Hello, Alison,
You mention you have a lot of Forces info on this chap. Had he been a member of any of the armed forces for any length of time. ? If he had been discharged after a career in the forces he would most certainly have received a pension, the Army pensions were paid thro' the Royal Hospital, Chelsea & Navy Pensions were paid thro' Greenwich, but all the pension records can be found at the main Public Record Office at Kew.
If he had been in the Army, do you know his Regiment? If so, try Google, entering the name of the regiment & trying to find a link to a museum or archive, there may have been service medals awarded, these would be on record at Kew.
If he had been in the Navy his records may show the name of a ship, try asking Kew about this. The same would apply if he had been in the Air force.
Why not post his name & date of birth, & any forces info & let some of us have a try ? We might find something or nothng.
We are here to help.
Meliora
