Hello !
Thank you for your answer.
Yes, Preissig hebrew name was Pessah.
I have sent the document for a translation, unfornutatly I don't read or speak hebrew.
I have asked for the death certificates of Preissig and Zierel, I don't know where they were born.
Szyla-Wolf married my Gdmother Chaya born MELZAK.
According to the family, she was born in Warsaw, her parents were killed, she passed time in an orphanage and was adopted by Itzhak Nozik (I think he was a man of theatre). They emigrated to Israël too.
When Chaya and Szyla-Wolf (hebrew name Zeev) married in Israël, they changed the name Huaptmann into Hoftman.
I was born Hoftman.
I hope this will help us !
Sharon.
