Mr Kitterick wrote two letters in 1953 to the Superior of Letterfrack, in which he complained about three named Brothers in Letterfrack. He claimed that they were tyrannical and sadistic: Bros Piperel,17 Corvax18 and Perryn ... these men were a disgrace to the Christian Brothers. Piperel and Corvax were tyrants. Br Perryn who was in the cook-house and refectory took great pleasure in beating boys for no reason, he was a sadist, for beating us he used a piece of rubber motor tyre. Almost daily we were flogged by one or other of these Bros. Dozens of times I left the dining room with my hands bleeding ... On several occasions after a meal, I was taken to the pantry ... by Br Perryn. He would lock the door and make me undress he would then sit on a stool and would put me across his knee and then flog me savagely he would then pinch me until I was unconscious.
The Brothers he identified were all members of the Community in Letterfrack during his time there, although the presence of one Brother, Br Corvax, was only verified by the Congregation in 2007. Mr Kitterick made a spelling mistake in one of the names but that did not prevent easy identification of the person.
