To go back a bit, what is the connection with 'St John the Baptist Peterborough', if she was married etc in Rushden? I know P'boro is in Northants, but only technically. It was until comparatively recently the Soke of Peterborough, which was like a mini-county of its own, and it is really more like East Anglia. Within my lifetime, the C of E created a diocese of Brixworth (a very ancient church near Northampton) with its own bishop, to serve the west of the county.
