Aleksandra Franciszka Lubomirska (nicknamed Rosalie by her father) (1788 in Kiev – 11 January 1865 in Warsaw) was a Polish aristocrat, artist and writer from the Lubomirski family. She was the daughter of Prince Alexander Lubomirski, Castellan of Kiev (Kijów), and Rozalia Lubomirska, née Chodkiewicz.

The child was left alone, at the mercy of the prison gaoler, who ill-treated her and almost refused her dry bread, the only food she had.
Rosalie's father was a General in the French Army but was away just then and unaware of his little girl's fate. He heard of it at last and sent for her, and the person he commissioned to fetch her arrived three days before she was to have been sent to the Foundling Hospital of Paris. She was released after the Thermidorian Reaction (9 Thermidor, Year 11, 27 July 1794) and the death of Maximilien Robespierre the following day.

Vesque's son, the lawyer and composer Johann Vesque von Püttlingen, was born in 1803 in the palace, and Alexandra held him at his christening.

RzewuskiAccording to the memoirs of Countess Varvara Golovina, the "extraordinary opening to her life seems to have been only a preparation for every virtue, and her mind is the flower of her soul." In 1805 she married the orientalist Wacław Seweryn Rzewuski (nicknamed "Emir") in Vienna, and was the mother of Stanislaw Rzewuski, a historian of philosophy, and of Leons Rzewuski.
