I am writing to request your help in how to approach the following
My relative was born in Moscow, Russia in 1946. His mother probably died
during the birth, and he was taken as an orphan to Israel and was brought up
in Mea Shearim, Jerusalem. He was adopted by the Head of the Hebron Yeshiva,
and was given a name -- Ze'ev Cohen. Ze'ev never knew his father who was
probably named Meir ZWARTZBAT (black beard), and was a key activist in the
Russian Jewish Community that was taken to Siberia in 1945-6. His uncle
(father's brother) was a famous Shochet in Russia.
