I am sorry. All I have on the Ferguson family is that Bettie, daughter of Lord Ferguson, eloped with Samuel Caulfield, the groomsman abt 1785. Recently, I was told it was actually James Caulfield that she eloped with. They had daughters Jane, Mary, Bettie, Margaret and son James. I thought perhaps if the father was Lord Ferguson, there would be much info online but I have found none. Daughter Bettie married a Mr. Hamilton, probably abt 1825, whose name I am guessing was John, but I have never found his first name anywhere. Hamilton children were Henry born 1829, Margaret born 1826, and Ann born abt 1832.
