She married Baron Charles Frédéric Siegfried d'Oberkirch.

Their grandson edited and published the Mémoires in English in 1852 and in French in 1854.

The baroness lived in and wrote about court society in her native Alsace, in Montbéliard, Stuttgart and (most importantly) in Paris and Versailles; her trips to the court of Louis XVI occurred in 1782, 1784, and 1786.

She was a childhood friend of the Grand Duchess Maria Feodorovna (Sophie Dorothea of Württemberg), later the Empress of Russia, and of Goethe.

Her writing provided insight into high society during the end of the ancien régime.
