Leonor Gonzalez

Is the Leonor Gonzalez who is the mother of Felipe Nunez de Miranda the same Leonor Gonzalez who is the mother of Cristobal Vasquez de Mercado? If the same, than she is the widow of both Sebastian Vasquez de Mercado and Pedro Nunez.

Felipe Nunez de Miranda, from the city of Zacatecas, married Mariana de Sandoval on 26 Oct 1665 in Nochistlan.

Cristobal Vasquez de Mercado came to Nochistlan from the city of Zacatecas about 9 years* prior to his marriage to Petrona de Moscoso y Sandoval on 27 May 1675.
*If I read it right. My reading Spanish is only so-so.

I only have a few chapters of "Genealogía de Nochistlán antiguo reino de la Nueva Galicia en el siglo XVII según sus archivos parroquiales", so I don't know if it says anything about it.
