The burial below is the best possibility I can find for the first wife of Samuel who married in Mold. 1803.
Ann Aston
Burial
28 Nov 1797
Benthall, Shropshire
Spouse Samuel Aston
The snag is there were two possible marriages and without the OPR I cannot compare his signature from the 1803 marriage.
Samuel Aston
Spouse Anne Guest
Marriage 30/10/1783 Saint Leonard, Broseley, Shropshire
Samuel Aston
Spouse Ann Gethen
Marriage 30/11/1795 Saint Leonard, Broseley, Shropshire
Samuel & Ann/e had several children in baptised in Broseley & Benthall but they are less than two miles apart. The events on family search were 1784 – 1800, so clearly one survived.
Might be worth a look, if it the one you may be interested in?
