Can't remember if I've contacted you before. Elizabeth Kain was wife's GG Gran. Her family are still in Morecambe. Wife is descended from Amy's sister Beatrice Florence Victoria Kingston. Did a bit of work on this side of the family a few years ago and then put it down for a while. I'm off to London with work on Monday so am going to try to find some records at the Guildhall Library. John Kain (1815) was a plumber so I'm going to see if there are any apprenticeship records. I'm also going to the Registry Office to get his Death Cert, which should hopefully identify his parents.
All the best,
