Her mother remarried in 1811 to Count Nicolas Khitrovo, Russian special envoy to the Grand Duchy of Tuscany.

On 3 June 1821 she married Count Charles-Louis de Ficquelmont, Austrian Ambassador before the Habsbourgs-Tuscany, who was 27 years her senior.

Back in Naples in 1825, Dolly gave birth to her only daughter, Elisabeth-Alexandrine-Marie-Theresa de Ficquelmont, Princess Clary und Aldringen by marriage.

The Countess, who was at their Venice's Palace at the time,[4] was arrested twice by the Venetian guarda civil and finally had to leave the city on board an English ship with her daughter, son-in-law and grandchildren.

The family eventually returned to Venice after the Revolution ended and Count de Ficquelmont died in their Venetian Palace in 1857.

Countess Dolly de Ficquelmont is buried in Princess Clary und Aldringen's family chapel in Dubí, near Teplice.
