Only just come across your site, so apologies for being late to the party.
I lived in Esh and was a pupil at St Michaels Catholic school in the 70s. As such I interacted with the seminary students from Ushaw College who sometimes acted as teaching assistants. On one occasion they took us to the college to try out the pool. I was not in there for long as it was unheated and therefore absolutely bloody freezing. I'm guessing that was intentional to cool the ardour of the soon to be priests.
I had a friend whose dad worked in the grounds and therefore lived there so would often cycle to Ushaw College from Green Court to see him. We moved to a village near Barnard Castle when I was 9 so lost touch with everyone there.
