I'm trying to find any information about my grandparents and uncles.
The names are Leizer and Raisa Rapoport, Izaak Rapoport, and Pessakh Rapoport and wife Sara.
They also had an apartment in Mylna 5, Warsaw.
Leizer was a jewellery trader(?), Izaak was a Rabbi/teacher, and Pessakh an accountant(?)
They lived there in the 1920s and 1930s.
Can anybody help?
