I don't know if you still need information on Wolfgang Bader or not.I have been researching my Baders and found a Wolfgang Bader who was christened around 3/13/1579 in Switzerland. I think Basel? His parents are listed as Claus Bader and Barbara Bonner Bader. They were married 5/16/1568 in Basel. They had 10 children. Claus born possibly about 1548.
