For those families who immigrated to the US or Canada from Russian and Eastern European towns circa 1900, their elders rarely made the trip. Obtaining town vital and cemetery records, many destroyed during the Holocaust, is quite a challenge but not impossible.
May I suggest the best way for you to learn about this family is to take a genealogy class through www.jewishgen.org
. They have expert instructors that teach research methodologies, suggest reference sources, and guide you to making family discoveries. The typical online class duration is one month and you can choose to move onto more advance classes such as Eastern European Research. They also have databases at their web site, and an online discussion group.
