Thanks Peter,
sounds like you might be a useful man to know

.
As far as I can find out, Elizabeth Jones married Joseph Ames in 1869. His name is spelt 'Jospeh' in the BMD marriage listing. Elizabeth Jones had been married before, and her maiden name was Williams. I haven't even tried to find her first marriage to be honest, due to the volume of Williams and Jones I would have to wade through

.
In fact I have just bitten the bullet and had a look - I have found her, married to Thomas Jones, with children Leah, Robert, Hannah and Mary Ann - on the 1861 census.
I don't really understand why then, on the 1871 census, she was living with her mother, Elizabeth Williams and her two children, Hannah and Mary Ann - as at that point she should have been married? It looks like I have got confused somewhere along the line....
I have hit a brick wall with my g-grandad George Bain(es) as I can't even locate his birth certificate. My only way forward now is to try and find a descendant of Elizabeth Ames/Jones/Williams or Joseph Ames, as they brought George up from a small boy.
It goes without saying that any help or advice you can give would be very much appreciated.
Thanks again.
Lisa.
