Grandmother & Father immigrated from Russia/Poland in 1913, from listed location of Jesnayewa, Russia/Poland. have not been able thus far to find this town/city to further advance information of family roots! Traveled under the name Kloc...to New York...finally to Shamokin, Pa.
My favorite site for finding place names in Russia and Europe is geonames. "http://www.geonames.org/advanced-search.html?"
Use the advanced search with the "fuzzy" search selected -- I've found it will present me with a result that includes the placename that I'm looking for.
Take a look at each of these places and see if they may be located in an area that is familiar.
