Thank you all for the replies and suggestions

and comments on womens dress.
Re the photograph. As it was in my nan & g'dads album the people are likely one of their families?. My nans parents age's in 1911 was 40 and 36, my granddads 41 and 38. I think too young for the elderly couple and too old for the others. So, the two elderly people may be my nan or g'dads grandparents, but which of these possible eight families?
Lookin through my saved copies of Ancestry documents and seeing which couple's were alive in 1911, and who were about the age I think the two older people look, a possibilly is my g'dads parents. His dad was 67 and mum was 64. They had son's who were in their 20's and 30's in 1911. I don't know yet whether their son's were in the Army or not. Looks like I'll soon be renewing my Ancestry sub and will make a start with them.
It's a start, and there may be other of their g'parents who were both alive and had son's the right age and in the military, I haven't yet looked through my saved records.
The uniform jacket of the lad on the right, even though he is sitting on the arm of a chair, looks to be quite long, about the length I think mounted troops wore. Maybe he was in a horse artillery unit? I think will attempt to try and find a possible son or son in law who was in such a unit, then see if things fit.
I realise I will never be able to identify these people for certain, but it's a frustration we all have to live with
