Hanan (or Elhanan) Eliezer Weisinger fathered Tzvi Hersh Weisinger (I don't know of other children). Tzvi Hersh Weisinger fathered 13 kids (I have details of 12 of these, one died as an infant whoes details I lack). I am the grandson of one of one of these 13 kids (Menachem Mendel). All family histories prior to Tzvi Hersh only include the names of these parents and nothing else. Please help.
