However, after the death of Charles in 1718 they moved to Wissembourg where the family were subjected to cramped conditions and because of this Catherine began feeling annoyance towards her husband but in 1725 their only surviving child, Maria, married the King of France, which was massive upgrade in status.

She never fully adjusted to life in Lorraine and always longed for Poland-Lithuania but suffered from ill health, which hindered her opportunities to attend court.

In 1704, her spouse was elected King of Poland and Grand Duke of Lithuania after having been supported as a candidate by Charles XII of Sweden, who had at the time placed Poland-Lithuania under his occupation.

Between November 1704 and July 1705, Charles XII had his headquarters at Rawicz, and the royal couple held court at Rydzyna Castle nearby, where Queen-Grand Duchess Catherine hosted balls and masquerades for the Swedish power holders and welcomed the wives of the Swedish commanders stationed there, such as for example Christina Piper, who visited Carl Piper in Ravicz and were introduced at the Polish court at the same time.

[4] In 1714, Charles XII gave them permission to live in the Swedish province of Zweibrücken in Germany, where they were supported by the income of Zweibrücken: they lived there until the death of Charles XII in 1718[5] Catherine, as well as her daughter Queen Marie, maintained a political correspondence with Margareta Gyllenstierna, the spouse of Arvid Horn, with whom she had made the acquaintance during her stay in Sweden.

In 1733, Stanislaw again took the throne of Poland-Lithuania during the War of the Polish Succession, making her queen of Poland and grand duchess of Lithuania for the second time.

Catherine suffered from asthma and heart problems, which served as a reason for not attending ceremonial functions, and she was described as a bigot occupied with her "obsession" with returning to Poland-Lithuania.

[14] When his mother-in-law, the spouse of the dethroned king of Poland and grand duke of Lithuania, died in 1747, Louis XV ordered a commemorative ceremony, in her honour at Notre Dame Cathedral in Paris.
