Im afraid I do not remember your name but I was at St Margarets from 1953 to 59 so you would have been ahead of me. My Sister Margaret would have been there then as she is 4 years older than me. I will ask her if she remembers you. She might well be in the picture you posted.
I remember all the teachers you mention although Mt Sweet took over as headmaster. There was a reunion of the school last year. Did you go? If so you may have met my Sister there. I couldnt go as I live in Australia now.
I also remember the places in Pound Lane you mention,The smithy etc. We lived in Grange Road,
My Mother,Gwen would have known your family I should think but she died in 2005. Did you belong the scouts ?I remember they used to meet in a nissan hut behind the post office in Pound Lane until they built a new hut on the playing field over the road.
If you would like to chat about the area I would love to hear from you as I have quite a few memories of Bowers Gifford.
