I have not been successful in locating any information about the Patrons outside of what I have found in their records. They have been around the Nueva Galacia area since the 1640's and it appears they were in Guanajuato and possibly Mexico City. They were not mentioned in Diccionario Biografico de Antiguos Pobladores de San Luis Potosi by Rafael Morales Bocardo or any other record I know how to locate. Although, I did see on Wikitree Danny Alonso having some connection with the Padons. I have included those connections for him.

Where would I look for their possible Testaments?
