Looks like this chap on ancestry has the same marriage - the one we found After first two children were born. But I wonder if he has found anything different in the years after her marriage!
by the way - Findmypast used to be 1837online. It is a pay to view site - so if you aint paid you wont view!
but it does, I believe have the Marine deaths on it. So if anyone reading this has access, we'd love you to look for a Thomas Newton dying between the 1871 census (when he was at home with his wife and two children, though he had only married her in Feb that year..) and 1873 when Mary, calling herself a widow, married hubby number 2, Charles Mumford.
Or if anyone is going to the FRC and can look in the giant Marine Deaths book there.
Thanks.
