She came of good stock. The gifted Mrs. Montague was the grand aunt of her mother. Baron Rokeby, Primate of all Ireland, and the most liberal Protestant prelate of that island, was her mother’s uncle. General William Campbell, a man deeply versed in the Oriental languages, and the companion of Malcolm in his embassy to Persia, was her mother’s brother. James Mylne, Professor of Moral Philosophy in the University of Glasgow, was her father's uncle. Her father, although scarcely twenty-nine years old at his death, had been a correspondent of Adam Smith, Dr. Cullen, and other distinguished men of science and letters both in England and Scotland. He was a member of many literary and scientific associations. The British Museum in London was indebted to his antiquarian researches for donations of rare and valuable coins and medals. He was regarded and consulted as authority in these matters by Dr. Pinkerton, and Mr. Planta, Keeper of the Medals in the British Museum, and others.
