Obviously up for a challenge, Liz

Maggott said the gent in the back was John Holland (holding a cheroot) & the portly lady seated far left was his/her 4x grandmother.
My observations: Was this a wedding? 4x great granny seems to be sporting a flower & the lady standing far right also (although it might be a bit of the background foliage

All the others look to be in their Sunday best also. Was this set -up in the churchyard as
it's an outside photograph? If the family decided to have a group photo I'm sure it would have been in a studio.
The adults all appear to be in their fifties maybe early sixties. I agree with you Liz that their is a resemblence but very markedly between the three men, brother? The older of the 2 girls (the one with her arm on the ladies knee) looks like the lady standing on the left.
We now need Maggott to come in with the vital details
