My family is from Talking Rock, GA In fact, I've heard my grandma talk about Preston, as her husband was Aden Keeter
Aden Keeter married Barbara Keeter, had four children. I'm the second daughter of their oldest
As for the Keeters being from Georgia, all I know is that Meredith Keeter still lives in Talking Rock (or at least she did when I was there a few years back) and I believe that she's Aden and PReston's cousin? Not quite sure!
Let me know if you find out anything - it seems to be a bit of a dead end for some reason!
