I'm sure you're right, Janice, as Dad was in the Tank Corps as a non-combatant due to medical reasons and although I have found his service record, I've never found him on the Medal Rolls.
If you're going to include DAVIES as a spelling, you are left with an almost impossible task. In one year on the Electoral Rolls there are about 32 James DAVIS on the Birmingham Electoral Rolls, excluding at least that many again with more than one forename. Add DAVIES & multiple forenames and you would have at least 250 possibilities and no means of identifying the one you want in any one year.
Gary, am I right in presuming that he never left the UK, i.e. as far as you know he never emigrated?
