After her departure from France, she and her family lived an ambulating life, travelling from one place to another. She kept in contact with Marie Antoinette through correspondence, by which her place of residence can be traced. The Polignac family travelled through Switzerland, Turin, Rome and Venice (where she attended the wedding of her son in March 1790), and from Italy to Vienna in Austria in 1791. She was reportedly present in the Austrian Netherlands during the Flight to Varennes, and in July 1791, she is noted as one of the extravagantly dressed women who attended the émigrée court of the count of Provence in Koblenz. The emigree court in Koblenz was however dissolved after the Battle of Valmy in 1792, and she returned to Austria, where she died.
