Hi
I'm probably way off with this reply (I'm not great with army stuff

) but your post intrigued me + I like a puzzle

On Edward Jones' Medal + Award Roll there is also John Jones + George Edwin Jones - the same regiment + same dates of theatres of war served.
There is a family on the 1911 census - address 69 Furley St, Peckham, Camberwell London
Head: Henry Jones 48 - Soho London
Wife: Ellen Jones 43 - Chelsea London
Son: John Jones 20 - Chelsea London
Son: Edward Jones 18 - Chelsea London
Son George Jones 12 - Peckham London
It's probably not your Edward Jones but just a coincidence that I had fun looking into

Regards
Deb
