Hi David I have a marriage Margaret Morrell (Samuel Morrell & Margaret Torrens) to William McKay (Neil & Jane McKay- this is the Neil who was sexton Kilrea) at Garvagh C of I 19/01/1865. Their son also William immigrated to Queensland Australia. I have further info on him if he fits into your lists. My interest is McKays rather than Morrells. Pauline O'Keeffe
