in France 1 of them is Frederick James Brittle dont know which one or who the others are. Frederick Brittle was killed on the 10/7/1916 at the battle of the Somme on his 19th birthday

This photograph came to me with some of my Grandfathers belongings His name was Samson Charles Gray. His family origionally came from Thornford in Dorset so I beleive 1 of the people in the photo was probably a Gray. But I would love to know the names of any of the people in the picture iof anybody out there knows who they were.
