Tololotlán

My great-great-great grandfather, José Lorenzo de Jesús Chavez, christened on the twentieth of August, 1809 was listed "Indio de Tolotlán" on his birth record. I would like to know what type of Indio he was, and what, if any, information is available about their culture, history, ect...

Another specific question: are there any other records available, specifically for this culture? If so, where can I access them?
Thanks for the help!
