Welcome to Lost Wolverhampton.
I had a reason for visiting The Convent of Mercy preparatory School for some reason or other in the mid 1960’s.and I recall Sister Mary Brigid.
But even ten years previous to that through my job whilst working in the wholesale Vegetable Market, I would call at Poplar Road regularly visiting the Carmelite Monastery across the road, to deliver on my porters barrow, the veg bought for the week by the Mother Prioress who I got to know quite well.
I always remember as I knocked on the large oak door the sound of the Bell being rang inside to make the young ladies aware there was a visitor calling.
I will post your request for info regarding the Convent of Mercy on our facebook group and hope we may get other tales of this unfamiliar Catholic school.
