Her childhood was spent in Silesia. She was asked for her hand by many an aristocrat including Antonio Ferrante Gonzaga, Duke of Guastalla. She, however, rejected him due to the duke's mental illness.
Having travelled to Neuburg, her mother's birthplace, she embarked on an affair with Michał Kazimierz "Rybeńko" Radziwiłł,[2] a future Great Hetman of the Grand Duchy of Lithuania. She had wanted to marry him but her father would not allow the couple to elope. A depressed Charlotte wanted to leave the court and join a convent but Charles VI, Holy Roman Emperor (another first cousin), took it upon himself to find her a suitable husband.
At the French court, the House of La Tour d'Auvergne ranked as Foreign Princes. This entitled them to the style of Highness. As such, prior to becoming Duchess of Bouillon, Charlotte was styled as Her Highness the Princess of Turenne.
Frédéric Casimir died in Strassburg on 1 October 1723 leaving Charlotte a widow having been married for fourteen days. Seven months later, she married her dead husband's younger brother Charles Godefroy who was now prince de Turenne and heir to Bouillon. The new couple married on 2 April 1724 in Paris. The marriage produced two children; a daughter named Marie Louise (mistress of her first cousin Charles Edward Stuart, the Jacobitepretender) and a son named Godefroy who was the penultimate Duke of Bouillon.
The marriage was not happy. The couple divorced and Charlotte moved to Silesia. Moving again, this time to Żółkiew, she spent her last years trying to protect her father's estates of which she was the heiress to from 1737. At her father's death, she inherited the Duchy of Oława where she was born.[3]
Before her death, she designated her old lover, Michał Kazimierz "Rybeńko" Radziwiłł, as her heir. A part of her library was transmitted into the famous Załuski Library which was succeeded by today's National Library of Poland.
She was buried at the Church of Saint Kazimierz in Warsaw, Poland. Charlotte's heart was embalmed and placed in the parish church of Żółkiew. Her tombstone was designed in 1747 by her former lover. It displays a crack indicating the extinction of the Sobieski family of which she was the last surviving member.
Her husband outlived her, dying in 1771. Her son lived until 1792 and her daughter was executed in The Terror of the French Revolution.
