I'm looking for resources to find archived documents on my great grandparents from Berdychiv, Ukraine. They lived there from at least 1830 till around 1906. The surnames were Iserov and Grinberg. I have found the Lipes Data Base online as well as the Tsal Kaplan Foundation. Lipes charges a lot for just one document and Tsal Kaplan doesn't have the option to search through documents as of yet. I don't read Russian or Ukrainian so even once I find the right place for the documents, I would need a translator. For anyone who has experience in this area of Ukraine: what is your advice to take the next step on this search?
