Career
After the death of her mother Emilia, who resided at Prangins Castle in Switzerland, she returned in 1629 to the Netherlands to the court of her granduncle Frederick Henry, Prince of Orange, Stadtholder of the Dutch Republic and Amalie of Solms-Braunfels. She shared a room with Countess Louise Christine von Solms, Amalia"s youngest sister. When Charles II kindly declined, and the matter became public, Frederick William, Elector of Brandenburg showed interest.
Out of gratitude, Amalie arranged the marriage of the 38-year-old Mauritia Eleonora with George Frederick, Prince of Nassau-Siegen (1606 - 1674) on 4 June 1647 in "s-Gravenhage (today: The Hague).
Mauritia Eleonora and George Frederick had no children.
