i don’t have any Welsh stories, except that my aunt’s family moved to Wales, weren’t on the phone, (neither were we at the time) and the way to contact them in an emergency was through ‘Grey the Gas.’
However, a slightly related address story. A good friend has one sibling, a brother who moved to Australia a long time ago: years of being on Mumsnet now make me think he was the Golden Child. They kept in touch via occasional airmail letters but their parents never saw him or his family again, their mother being unable to fly for medical reasons.
Unlike him she didn’t go to university straight from school but later gained academic qualifications part-time and eventually was accepted for a Master’s at Cambridge.
She mentioned this in a letter, adding which college she was going to, and received a postcard at college from her brother addressed to Friend’s Name, Trinity Hall College, Cambridge, UK. He’d never sent her a postcard anywhere before and clearly didn’t believe she’d managed to ‘get to’ Cambridge.
(Trinity Hall and Trinity College are different colleges, both part of Cambridge University. There is no Trinity Hall College afaik, although I have found erroneous references online, such as this Lonely Planet one which is about Trinity Hall but is illustrated by a picture of Trinity College.)
