As you will see, the marriage of George
Fisher in 1855 was to Emma
Ham, not
Binding. As she was a widow, one will be her maiden name and one her previous married name - I don't know which is which without checking further.
A copy of the marriage entry is attached. Note that they married in
Emmanuel Church which only 'opened for business' in 1847. Any further checking would have to be in the St John registers.
