Hi Richard, I have two Rudolf Hunziker's in my database, but they are born 1712 and 1753. The first is the father of the second. This first Rudolf Hunziker is brother to my Valentine Hunziker. He was born in Shoftland, Aargau, Switzerland.I am not sure if this will help you. I have a film at the LDS. Have you tried Die Hunziker von Aarau by Oehler? The film # is 1045324, Item 1. Another is 0564386, Item 1. If this doesn't help, I would visit your local LDS for advise from the Librarian.
Father of first Rudolph was Samuel Hunziker. I wish you luck in your research of our Hunziker name.
