Thanks for your response ... this is odd - I attach the ID card of my cousin - Janet Cuthbertson - aged 17 - but living in the city of Glasgow, Lanarkshire, Scotland in 1946 instead of the town of Wishaw, Lanarkshire, Scotland where she was born in 1929.
There MUST be a register of these codes somewhere .... my beautiful and very glamorous cousin was known as Jenny, and was NOT the kind of girl to have been in service ... I wonder if she was pregnant and shipped to Glasgow for the birth?
Sadly, she is dead now, but if there's an unknown child out there, I would like to know ... the address on the card is rather grand, and as yet I have not knocked on the door, but if all else fails ... It's just a few miles from where I live.
I have searched the Scottish birth records but nothing leaps out at me - was this address just a grand house or some kind of nursing home?
Again - what is this class code, and what are the numbers top left of the card?
Any help much appreciated .... thanks.
