Help reading document. Phelipe Mexia and Ma de la Rosa Sandoval marriage Nochistlan

Hi,
I am having trouble following who is whose parent, grandparent, and great grandparent.
I got so far that Bernardino Mexia and Maria de Luna are Phelipe's parents.
But I can't figure out how Melchor de Moscoso y Sandoval, Mariana de Moscoso de Sandoval, and Magdalena de Islas are related.
