Brick wall in Jalpa

Hello Group,
I'm been researching the Gonzalez line and I have hit a wall in Jalpa. I am stuck in my inability to find information for Jose Maria Gonzalez who married Julia Casillas. I have found two of his three of his children, Simon, Maria, and Lucas. Lucas is my direct descendant. Based on a marriage bann and marriage for Simon in Teul in 1865, I suspect that Jose Maria married Julia around 1830 (Simon was 35 at his marriage and was from Jalpa). Maria's wedding in 1869 took place in El Plateado (no age given for her--her husband was about 26) and she was from La Villita (between Jalpa and Huanusco). However, I've looked at the Jalpa weddings for 1827-1838 and the Tabasco film for this time period, and I didn't find Jose Maria's or Julia's wedding.

I also looked at Tabasco's bautismos for 1826-1838 and haven't found any baptisms for Simon his brothers and sisters. I've already ordered the film for the next decade to see if I can find Lucas' or Maria's (or other's) baptism record. But so far, I haven't found ANY baptisms for Jalpa in the Tabasco records.

I'm wondering where else I may find baptisms for people from Jalpa?

Also I am going to La Villita in December and was going to try to see the records of the churches in Jalpa and La Villita. Have any of you had success getting access to the books? Any suggestions for how to talk to the priests?

As a side note, I have found some interesting things about my direct ancestor's, Simon, family troubles. He married Valeriana Gonzales (no relation) in 1865, and she was supposedly a virgin "celibe", but there are two records of children born before the wedding, one of which may have been by another man. A few years later though she had several children by other men. The baptisms have the grandparents' info so i know it's the "same" Valeriana.

At first I suspected Simon might have died, but then I found that there were a few other Simon Gonzales from Teul de Gonzalez who had children from different women. Unfortunately, there was no info on the paternal grandparents or age that would help confirm whether these were the same Simons. if the are the same, this meant that Valeriana and Simon must have a very spicy relationship, one worthy of a few mariachi songs or a soap opera!
