The Good Shepherd Home seems a good lead as my great grandfather, Peter Doyle, always said that the orphanage he had been in had burnt down and the records destroyed. He said that was why he never knew his birth date - which I have since found. He ran away when he thought he was 13 - about 1883. We always thought it was an orphanage in Wexford though.
I will write to the address in Waterford and also try the dept. of education.
