Hi, are you still looking for relatives of Moshe Velvel?
I am the great , great grandson of a Moshe Velvel Feigenbaum via my maternal grandfather. His name was Mordko Bezalel Rubinstein, and his mother Tilly was Moshe Velvel's daughter (she married Menachem Mendel Rubinstein). Mordko's wife was Pajka Freiburg. They were all born in Parcew Poland as was my mother. They left Poland in 1933 for South Africa.
