About Josef Wurmfeld
Sons Adolf and Josef born in Nemesszalok.
The obituary of Rozália Schöntag (Frankl) is a pretty exhaustive list of surviving family, including her brothers David, Ignac and Adolf and the wives of David and Ignac. It does not mention a bother Josef although he would have been alive. This implies that perhaps there was another couple named Josef and "Hanni" or "Fanni" Wurmfeld, but he this Josef Wurmfeld, is probably not the same as the József Wurmfeld, spouse of Johanna Rosenberger, who lived in Graz and Szombathely.
I have not yet been able to find the records of Nemesszalok.
