Francisca de los Santos Coy

I am looking for the parents of Juana Maria Francisca de los Santos Coy b. 1692 Monterrey m. 17 Aug 1717 to Juan Antonio de la Garza de la Garza in Monterrey.

I suspect she is a 4th generation from Juan de Calis, but I cannot find a record of her parents anywhere.If you have information on her, please post as much info you have on the line back to Juan de Caliz and Catalina Gomez De Coy.

Thanks!
