Apologies for 1880. I did a sneak peek on my Tree and picked the wrong one. Re part or whole certificates, in the past I have been asked for zoomed in clearer to read extracts, but I appreciate full information helps with identifying more probable candidates and/or eliminating unlikelier. I also read the 12 Norfolk St and Deptford below it as one address for both - I'm always learning.
I'd still appreciate any info on Orange St & Norfolk St St Saviour as I have other relatives in Orange St, if I can date the change that might give me a few more clues
