macias and salas

I have an ancestor named maria magdalena salas lozano christened on 2/jul/1787 with the parents named Josse de Santiago salas (Macias?) and francisca Lozano.
Magdalena was married to Juan antonio Casillas in Tepa on 20/may 1787

Does anybody have info on magdalenas grandparents Jose de santiago Salas was supposed to be from aguasclintes I think

My wife descends from Jose Caytano Nunez and Maria Josefa Macias from santa maria lagos lagos de moreno. Any info on them? they aare the parents of jose bacilio nunes christened 22/jun/1784
