While they were in London, a former French officer whose father had served under Napoleon I took pity on the family and made arrangements for Roland to return to France and attend a military school.

In the art school where she studied, she befriended the prosperous Monegasque heiress, Marie-Félix Blanc.

This greatly benefited the family's financial situation as Marie and her brother each gave Jeanne a million francs, after which she received many proposals,[5] but her family encouraged her to marry for love.She married Christian de Villeneuve-Escacalpon, the deputy of Corsica[6] on 21 March 1882.

On that occasion she wore a white dress trimmed with water-lilies, with a tremendously long train, and no jewelry whatsoever.

"[11] On 21 November 1907, Jeanne served as a witness for the marriage of her niece Princess Marie Bonaparte to Prince George of Greece and Denmark.
