I'm vaguely familiar with the letter of dismissal you mentioned. I have a copy somewhere on one of my many CD's, but Eliza was dead by t1838. She died in 1834. She married James Wallace around 1819. My 2great grandfather Robert was born in 1820. Eliza may have died in childbirth because Gordon was born about 1834.
Do you know where Nancy Hunter Adkins is buried? I've asked on a couple of mailing lists and received no reply.
