am interested in research for two towns in Kherson gubernia - Kherson and Nikolajev. I have made a request to State Archieve of Kherson region and got a reply >from them. The archieve wrote that they have got for Kherson only revizion lists for 1858 and some metric books for 1837 - 1865 of some synagogs (not all). Not so much. ( but it doesn not mean that they do not have other documents which contain genealogical information).
I could participate in translating records for these two towns and small shtetels around them.
By the way, I know that usually archieves send a copy of only one side of birth and marriage books . Does anybody know if jewish books contain the other side of these records, where in orthodox books we can find info about "vospriemniki" (for births) and "svideteli" (for marriages) - they were usually close relatives and information about them helps much in finding links between ancesters .
