Thanks, it is a mystery.
I have checked and not found Ann at all - I have managed to trace what happened to all her brothers and sisters (her sister Catherine Payne is my Gt Gt Grandmother), it is just Ann I can't locate.
Interesting that Eliza Paynes son (Anns sister), Robert Dimmer, married into the Spanswick family in Marylebone in 1876, especially when I would have thought it was an unusual name.
I am hoping at some point to get a copy of the marriage for John Pain and Mary Ann Wait so I can taken that further as they were my Gt Gt Gt Grandparents.
Kind regards
