Genealogy / Looking for info. on my g. grandfather Isak Schachner's Family and the town Jordanow. [4]

Hi everyone!

I am new to this forum, so sorry if its not written properly.

I am looking for information on my great gandfather Isak Schachner (Szachner) from Jordanow and his family.

Isak Schachner had a store in Jordanow that sold farming machines and tools (SKEAD MASZYN).
He is listed in the 1929 Polish Business Directory as Isak Szachner, Maszyny, rolnicze (machines agricoles): Schachner I.

Only his son Oscar (Ozjasz) Schachner survived the war and emigrated to America.

Thanks,

Shloimie
