Hi there Jill. I'm a newbie oñ here but saw your post as I was researching a Marian Colthorpe..to take her funeral today. She was the younger sister of Edna Colthorpe your fiercesome Deputy Head..lol. Think Edna died a while ago but Marian was 97 and her younger sister Margaret is 94. They all lived together in a House on Lady Bay Rd in West Bridgford from the 1920's till 3 years ago!! Only Margaret married. Says a great deal about the kind of teachers there were in the 50's!! I had similar ones but over in North Staffordshire at a Girls Grammar School.. frightening old biddies and awful rule
