Qu'est-ce que c'est un troisième degré de parenté?

Question

Jean Baptiste Renauld (Renauld-12) and Marie Elizabeth Guitard (Guitard-18) obtained a dispensation for a "troisième degré de parenté" at their marriage 13 Jan 1800. This appears to be distinct from an "affinité" and is transcribed in Lafrance as "consanguinité". I cannot find a link between the spouses, they have no common ancestor. Does anyone know of a different meaning of parenté than consanguinité or can anyone find an error in their tree?

Thank you, Mama Kiki

The French Wikipedia has an article on parenté, which states in part:

La parenté est une relation sociale privilégiée, consanguine ou non, fondée sur l'existence, réelle ou supposée, d'une filiation commune, d'une alliance ou sur une adoption. Selon les sociétés, elle est le fondement de droits et d'obligations particulières. Il existe un système de notation de la parenté.

Dans le cas des parentés d'alliance, on parle souvent d'affinité, dans celui des parentés d'adoption, d'affiliation.

Also, their family trees, as posted on WikiTree, are missing ancestors that could account for The 3rd degree consanguinity. So, on what I can see, based on a very quick look, there is no error.

Thank you for the information. I worded my question poorly, sorry. Lafrance transcribes parenté as consanguinité in this marriage record. I find no common ancestors for this couple but the bride’s first husband and second husband are second cousins. I am looking for another Wikitreer to support that Lafrance is in error that there is no error in the bride or groom’s trees and that they have no common ancestor. Otherwise said in this case parenté is not consanguinité and the dispensation was for the relationship between the bride’s two husbands.

Thank you, Mama Kiki

The logic is that a married couple are then united into a single person, hence the affinity between them, since she was married to her second husband's cousin.
