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

It’s something I can look into, so thank you.
From a Quick look the regimental numbers had just been assigned in alphabetical order based on surname.
However, it could be that there is a link between the Jones’s.
Something for me to look into, as I’ve nothing better to go on!
Thanks.
