Polly,
It looks as though you had an incredibly busy day!
Thank you so much for the look-ups. It's given me a bit more to go on, especially the fact that Edward Campbell was a widower, which until today I didn't know, and also the witnesses names. Now to look for another marriage!
I'm still wondering whether Francis was a Frances - at least I know Mary was his/ her mother, and Mary sounds a bit of a one, doesn't she? I can look to see if I can find Joseph Surfleet now. I do love a good mystery!
I'm really grateful for your help, and the time and trouble you took,
Best wishes,
Yorkslass
