You may have this info by now, but.... I have the information you are wanting. This William Pringle is my great-great-great grandfather. He married Jean Robson of Howspasley Farm, Roberton, on 10.3.1758. I don't have all the children you list in my info, but son Robert married Janet Burnett on 2.10.1788, and THEIR son John married one Sarah Johnstone on 12.12.1821. Their son, another John, married one of the Oliver sisters mentioned in another reply to your request and emigrated to NZ in 1857. If you want more info and have an email address I can send you a copy of my information from 1730 down to today for our particular branch of the family.
