Fantastic! Thank you, I didn't realise the picture I have for Richard born in 1894 was a WW2 uniform. Thought he looked a bit old, but this makes sense. 'Grandad Sumner' does not however, as the Auntie Louie was in fact his sister, so perhaps she had given the photograph to his grandchild? Something I can look forward to finding out!
Thank you for your great reply!
