I myself am originally from Clay Co., and my mother was a Kitch. One of Nathanial's daughters came to our Kitch reunion on a regular basis and lives not far from my parents. I'm more interested in the Kitch's, but will see if I can come up with some info or local (Clay Co.) contacts for you concerning the Addy's. Are you by any chance from Indiana yourself? Contact me at firstname.lastname@example.org.
