I have actually got as far as a surname with this one: Tussa. But, if possible, I would like to get a forename and a date of birth to go with it.
Félix Trutat painted his famous Nude Girl on a Panther Skin in 1844, when he was just twenty. (An image of the painting is on his Wikipedia page. I will not post it here in full because, obviously, it involves nudity.) But who is that girl?
Madeleine Levinger published a monograph on the artist in 1932, in which I found the following passage:
Why was the original pension not renewed? Because, some claim, Trutat was joined in Paris by a model with whom he lived. This model would be none other than Mademoiselle Tussa or Tussat, daughter of the Dijon amateur bookseller whose loose morals caused a lot of talk in Dijon around 1850. The young girl, very beautiful, posed at the Beaux-Arts in the city. We thought we could identify this person in the reclining female figure of the Bacchante [another name for the painting in question] which was certainly painted in Paris, and we forged this little novel. Monsieur Clément-Janin, in Les Celebrités de la rue à Dijon tells us that he no longer has any doubts about the identity of La Femme nue [yet another name for the painting in question], and he tells us that Mademoiselle Tussa left her family around her twentieth birthday, to go to America where she never heard from her. Legend and also a family tradition claim that it was she who posed for Trutat's great composition. Nothing prevents us from assuming that, passing through Paris on her way to the United States, this young girl gave the painter a few posing sessions.
(The above is translated from the French, by Google translate, with a couple of light amendments from me. You can read the original here.)
There is a volume called Les imprimeurs et les libraires dans la Côte-d'Or, which indeed mentions a Dijonnais bookseller named Nicolas Tussa, born 24 Jul 1776, died 19 Jan 1852, the son of Esprit-Joseph Tussa. But it does not say anything about a daughter - or a son or a wife, for that matter.
If this Nicolas Tussa did have a daughter, and if she emigrated to the United States, I imagine there must be some official record of her birth, her death, her arrival in America, perhaps even a marriage? But I do not know where to start looking for such records; I very much hope that someone else does.
