^The singer's personal data comply with those stated by the Dictionnaire de l’Opéra de Paris sous l’Ancien Régime (article: "Gavaudan (la cadette), Marie-Françoise-Adélaïde", by France Marchal-Ninosque, p. 804). The website Almanacco di Gherardo Casaglia attributes to her instead the names of Alexandrine-Adelaïde Gavaudan-Ducamel and Alexandrine-Adelaïde Gavaudan-Joinville, but both obviously derive from an erroneous mix between the singer herself and two contemporary colleagues: her sister-in-law Alexandrine-Marie-Agathe Gavaudan-Ducamel, soprano of the Opéra-Comique, and Suzanne Joinville (1758–1804), soprano of the Paris Opéra who had debuted alongside Adélaïde's elder sister Anne-Marie-Jeanne [fr].
