Hi Glynnis
I lived in Ferns until about 10 years ago and there was a James Canavan(Jimmie) Effernogue, Ferns Enniscorthy Co Wexford.
He was a blacksmith/farrier and was an elderly man then, Im not sure if he is dead or alive at present. He had a wife but they had no children.
Hope this is of some help, the above is the full postal address
