Thank you so very much for your insight! This is exactly what I am looking for.
I hadn't given a thought to the occasion in such a way, I assumed it was of a group of servants from a stately home, however now I look closer and with your insights it could indeed be a special occasion.
The young couple you describe, I thought they may be Mother and Son? Or something along those lines?
I just wish I knew where the photograph was taken as it is indeed a very early photograph, you can tell when holding the original.
We have a feeling (but only at a glance), that the lady in the very middle wearing white with a white bonnet and holding flowers may be our ancestor - a direct descendant.
I have often thought it is bizzare the way in which one lady has her back to the camera.
Thank you again!
