Hi, I realize this reply is a few years old, but, I am hoping you are still on the site and can provide answers on the Oexmann connection.
You mentioned that you have family history on all the Oexmann sons and their parents.
Are you able to send me copies of your findings?
I'm still looking for much info on Fred and William Oexman of Indiana and hoping your efforts can provide some enlightment.
A few years ago I was in touch with Georgia Halter who authored a family book on August Oexman, but I don't have any of the particulars. I have asked the Knox County Lib to copy the info from the book and send to me. However, any/all info you could provide would be AWESOME!
