I recently found an old envelope that Frederick HERRMANN (or HERMANN) of Vernon Center, Oneida County, NY of received from Colmar, France in 1864. You can see the envelope on www.philgen.org (search on Vernon, click on View, and scroll to the bottom of the page). I want to determine if Colmar, France is the birthplace of Frederick HERRMANN and if this envelope is helpful to someone in their genealogical research. I do not know if the letter that was in the envelope still exists.
