I have only found one Charles in London who is a policeman but his wife, Mary Ann, is too old to be yours.
What were the fathers occupations and also Charles, the bridgrooms occupation.
I was going to ask this, too. It does help the people who offer to do lookups if you can give as much information as you have about the people you're looking for. It can narrow the search down and saves time and helps us to eliminate people. All sorts of things can help - for instance, knowing who the witnesses were on a marriage certificate can sometimes provide a link to other family members.
So give us everything else that's on the certificate and we'll try to find this elusive couple!
