The Auman family is still in Galena. In fact Dick Auman who was our mayor for two terms just took a shot at a senate seat from our district. Dick has info. about the Auman Rootbeer. Also, the Galena/Jo Daviess History Museum received a donation about 7 years ago that included Auman family artifacts about their syrups.
Dick would be in the Galena phone book. The Museum website is www.galenahistorymuseum.org
and their phone number is 815 777-9129. Good Luck!
