Where else to look for the marriage record of Rafael Luna and Maria del Refugio Gomez in Ahualulco de Mercardo, Jalisco

Hi, I'm new to the group and hope that someone can tell me where else to look for the marriage record of Rafael Luna and Maria del Refugio. They were supposedly married on 8 July 1839 at Ahualulco de Mercado, Jalisco, however that particular year is missing from the parish registers on FamilySearch. I checked through some years before as well as some years following that date. I also checked the Información matrimonial records twice but couldn't find anything for this couple. I'm new to research in Mexico and would appreciate any advice on where to look next.
