Donnie, unfortunately it is as illusive as the Nar-nee proof. I have not seen any marriage certificates for either although I have been looking for years for both sources. All we have to rely on is family history at this point. I would hope others out there might be of some help. William Asbell's marriage record to Alan Van Winkle, however, is a matter of record. The DNA record speaks for itself.
I am earnestly trying to find the truth if it is out there.
