William the Silent different from William III of England
Fourth marriage
William married for the fourth and final time on 12 April 1583 to Louise de Coligny, a French Huguenot and daughter of Gaspard de Coligny. She was to be the mother of Frederick Henry (1584–1647), William's fourth legitimate son and fifteenth legitimate child. This youngest of William's children, who was born only a few months before William's death, was to be the only one of his sons to bear children and carry the dynasty forward. Incidentally, Frederick Henry's only male-line grandson, William III, would become king of England, Scotland and Ireland, but he would die childless, at which point the lineage of William the Silent would end, to be succeeded by that of his brother John VI.
