Hallmark,
Yes, it seems rather unusual that he is staunchly Irish language based in 1911, but not in 1901, his his surname is even spelt wrong in the 1901, strange. Poor lad, he had a lot of promise but went on the downward spiral of addiction, to an untimely death in 1914, the more i see about him, the sadder i feel.
Thanks for your attention Hallmark, I am really glad I got an answer in the end.
All the best
Pete.
