“ The 7th duke was betrothed in 1565 to Ana de Silva y Mendoza, who was then four years of age, the daughter of the prince of Eboli. In 1572 when the duchess was a little more than ten years of age, the pope granted a dispensation for the consummation of the marriage. The scandal of the time, for which there appears to be no foundation, accused Philip II. of a love intrigue with the princess of Eboli. The unvarying and unmerited favour he showed the duke has been accounted for on the ground that he took a paternal interest in the duchess. ”
