CUSANCE, Béatrix-Marie-Françoise de , best known as Duchess of Lorraine (born Belvoir, Franche-Comté 27-12-1614 – d. Besançon 5-6-1663), known for her friendship and correspondence with Constantijn Huygens. Daughter of Claude-François de Cusance (1590-1627), officer in the Spanish service, and Ernestine van Withem (1592-1642). Béatrix de Cusance married (1) Léopold-Eugène Perrenot de Granvelle (1615-1637) on 6-3-1635 in Brussels ; (2) on 2-4-1637 in Besançon with Charles IV de Vaudémont (1604-1675), Duke of Lorraine. From marriage (1) 1 daughter was born, from (2) 1 daughter and 2 sons.
In 1634, Béatrix de Cusance had a love affair with Duke Charles IV of Lorraine, an army commander in Spanish service whose troops were notorious for their looting. When Karel courted Béatrix, he was already a married man – his legal wife was Nicole of Lorraine, a first cousin. To avoid disgrace, Béatrix's mother quickly married her to Léopold-Eugène Perrenot de Granvelle, Prince of Cantecroix. From this marriage a girl was born on January 15, 1636, who only lived a few months. A year later, on February 6, 1637, Léopold-Eugène died. Only nine days later, Béatrix and Karel, still officially married, announced their intention to marry and were married on April 2, 1637. In the autumn of 1637 Béatrix had a son, François. It was unclear who the biological father was, but the duke acknowledged the child. For more than 25 years, Léopold-Eugène's mother would conduct lawsuits about this before the Council of Flanders and the Great Council of Mechelen.
