I am also a descendant of Leonard Scott b.1769 who married Nancy Butts Martin. I've got a pretty clear picture of my Scott convoluted tree back to Mr. Leonard. It is a puzzle to me prior to him. There are 3 or 4 theories out there but I haven't seen clear proof for any of them.
If you untangle the Leonard Knot, I would very much appreciate seeing your results.
Michael, so Doyle, so John Henry, so Milton, so Leonard, so Jesse, so Leonard b. 1769
