[7] Following the outset of the French Revolution, Aglaé and her family fled to Edinburgh, Scotland, where they lived at the Palace of Holyroodhouse.

[9] In 1804, at the age of 17, a year after her mother's death, Aglaé married Major General Alexander Lvovich Davydov at Petersburg, Russia.

[1] The union resulted in the birth of 4 children; Ekaterina (1805–1882), Yuliania (born and died 1807), Elizaveta (1810–1882), and Vladimir (1816–1886).

She remarried in 1835 to Horace François Bastien Sébastiani de La Porta; however the marriage remained childless.
