I am tracking my paternal grandmother and paternal grandfather's families. Today I discovered that they both seem to be living in the same apartment building in Dvinsk.
In the abstract via JewishGen, Geisa Koblenz, age 40, and her children (including my grandfather) has the family living at "Dvinsk Naberezhnaya, house of Schapiro, 2706-1-42 234 "
In a different search, I found Mowscha Bun and his wife Ele (my great grandfather and step great grandmother) living at "Dvinsk Naberezhnaya, house of Schapiro, 2706-1-42 350 "
The 234 and 350 refer to sheet numbers.
So can anyone help me understand if they were living in the same building or not?
