Villalpando = Soto

I am researching my maternal 5th great grandparents, Juan Manuel de Villalpando married to Gertrudis de Soto, on 20 Feb 1757 in Teocaltiche, Jalisco, Mexico. They ahd 5 children: Maria Antonia, Maria Alvina, Jose Gregorio, Pedro Joseph, and Luciano Villalpando.

I am seeking the birth/baptism dates for Juan Manuel de Villalpando and Gertrudis de Soto.

Any help would be appreciated.
