The Hofman/Zylberman Families

We have just begun the search. A search we already know will take us across the world to many distant places.
With the recent passing of my grandfather and all my grandparents now gone, I would like to finally organise all the stories and information they have passed to us in their lives.
I am researching the Zylberman and Hofman familes whose origins are in Poland as far as I can tell.The bulk of the family currently are now living in Israel, Brazil and Australia.
