In case anyone is interested, a well-published Swiss genealogist, Dr. Peter Steiner, is the director of the Historische Vereinigung Wynental (Wynental Historical Society). The Wynental is the the Wyne River Valley region of Aargau. This is the area from which at least one branch of Hunzikers emigrated.
Membership is fairly nominal -- I believe that at recent exchange rates the annual fee was less than $10.
The internet address (most content is still in German but is being translated) is http://www.hvw.chhttp://www.hvw.ch
I do not have any affiliation with Historische Vereinigung Wynental or Dr. Steiner other than some past correspondence. I just thought that others might be interested, especially if planning a trip to Aargau.
