Thanks for that, Wendy. I would love to find out who they were and for someone to 'own' them.
My father had a number of 'aunts and uncles' who were family friends and no relation. It was the norm to call adults close to the family aunt or uncle as it was less formal than Mr & Mrs and NOBODY EVER used christian names for adults!
War time meant people were sometimes in places they would never have been in other times, children were sent out of London to distant relatives, or complete strangers, as well as those involved in the war effort at home being sent all over the country, so it would not be unheard of for invitations to marriages, and subsequent photos, could involve people from any part of England.
