All this talk of Duke St, Onslow Dr and Alexandra Parade is making me homesick. I was born and raised in Provanmill, went to Whitehill School (off Duke St) and ran around Dennistoun up until I went to sea. Lived there too when I first married. My sister Anne worked in the telephone exchange you mentioned, at the top of Armadale St, my aunt Louise was a supervisor there too.
I’d be interested to hear of your background if it was, in fact, in Glasgow’s East End.
