One picture can tell more than many words like this beautiful family-tree of "Mona Lisa" or Isabella of Aragon (1470-1524), the Duchess of Milan and Bari, created by Chris Anthony Wills. By the way, we are now living in a time, in which it is possible to check whether Maria of Aragon (1503-1568) and Antonio of Aragon (1506-1543) who were buried next to their mother Isabella are really her children or the children of Isabella’s uncle Ferdinando d'Aragon († 1542). It’s just a matter of will.
