Amazing how the aging (72) grey matter clicks, with a little prompting. Minnie's brother James was THE postman at Nitshill; another salt of the earth type bloke; pipe smoker, tweed-wearer, very serious, with a great, loud voice; married a quite-the-opposite lady, Isa, a "choochter"from 'way up in the far north who was something of a religious recluse - a situation which deepened after their only son, James (who was learning to play the violin ... ouch!) was run down and killed by a car while walking with his parents between Nitshill and Darnley (no cars in those days although James had his Postie's bike with the letters basket in front). James, Isa, long gone. If of interest they lived in a post office residence entered directly from the street just off Glasgow Rd; room and kitchen; outside toilet was very dark and scary for us kids and most visitors "made-do" behind a curtain.
The nasty brother was Wullie ("shshshsh, don't answer the door; here's brother Wullie and maybe he'll go away to the pub!!" Say-tuned
