Sure, I'm interested in anything you may have found on the James Sayles of Kentucky & Illinois, especially including confirmation that he's the same person as James Sale / Sayle / Sales / Sayles of Wilkes County.
About the last firm trace I have of James (son of Wm & Ann) is the 1810 census, in Wilkes.Some years ago, I looked at some censuses and county records, and corresponded with a couple of people (and you and I exchanged at least a letter or two) about the James Sayles who appears in southern Illinois early in the 19th century.Without taking the time to dig through my Sale/Sayles papers to confirm, it seems that at the end of that overview I was satisfied that he's identical with the James who left Wilkes County shortly after 1810.
I honestly don't remember the Kentucky part, but that would certainly be of interest.There's much that I would like to fill in relating to the hows and whys of these people's westward movement.This Leonard Sale in Logan and maybe Todd Counties is a big question mark, which I will address in a separate response so as not to throw too many different subjects into this one post.
Back in Wilkes County, James Sale was also enumerated in the 26-45 bracket that same year.His first tax in Wilkes County was in 1792.Based on these facts, and other aspects of the family, I have posited a birth year of around 1769 or 1770 for him.So it's not very likely that he would have had a son by 1784.
Robert Sale (son of William (1720-1788) was even younger, and the families of William & Ann Sale's oldest sons Cornelius and Leonard Sale are known from their wills.So if Leonard Sale of Logan/Todd Counties was a grandson of William and Ann Sale (which I am not treating as a given; only for purposes of analysis), he must have come through the middle sons:William, Thomas or John.John was still single as of his first tax in 1782, AND he named no son Leonard in his will, so I eliminate him from consideration.That leaves wanderers William Sale Jr. (really, we'd say, William Sale III) and Thomas.
