John Patton - Susannah Broyles
Dr. Kelley did the important early work on this line.If I were you I would find his manuscripts and find out where he got Margaret's birth date. It woule be from a family Bible or maybe a tombstone.I think if I recall correctly that he gave them to the Presbyterian Hist Soc. in Montreat NC.This is not the exact name of the archive, I am writing from memory.
I have not published your line.I have your line in section  of my compendium. If you wish I can send you what I have by email.
