Susan, I have some records that might indicate that a John Fullenwider, no birth date, son of Jacob Fullenwider, born 1767, grandson of Henry Fullenwider born arond 1722, might be the John you are loooking for. The date is close.
My lineage is through a Peter Fullenwider, Jacobs brother, and both were probably living in Shelby CO, KY at the time of John's birth. Hope this helps,
