Información matrimonial Durango

Hello everyone, I’m researching an ancestor who married in the city of Durango in 1836, and I’m trying to locate his información matrimonial. However, FamilySearch doesn’t seem to have informaciones matrimoniales for Durango, which is surprising given how complete their collections are for many other regions of Mexico. I also checked the catalogue of the Archivo Diocesano de Durango, using the “Guide to the Microfilm Collection of the Archivos Históricos del Arzobispado de Durango” by Rick Hendriks (May 2005), some informaciones matrimoniales do exist in the archive, but many seem to be missing from the catalogue. Does anyone know whether a more updated or complete catalogue of the diocesan archives exists? Or is it possible that many informaciones matrimoniales simply no longer survive? Any guidance would be greatly appreciated.
