Pedro, Marshal of Navarre

Pedro, his son with Juana de Peralta, succeeded him in the position, but the marshal fell dead at Pamplona in obscure circumstances at the hands of the Beaumont party (1471).

Pedro's niece Ana de Mauleon y Navarra married the noble lord Don Juan Vélaz de Medrano y Echauz, lord of Igúzquiza, Learza and Agos, major knight of King John III of Navarre, alcaide of the Castle of Del Castillo, Monjardin and Santacara during the Spanish invasion of Navarre.

[4] On 29 May 1518, while prisoner at the Castle of Atienza (Castile), he was offered the apologies of the emperor Charles V should he pledge loyalty to him, in face of which he replied as follows: With all humility once again I entreat his Majesty to prove with me the magnificence that could be expected from such immense Majesty, by giving my full freedom back, as well as permission to go and provide service to whom I am obliged.

The loyalty, the cleanness His Highness wishes and requires from his servers, I will be able to entrust to those of my kind, so that I become captive and slave at their service.While in prison at Simancas (Castile), the marshal was deprived by the governor of his long-time (23 years) trusted servant, Felipe de Vergara, who was transferred to Valladolid.

His death remained shrouded in obscurity, no official announcement was made by the Imperial authorities until 9 February 1523, when the viceroy, acting at the behest of Emperor Charles V, decreed the confiscation of all the marshal's holdings.
