I've been trying to find information about the Coca natives from Cocula Jalisco Mexico. I can only find a few paragraphs online. I want to know more about their culture and way of living. I'm a descendant from that town and have just over 100 years of family that lived there in the 1800's. Or if you can point me to a place that i can do some research, without having to fly there, as much as I would like to.
If you can read Spanish, your best bet might be Czitrom's book on the Tecuexes and Cocas. I haven't read it myself, but I have read some of Czitrom's other work on West Mexico. It should be top notch if you can find a copy. Abebooks has one, but it's $100+. Hopefully a library might be able to get a copy through inter library loan instead.
Information on Natives from West Mexico can be somewhat sparse, especially with groups who were present in the area at the time of Contact. The Mixton War, later Chichimec War, and overall Spanish colonial policies really took their toll on Native peoples, languages, and cultures in the area. Altman has a fantastic book on the Mixton War in English if you want to give that a read. She touches briefly on all the Native groups in the region, but primarily focuses on the Caxcanes as they were the primary instigators and fighters of the War.
