Welcome from me too

The 1920 marriage certificate sounds as though it is the earliest document you have of Albert so, as Carole's questions indicate, the detailed information on there is key to helping us help you.
So some more questions from me:
Where in London did the marriage take place
Was Albert shown as having any other given names
What was Albert's address at the time of marriage
Who were the witnesses?
Also - do you know when and where he died, and what age/birthdate was recorded for him then?
