These sort of events usually happen at times of urgency, and many people who got married in that era didn't even have the money or time for photographs or 'proper' weddings. Even the wedding rings might have been obtained from the local Woolies store, perhaps to be changed in better times.
On matter occasions now, I have often wondered about my 'extended' family, but when everyone was around I never gave it a thought to ask. Whether this was upbringing (you never asked)or perhaps non-concern at the time, I really do not know. What I do know, is that I wished I had been more inquisitive and perhaps hoarder of previous relics. Because some items can never be replaced.
