I am looking for the parents of Benjamin Johnston, born, circa 1759, location unknown. The closest lead to a parent is Arwalker Johnston, born 26 Aug 1718, Ulster plantation, Ireland. The history I have says his ancestors migrated there in the 1600's from Annandale, Dumb(f)riesshire. This was said to be a border clan originating during the 13th century whose chieftan was John. John is said to have bought land from the center of the district from the Earl of Annandale, who was also the grandfather of Robert Bruce. My question is there a record of Johnston(e)s migrating from Scotland to Ireland in the 1600's?
