Hi Myyran, the Joe Cuthbertson you mentioned was my grandfather, and Mary McGlinchey was his third wife. My father was the son of his first wife, Mary Mochan. After Mary died he married Annie O'Kane, and then Mary McGlinchey. He was abt. 66 when he married her. Altogether he had a grand total of 17 children, 8 -1st marriage, 3- 2nd, 6 -3rd. It was his son Joe (my dad's full brother) who was the janitor at the school, not Joe snr.
