I would be grateful for a tidy up of this photo please and anything else you care to do.

I am trying to work out who is who but I am hopeless with ages!
There is Joseph b 1886, Charles b 1887, William 1888, Adolphus 1896, Hector 1900, Trevor 1901,
Richard 1902 and Sylvester 1905. A couple of them seem obvious but others I don't have a clue.
I am presuming that the oldest man is the grandfather, do you think the resemblance is there? Grandfather died in 1913.
Any help would be lovely!

Thanks,
Elin
