From the book on the Adams by Andrew N. Adams, he lists the parents as John Adams and Agnes Stone. I think this book was written in the very late 1800's. I do not know what documention he used though. But I really don't think it is William and Borington. I think someone just wanted to try to connect him to the lines coming down from the Kings of England.That line may be proven to be false. If you read the other postings on it. I decend through Henry's son Edward who married Lydia Penniman. Supposedly it is proven to be Lydia Penniman. But I don't know where that information came from either as some lines have her with a different last name.
