Missing years for Jalpa Inf Mat of 1844-46?

Hello,

I've gone thru the online version of Jalpa Información Matrimonial 1844-1846, but I've noticed that only banns for 1844 are given. Has anyone looked at the microfilm roll? I'm wondering if the title is wrong or if the online version is missing 1845 and 1846.

I also noticed that this book didn't include any genealogical information for the couple seeking to get married. I think it's highly unlikely that there wouldn't be any related individuals looking to get married. Were there separate books for those seeking dispensations and for vanilla marriage banns?

Thanks,
Arturo
