Hedwig Elisabeth Amelia de Baviere Pfalz-Neuburg

She had no male heirs, so by the standards of the day she was probably seen as a failure.

Daughter 1: Maria Casimira Sobieska became a nun.

Daughter 2: Marie Charlotte Sobieska (1697-1740) married Charles Godefroid de la Tour d'Auvergne, Duc de Bouillon (1706-1771).

Harry Potter's owl was called Hedwig - is there a connection?
