Marriage Antonio Rodarte and Teresa Caldera

Marriage and baptism records clearly show that Teresa Caldera (1697-1731) was the daughter of Nicolas Caldera and Leonor Rodarte (daughter of Mateo Rodarte and Leonor de los Reyes). However, I am a bit confused with respect to Teresa Caldera's husband, Antonio Rodarte.

I have viewed the marriage record of Antonio and Teresa dated Oct 1723. While it states clearly that Antonio is the son of Juan Rodarte, the mothers name is difficult to read, but appears to be Ysabel. https://familysearch.org/pal:/MM9.3.1/TH-1-15088-8854-31?cc=1410092&wc=6837213

I have also located records showing that Antonio remarried following the death of Teresa. The Informacion Matrimonial completed in 1736 clearly states he is the son of Juan Rodarte and Ysabel de Avila. Included is documentation of Teresa's death confirming his eligibility to remarry and leaving no doubt as to his identity.

While I can show that Juan is the legitimate son of Mateo Rodarte and Leonor de los Reyes, I have not personally seen any conclusive documentation showing that Leonor is the daughter of Mateo Rodarte and Leonor de los Reyes. My only source has been research performed by others with no clear citations. The relationships are shown here: http://jerezzacatecas-salvador.blogspot.com/2009/02/descendientes-de-mateo-rodarte.html

Based on this, Antonio and Teresa would have been first cousins since Juan Rodarte and Leonor are brother and sister. While Antonio and Teresa could legally marry, it is my understanding that such a union would require dispensation from the church.

Just wondering if anyone can help me clarify the relationships.
