I discovered yesterday that my grandfather had a sister called Ettel ROSNER in Zabno, Galicia. She married around 1890 Emanuel Kurz and had at least 5 children whose names and exact birth
dates I located in scans in the Polish Archives. Tried to find out what happened with them in the Holocaust. In the GEDENKBUCH I found one of them: Chaskel ROSNER born in Zabno on Dec.
17,1898(the dates match). He apparently kept his mother's surname. He lived in Dusseldorf and was expelled to back to Poland in 1938 with a son called Max born in Dusseldorf on July 2nd 1928.
No wife is mentioned. I shall appreciate any details about his address, profession and spouse in Dusseldorf.
