I have some information on your Duttons. I have some firm evidence that Alexander Dutton of Madison Co., Mississippi Territory was the son of Zachariah Dutton (b. ca. 1750? in Charles Co., Maryland, died 1829 in Granville Co., N.C.). I run the DUTTON-ZACHARIAH-L mailing list at RootsWeb. We have at least one or two other members who are descendants of Alexander Dutton and Rachel Feazel.
I don't have a whole lot on Alexander's descendants, but I'd like to learn more. If you'd like, you're welcome to join the list.
