Elkannah and Mary Ann Adams had 9 children and one of those children was Mary A. who married John Bonny. Not sure what the date of birth for Mary A. is; however her siblings dates are 1775 to 1794. It is possible that your Nathan could be the son of John. The Adams family named their children from family names and Nathan is a family name. I also have Aggy was one of their children and she married Nathan Adams. Elkannah is buried in Madison Co.Ky.Elkannah did not come to Clark County, Ky until very late in life. He died in 1805-1806 and their children would be born in VA. Could be Pittsylvania VA.
