Hi Nigel
If he is a Non Commemorated soldier and you need any advice( when you find him!) let me know ive just successfully had a lad added to CWGC Debt of Honour i suspect he lies in an unmarked grave in East Ardsley after dying of TB in Carr Gate hospital in 1918 after discharge.Thankfully i had a partial record survive and hes on my local war memorial and the Death Cert was useful as it tied in with cause of discharge.
Maybe a case of viewing all George Hands Medal Index Cards and seeing if any are discharged then follow those up
Also try Yorkshire Indexers if you suspect a Leeds Connection.
Could he be listed as George Hamilton?
Good luck
Ady
