Had to resort to Spanish

I've been reading stuff about Pancho Villa, and wanted to know more about Don Luis Terrazas, who was a very rich landowner in Mexico during Villa's time. The English info I found online seemed to talk about his wealthy and powerful life, but not his origins, and I really wanted to know why he was so rich. So I gave in, and did a search in Spanish and found something that will help get me started: Breve Historia de la Ganadería en Chihuahua.

I didn't want to read stuff in Spanish because I'm lazy and don't know all the words, which means I'll have to look them up, but it couldn't be avoided because English just wasn't enough. (I could get an English book, but I'm already reading other books and don't want to add a huge history to my list.)

Sort of related: what's great about the New York Times is that they post old articles that you can read for free: I found one about Luis Terrazas II's release from Pancho Villa's torturous imprisonment and escape to the US. I was going to post the article as a pdf here, but it's copyrighted, and I don't want to get in trouble with them :D
