Also, you can search The JewishGen Family Finder
https://www.jewishgen.org/jgff/
to look for other people researching your town, and anyone searching your surnames of interest.

You can search for records from the town at The JewishGen Ukraine Database.
I suggest using a phonetic or soundex search on surnames, as names get transliterated in various ways.

Good luck in your search,
