Great Research to possible match.
By Coincidence just before Christmas I was asked to Research a Soldier Biography in WW1
I found his Marriage pre WW1
Then found his Brown Medal Index Card showing he was Discharged in 1916 with a Disability Pension Award and Silver War Badge
The Fold 3 Disability Pension gave me his Home Address to where he lived and Pension paid to.
With Free 1921 Census in the Library where I live - I searched for his Home address in Liverpool
I discovered he was not listed on 19 June 1921 at Home in Liverpool only his Wife and Kids
So I searched the Census for Him
And found him as " Patient"
Looking into the front page on that Census
He was in a Military Convalescent Hospital in Blackpool some 5 years after his Discharge here"-
