Hi margaret
Hopefully keyworth is in Nottinghamshire and not Northamptonshire as this post is in the Northamptonshire Board
l can see the marriage on 19 Feb 1760 at St Mary Magdalene in Keyworth showing her Parish as Wymeswold
and a john getting married in 1770 to a rebecca Hemsley
As far as Baptisms go there is a 05 Feb 1809 with the name of Samuel w and gives mother of Mary in the parish of Colston Bassett which is about 2 mls from Keyworth
Also a thomas on 15 Feb 1798 to Issac and mary
Hope this can be some help
Regards
