Any Help appreciatted

Hello Everyone,

I am looking for the parents or any info on Diego Diaz Montanez de Sandi and Juana Josepha Albares Tostado, who were married Jan 13, 1737 in Nochistlan.
I found in the LDS files a Juana Maria Alvares Tostado born 1721 Jalostotitlan, parents: Lucas Alvarez Tostado and Apolonia Fernandez Cordero. But I am not certain if it is the Juana I am looking for.

Thank you.
Sofia
