Aguascalientes, Sagrario Informacion Matrimonial 1739

I was wondering if anyone who can read Spanish help me out on something?

I am looking at the Informacion Matrimonial films and doing an extraction of my ancestors. I have come across the film 1739 at the Family Search Pilot site and what is listed are not marriages but are list of daughters and their parents....about image 15 starts with Asientos and now I'm at image 43 which appears to list daughters from Lagos. I have never seen anything like this before in all the records I've ever looked at, and it's been too numerous to count.

I hope you can help me solve this mystery.....my research colleague is out of town with no access to the internet.

Thank you
