Reading edition
[We may omit from the contest the pope, Gregory XIII, who claimed to be heir to a cardinal, and Catherine de’ Medici, who traced back to Alfonso III’s marriage to the countess of Boulogne in the thirteenth century.]
CHIEF CLAIMANTS OF THE PORTUGUESE SUCCESSION

* The first wife of Emmanuel was Isabella, eldest daughter of the Catholic sovereigns, who died in childbed, and was soon followed by her infant son. By Maria, his sister-in-law and his second queen, he had three other children, besides those enumerated in this table, but all died without issue.
† João III had also other children, but as they all died without issue and before him, they need not be enumerated.
