The family in question, Charles Kaighin and Mary Christian, may have children who went to America. This is what I'm trying to determine. Charles was the brother of John Kaighin, Quaker who went to New Jersey. There is a Charles Kaighin who would fit as the child of Charles Kaighin and Mary Christian found in Newport, Rhode Island, and also a William Kaighin in Gloucester, Mass.
Neither of these two fit as children of Quaker John Kaighin, yet their names were also spelt "Kaighn" as the New Jersey family. So I suspect that at least Charles and William and possibly other siblings, neices and nephews of Quaker John, found their way to America. For reference:
