Seven months later, on 18 October 1826, Louise secretly married in St. Wendel her former lover, the Baron Alexander von Hanstein (later created Count of Pölzig and Beiersdorf). In her previous marriage, she had taken great interest in the social life of the principality and was revered as its Landesmutter (literally, "mother of the region").
She soon remarried to Alexander von Hanstein, Count of Pölzig and Beiersdorf, dying in 1831 at the age of thirty. The year after her death, their father married his niece Duchess Marie of Württemberg, who was his sister Antoinette's daughter. Their stepmother was thus also their first cousin.
