Kurš apprecējās ar Yolande, Duchess of Lorraine?

Yolande (2 November 1428 in Nancy – 23 March 1483 in Nancy) was Duchess of Lorraine (1473) and Bar (1480). She was the daughter of Isabella, Duchess of Lorraine, and René of Anjou (King of Naples, Duke of Anjou, Bar and Lorraine, Count of Provence). Though she was nominally in control of major territories, she ceded her power and titles to her husband and her son. In addition, her younger sister was Margaret of Anjou, Queen of England.

In the 19th century, a romanticised version of her early life was popularised by the play King René's Daughter by Henrik Hertz, in which she is portrayed as a beautiful blind princess living in an isolated garden paradise. It was later adapted to Tchaikovsky's opera Iolanta. There is no evidence that she was ever blind.

Frederick (Ferry) II of Lorraine-Vaudémont (c. 1428 – 31 August 1470) was a French nobleman. He was Count of Vaudémont and Lord of Joinville from 1458 to 1470. He is sometimes numbered Frederick V by continuity with the Dukes of Lorraine.
