Bernhard Moschkowitz - Date of death

I do not believe we have seen any birth records for him. Not sure. Does anyone have a copy of his tombstone? His age or date of birth may be on it.

Do you know where my great-grandmother Jenny she lived in germany when she died?

Is this the Jenny you are asking about:
Jenny Rosenkranz

Yes. I have a problem. My lawyer did not find any document of my family in Berlin, and I can't understand it because I showed my father's German passport and my grandmother receive compensation from Germany until her death.
That is the reason why I am trying to find any informatin that proves that my family comes from Germany.
