Wish I could help more but you have stumbled into the twilight zone of my research.
I cannot speak of your Elizabeth NOBLETT as I was not aware of her before your message. Don't recall a SKAGGS / NOBLETT connection in KY but will check some of my material which is in hard copy.
Adeline NOBLETT was the daughter [probably] of William NOBLETT and possibly his wife named Margaret BARR [daughter, maybe, of Caleb BARR]. It is also possible she is the daughter of William's son Thomas NOBLETT. As you can see there are a considerable number of questions for which I have no answers, only clues. The records are sparse and matters are further confused by the fact that William and Thomas both died intestate within a year or so of each other leaving minor children.
What I can say about this particular group of NOBLETTs is that they were in Rhea Co. TN for nearly 30 years before moving to MO [1808 - till after 1830]. My best guess is that William was born in NC and his parents in PA.
