Hello, given that the date is over 80 years ago it is not likely many people will remember.
However you never know and I wonder if you forwarded the photgraph to say THE BURY TIMES or THE ROSSENDALE FREE PRESS you may be lucky. If you  need the addresses  let me know.
They look a charming couple, and I wish you the  best of luck in finding out who they are .
