Come home, Jimmy. All is forgotten...um, forgiven.

Just thinking about my father. James Carter (nothing to do with a well known President (ret) of a certain large country).
I'll tell what I know and you can tell me if you know him. The problem is that by now he's probably dead, even if he died of old age.
What sketchy information I have comes from a now deceased aunt who lived in Meopham, Kent.
James Carter was a little younger than my mum-Hilda Arnold. Hilda was born in 1916 in Swansea, Wales. James was born in the county of Gloucester and we'll put his DOB somewhere around 1916-1922
At some point he moved to Swansea where he met my mum and they were both working at the Mackworth Hotel, Swansea. They were both wait staff.
Details are a little vague around this time but apparently they went to work at the Black Bull around Stoke in 1951/2.
My mother return to Swansea in 1952 to have me and neither of us saw dear old James again.
I did try what I could to find him in the 80's and 90's but doing this search from Canada was really frustrating and somewhat costly and I was told that my lack of deatils were a hindrance.
The thing is that I know exactly where he was working in 1952 (Mackworth Hotel) and know his full name (James Carter). If I could only get into the National Employment Insurance archive in Newcastle I could find his Social Security numbera nd it would be easy to track him.
(Sound of screeching brakes). This information is not available to the public. So unless I can find an employee willing to take a bribe, or Tom Cruise and the cast of Mission Impossible to break in, I'm not getting anywhere. If anyone has any ideas, let me know.
