Sánchez de Mendoza

Does anyone have anyinfo on this couple, I have not been able to order it yet becuae I have 5 films already at the FHC.

Andrea Sánchez de Mendoza
Juan de Villaseñor y Orozco
Marriage: 20 Aug 1724 Jalostotitlán

I do know for a fact that Andrea is related to the same Hurtado de Mendoza. At least two daughters of the Toribio Hernández (Fernández) de Arellano and Isabel Hurtado de Mendoza, used Sánchez de Mendoza. I think Andrea last name had been passed down maternally. So her father may not even be Mendoza at all. The thing is I have not seen any Sánchez de Mendoza after 1670 or so. So it could be a grandmother of hers. I thought it died out but was wrong. Any help will be appreciated! Does anyone have this record or film on loan? -Daniel
