I am descended from Hartmann Hunziker, of Switzerland. The family is very well documented there back to the 1500's. I am currently researching this line also, and have data on Hartmann and family. Just yesterday I began reviewing some records on this line that I ordered from the family history center. These records include their pedigree back to the 1500's, in Aarau, Switzerland. I haven't yet documented this new data because I just started reading it, so I'm not sure if I can offer you any info you have not already found in this forum, but feel free to contact me.
