Brilliant thanks everyone! I will ask the secretary about the bloodstain and blue nun tale then sounds interesting!
Let's just say that the story sent most years of the school into a frenzy. Most kids refused to go to the loo by themselves during lessons they were that scared!
The legend has it that she would wander around in the toilets of the juniors - now the library and staff loos. Not sure why a nun would hang around in loos unless she needed to spend a penny just before she died
People used to try and scare each other by doing silly things like leaving blue handprints (poster paint) on the tiles in there.
Also, the water stains around the chimney on the infants - which you can see from the juniors when you're upstairs, were supposed to look like a woman's white hair.
People would even claim they had heard the bell ring over in Flaybrick
Lodge house and blame the nun!
I wonder if there are any staff left that would remember the tale.
