Hello Nick, My name is Peter Winmill.
I was born in 1954, and also went to the Convent Prep until I was 11 (one year before you were born!!). I remember Sister Mary Brigid very well, and she seemed old when I was there, and I had 2 older brothers (10 and 11 years older) who also went there with the nasty old Sister!!
My brother Steven also went to St. Chads, but he was born in 1943.
I have lived in Canada and the US since 1975, but returned home many times.
I would love to see some pictures of the convent, as I have none, and my parents are now both deceased.
I was also born at 8 riley crescent, which was affiliated with the Sisters, the convent, and the monastery?!
