June 2, 1935, and to the parents you mention.
I do not know about the origins of this branch of the Efrons, but I do have
some other information. In some records for 1907, there is an Avigdor, son
of Meyer; also, there is a Shlema, son of Avigdor. Vigdor Meyerov (the way
the name is said in Russian) is a real estate owner. Shlema Vigdorov (the
way the name is said in Russian) is an apartment owner.
My guess is that the family tree is like this:
Meyer, father of:
Avigdor, father of:
Shlema and Benjamin. Benjamin is the father of Avigdor.
