I descend from William Laffoon (b. about 1786 d.1862) who married Martha Winn. I know William's mother was named Sally (unknown maiden name) because it is on his death certificate.
A couple of user trees have William's father as John Laffoon (dates unknown), John's father as Nathaniel Laffoon Sr. b. 1720.
I see Nathaniel's existence is attested through a land grant but I cannot find sources for a connection between Nathaniel and John and William.
Any ideas? Thank you.
