Charlotte (not Caroline as indicated on the frame) Rougeault de La Fosse (1791-1864), called Mademoiselle Dupont, was admitted in the Comédie Française in 1812, and became sociétaire in 1815. Critics described her as "belle brune, minaudière, un peu provocante, au demeurant assez commune". She retired in 1840, and after travels to Russia and Italy, she returned to France where she took part in the "high life" of Paris until her death.
Muneret was apparently very friendly with the theatrical world; the famous actor Baptiste was the godfather of his first daughter Antoinette, and her younger sister Caroline even had Talma as godfather.
