Was Leonor Cortez Moctezuma married first with CONQUISTADOR CRISTOBAL DE VALDERRAMA and then with TOLOSA?

Hi,

I'm tracing the line of Leonor Cortez Moctezuma, the daughter that was never recognized by his mother Isabel Moctezuma. I have found some records about she was married with Juan de Tolosa, but in others mention that she was married first with Cristóbal de Valderrama, infact the line that goes to Petronila de Moctezuma comes from this one.

Juan de Altamirano (his descendants become the counts of Santiago Calimaya) took care of Leonor Cortez.

I'd like to know if this Leonor Cortez married with Cristóbal de Valderrama is the same that later married with Tolosa. You can check this link:

Please don't forget that there was a Leonor Moctezuma (half sister of Isabel).

Does anyone has records about this subject? I mean, records that could prove that the investigation is 100% accurate?

Thank you
Alfonso
