Lopez de Lizardi

I recently advanced my research considerably by going to the Salt Lake City
Library. I added Juan Delgado m. 4 Mar 1669 to Margarita Lopez de Lizardi
at the Sagrario, Aguascalientes, Aguascalientes to my database.
Unfortunately, the marriage record does not name the parents of either the
bride or the groom. I searched for the Informacion Matrimonial for this
couple, but it is missing. I've gone through the images on
pilot.familysearch twice (I know the records are out of order) and I could
not find it. Does anyone have any info on this couple? I found all the
baptismal records for 12 of their children and noticed that the padrinos
were often from the Ruiz Esparza, Tiscareño, Gabai, and Romo de Vivar
families. I am wondering how they may be connected to these families.
Another question I have is the Lopez de Lizardi surname sounds like it may
be the same as Lopez de Elizalde. Does anyone know if this is the same
surname? Thanks in advance for any help anyone can provide.
