Hi, Scott. I, too have no birthdates for the John Adams who supposedly married Elizebeth Johns. His date of death was l75l according to my info.James Adams,his ggggrandson, was my ggrandfather. His father's name was Moza(Moses)Adams. The first John Addams came to Va. in l674. He married Kathrine, according to the records I have. It would be very interesting to find out if anyone has traced any relation between these Adamses and the family of Pres. John Quincy Adams.My grandfather was a John Quincy and my father was J.Q.If anyone knows anything, e-mail me.
