My bad, I didn't read the next pages. Clemente de Acuna is an informant that stated that the groom and bride were actually related. I had to draw a little family tree to find the relationship between the two. The common ancestors were Pedro Cid Caldera and Maria Carrillo.
First the groom: Pedro Cid Caldera and Maria Carrillo had a daughter, whose name is unknown by the informant. This woman had a daugher named Maria Rosales, who married Jose Carlos de Godoi. They had a daughter, also named Maria Rosales, who married Martin de Arceo. This couple had a daughter, Clara de Arceo, who was the mother of the groom, Francisco Miguel Marquez.
Now the bride: Pedro Cid Caldera and Maria Carrillo had another daughter named Clara Cid Caldera. She had a son named Nicolas Caldera, who married Leonor Rodarte. This couple had a son, Nicolas Cruz Caldera, who married Barbara Casilda, and they had a daugher, the bride, Anna de Santiago Caldera.

According to this chart, http://genealogy.about.com/library/nrelationshipchart.htm
the pretensos were third cousins once removed. I hope that helps.

I just read your document and it is about the matrimonial information of Franco. Migul. Marquez, an illegitimate child of Clara de Arzeo, and Anna de Santiago Caldera, daughter of Nicolas de la Cruz Caldera and Barbara Casilda de Vlloo. I read the previous pages, and it does mention that there is no blood relationship. On the information of the groom, however, it states an impedimento because he asked the mother of the bride for her hand, not the father. That could be the reason this dispensa made it to Guadalajara for further investigation.
