Hi SRBA,
I'm not sure where you would get records, but you could try The Presentation Convent in Thurles Co Tipperary, that's where the children went when Dundrum closed, I presume records would also have gone there, as i said i think that was late 1970's, I know some of the children went to local school with us but that was just day school, they returned to Dundrum every evening.
