En el pueblo de Nochistlan en otro dia mes año ante mi el bachiller Matheo Gomez Dho Señor Vicario parecio Matheo Ruiz de Roca vecino español vecino de este dicho pueblo el qual por su nombre propio dijo haber hecho informacion para casar con Thomasa Parada de Ulloa ya hija legitima de Ulloa marques que al presente no estando constan en su primo consanguineo en quarto grado de afinidad por la copula licita porque la dicha Thomasa Parada fue hija de Nicolas Lopez nieta de Doña Juana de Leon hija de Francisco de Leon y Juana nieta de Martin Navarro y de Doña Petronila de Moctezuma y asi vienen en quarto grado por linea recta dichos Martin Navarro y Doña Petronila de Moctezuma los quales tambien estan en el mismo quarto grado la dicha Doña Thomasa Parada de Ulloa porque el dicho Pedro de Ulloa mas que nieta de Doña Juana de Leon hija de Francisco de Leon y Juana nieta de Martin Navarro y Doña Petronila de Moctezuma fueron los padres de dicha Maria Gabay Francisca y la Gabay de quienes luego nacieron hijos descendientes segun consta de la presente causa que se trae y se declara ante los tales y aun fue como descendencia de dichos como se declara en la presente informacion

This is weaker proof than in many of the other connections, because we don't have a baptismal for Ana Francisca herself. Many skeptics say we don't have much documentation of this connection, but there is at least this–1703 marriage dispensation (written in living memory of Francisca), that clearly states she is the daughter of Petronila and Martin Navarro.
My internal skeptic tells me a document written 50 years after Ana Francisca's death–utilizing the name Montezuma–might have been done for personal gain, but I don't think that would have been done in a consanguinity dispensation, which is what this is. That is to say, because they are related, the couple normally wouldn't be allowed to marry. This document is their petition asking the Church for an exception, explaning the familial relationship. If there was no well established familial connection between the marrying couple, there'd be no reason to do that. And seeing as the church might say no (eg they can't get married), it's a risky thing to fake.
I also found another 1689 marriage dispensation that names Ana Francisca as the sister of Cristobal Navarro (believed to be Petronila and Martin Navarro's son), but I don't think that's any stronger and don't want to add any confusion, so I've left it off.
