Hi Sue,
It looks as though our postings have crossed each other here.

I saw the entry on IGI for the 1833 marriage in Ramsey for her as "Crowe", but have not looked beyond that.
The family have Rebecca's previous history as having been married to Corkill and they well may have the certificates etc. for all of that.
The whole thing looks complicated (to me) - both William and Rebecca having been married before - with quite a selection of children
between them.

I will pass on your reply here, to the family.

Thankyou,
MC
