Menachem Mendel Biber's book "Mazkeret Legedoley Ostraha" mentions two
Rav Yisrael of Ostraha, which he presumes they are one and the same.
As I am a descendant of one of these Yisraels , I would like to share
information with others what I have on our tree.
My greatgrandfather's granfather, Yisrael, (ROSENBAUM but Biber
doesn't mention the family name) was a follower of Yehoshua Heschel of
Apta and came to Zfat and or Tveria during the first half of the 19th
cent. Some of his descendants changed their family name to SCHECHTER
as to their profession in Europe.
