Dear John, Nice to hear from a Nairne researcher. I do agree with most of what you wrote, however, my research points to some differences. Robert Nairne, Sr., was married to Mary Layfield, but I think she was his second wife, and not the mother of his two sons, Robert,Jr., and James Nairne. Her last name is unknown to me, but she was the widow of Samuel Layfield.The name of Robert Nairne's first wife and the mother of Robert, Jr. and James, is unknown.
