I've just learned that my paternal grandparents, Avraam Shekhter and Khiena Telishevskaya, married in Ekaterinoslav (now Dnipropetrovsk) in 1903. Both hailed from the Gomel/Mohilyov region (not only per what I know, but per their marriage record), so I'm not sure how they came to be married in Ekaterinoslav - maybe one or both of their families had moved there?
Any clues will be highly respected!
