Hi,
From my own personal experience: when I married at St.James Church Norton in 1970 I recall Canon Gleadhill asking for my father's details prior to my marriage. As I hadn't seen my father for several years I didn't even know if he was alive so the information I gave Canon Gleadhill was supposition so my marriage certificate actually states my father's name and occupation though he wasn't actually at my wedding. The marriage was witnessed by my grandfather and brother.
