Karen, You are so welcome. It was not my research it was a compilation and sorting of all that was out there to help define which Peyton Madison was which. It did take a considerable amt of time.
I do have a few Horton's in my fly tree but I find no Henry or Elizabeth Horton. I do have a few notes on Horton's and McFarland's that are not in my fly tree and will be glad to share those if you will email me at firstname.lastname@example.org
