Just saw your message of a year ago. Do you know the names of Jacob Yunker's (Junker) parents? Martin Yunker (Junker) also came from Bavaria - Krombach in Herbipoli (Wurzburg) diocese. I just found where he came from in June so it has opened up a whole new research area. Maybe they are related. My e-mail address is ljy@nycap.rr.com
