2nd Lt GHJ Daubeney was killed on 26/9/16 and his death is recorded both in the War Diary and by CWGC. His parents Henry and Eliza are described as 'late of' a Cheltenham address. However, I have been able to find no other references to the family via Ancestry etc. I did find that Daubeney is listed on Canadian memorial sites, including one for soldiers from Hanna, Alberta, so fair enough, it appears the family must have emigrated at some point and Daubeney then decided to come and fight for the British rather than the Canadian forces. However, I can't find any other references to him at all: he doesn't have a service record and there don't seem to be any London Gazette references to him. Any suggestions as to how I can find out anything at all about him or even his parents?
I should add that I am not a family member: Daubeney was a friend of the person I am researching and I am trying to work out how they met, which they evidently did before the war.
