Thank you Glenn
I have recently made contact with Felix; extremely helpful.
Since early posts, I have made my way up the hills, sometimes getting bogged on which track leads to the McCaffertys; the Magills; the McAlisters; the Boormans; the Mulvennas as at the end of the track, they are certainly well known to each other.
However, by going wide, I am coming up with some answers. At least, I now can prove that my great grandmother Eliza McCafferty of Killyglen was bp 1839 Feystown RC; went to school in Mullaghsandal; worked in Mullaghsandal to 1862 (on grandfather or relatives' farms); and emigrated to Aus in 1864 with husband Joseph Peoples of Killyglen.
