 In 1799, Marie Joséphine was asked by Louis to join him in Jelgava in Russian Courland to attend the wedding between her husband's niece Marie Thérèse, the only remaining child of Louis XVI and Marie Antoinette, to her nephew Louis-Antoine, Duke of Angoulême, at the French court-in-exile, which operated under the protection of the Russian Tsar Paul I. Louis demanded that she leave Gourbillon behind.Louis Stanislaus accused Marguerite de Gourbillon of extorting jewels and money from Marie Joséphine and of wearing her clothes, and stated that the kind of relationship she had with Marie Joséphine made her company unsuitable for the new role as queen that Marie Joséphine was expected to play in Mitau.After having written to the Tsar to ask him to intervene on Gourbillon's behalf, and having received no reply, they travelled there together.
