I have information from earlier research done about 1953-55 that members of our families went to the High School in Donaghmore. Are there records available listing the names of the puplis attending there?
Most surviving school attendance records are held in PRONI (the public record office) in Belfast, in the SCH series of records. They are not on-line unfortunately, so you would either need to get someone to make a personal visit or you could ask PRONI to search for them (for a fee).
