Dispensa Question - Juan de Dios Baldivia and Petronila Alba / Pedro Baldivia and Gertrudis Alba

Hello,

I have a question about dispensas. The following marriage records (link below) show the marriage of two brothers with two sisters and it mentions that they had “un parentesco de 4to grado”, but that they had been dispensados. I would like to find these dispensas to get some further info from them.

I looked at the www.guadalajaradispensas.com website and I have not been able to find these dispensas. Is there any other place to look for them?
Or is it possible that if a marriage certificate says that someone has been dispensado, maybe that does not necessarily mean that an actual separate written dispensa was always created?

Here is the link for the marriages:

I am looking for the following dispensas:
--Pedro de Baldivia married Juana Gertrudis de Alba
--Juan de Dios Baldivia married Petronila Juana de Alba

Both marriages took place on May 28, 1714 in Tepatitlan de Morelos, Jalisco. The parents of Pedro and Juan de Dios Baldivia were Juan Valdivia and Petrona Gutierrez de Hermosillo.
I am trying to find the dispensas to find out the ancestry of the Alba sisters.

Thanks,
Minerva
