I've been traveling so I am late to reply. Our family root name is TSIFRIN. We are from Belogorodka, Ukraine. My husbands maternal side is from Kamenetz-Litovsk, Ukraine. The Zeffren's immigrated to St. Louis via Rock Island, IL. The Shifrin's were the only branch of that greater family going directly to St. Louis. At first glance, we are not from the same family, HOWEVER, I never overlook "close, but not quite" situations. My email address is firstname.lastname@example.org
if you wish to go further.
Best of luck to you,
