Hi Charla -- I can't help you with getting the information you are looking for, but I found your post really interesting. My father was Charles Michael Alexander and my grandfather was Charles Edward Alexander, born and raised in Gallatin TN.
My grandparents divorced when my father was very young and I didn't have much contact with my grandfather other than the occasional birthday or holiday card, but interestingly enough, my grandmother married my great uncle, C.E.'s brother, and he was the only grandfather I knew.
Sorry for the unhelpful rambling, all I know about that side of my family is that we're related to Lamar Alexander and some senators from Arkansas and that the Alexanders are from Gallatin.
I'd love to chat with you about whatever you've found out and perhaps help if I can. Please feel free to contact me if you'd like. Good luck in your search. --Katie Jones
