The Matthew Camaish marriage was one I had in mind, the other being to Charles Kewley but I could only find one daughter for him.
To be honest I didn't follow this up as it was only an offshoot of investigating Catherine's previous marriage to Radcliffe and the possibilty that daughter Mary Radcliffe had married John Gawne.
What were the details of the daughters you found for Esther (I'm being lazy). I have Margaret 1799 and a son John 1801...does that tally with you?
