Hi Paul! Very nice to hear from you ~ it's been awhile!:-)
I do believe after all these years, I have found my Catie's owner -- Madison Derrelle CODY (the Warren Co. Rep for the Confederacy). I have much of the discovery process posted to my OGR blog (http://ourgeorgiaroots.com/?p=920
I now need to return to the archives to dig deeper into the letters/docs the GA Archives have on film. I had read them [quickly] before, of course this was before I realized the connection to my Catie.
