Many thanks to those who responded so quickly (and most of you
correctly). I thanked you directly. How I did not think myself about
this possibility? It seems most certain that the right spelling is
HEUBERGER (HEUBERGER). There are quite a number of them in
Brzesko, Bochnia and Tarnow. Now I have to go back to the
traditional methods to find out the B&M of Cheskiel HEUBERGER.
