Manuel de Villalpando and Maria Gregoria Guardado

Don Manuel de Villalpando and his wife Dona Maria Gregoria Guardado (d/o Eugenio Jose Guardadp and Maria Gertrudis Garcia) had at least 9 children from 1778 the late 1790s, of whom 8 are in the baptismal registers of Asientos, AGS. For one, Rafael, there is no baptism record, but his marriage record, and the baptism records of his children place him in this family.

I have not found a marriage record for Manuel and Gregoria.

Does anyone know who Manuel's parents are?
