'Maria Stella, ou echange criminel d'une demoiselle du plus haut rang, contre un garcon de la condition la plus vile. A Paris et dans les departements chez les principaux libraires, 1838'.

Maria Stella was the daughter of Lorenzo Chiappini. Her first husband was Thomas Wynn, who became Baron Newborough, and after the latter's death, she married Baron Edward Ungern Sternberg, a Russian. Maria claimed to be the legitimate daughter of Louis Philippe, duke of Orleans, and to have been exchanged at birth for a male child afterwards Louis Philippe, King of France. A. Castelot in his Philippe Egalite, 1950 has finally demolished the legend. Maria's brother Antonio settled at the Cape and is the founder of the family Chiappini at the Cape.
