Petronila de Moctezuma

Has anyone further researched Petronila and found documents on her true identity?

This is what I have been able to put together from the internet, this is a assumption of her origins.

1. Axayacatl (b. 1469; d. 1492)
Sp. UNKOWN

2. 9th Aztec Emperor Moctezuma Xocoyotzin (b. 1480; d. 1520)
Sp. Tzihuacxochitzin

3. Princess Marina Leonor Moctezuma (b. 1505; d. 1562)
Sp. Conquistador Cristóbal de Valderrama (b. 1501; d. 1562)

4. Leonor Valderrama de Moctezuma (b. 1532)
Sp. Diego Arias de Sotelo

5. Princess Petronila de Moctezuma (b. 1552)
Sp. Martín Navarro de Gabay

I would appreciate any thoughts or comments.
