Yes, I believe John Ardon and Hannah Oulton do fit into my tree. It turns out that the name is Ardon on the original certificate, but they both signed their names by mark X, and since Ardon and Ardern are pronounced the same, probably no one paid attention to the spelling. Also a search of surname Ardon turned up virtually nothing. Thanks again for everyone's helpful suggestions.
