I also bought the book "With All Arms" by Carl Duaine. there is quite a bit of info. And also the book "Texas and NorthEastern Mexico 1639-1699" by Chapa and Foster. That is a reprint of the memoriers of Juan Bautista Chapa. These are two really great books to read. As you read it you actually recognize names of people that you have in your family tree and it's like reading a family story. Fantastic. I bought them through Borderland books. Keep in touch let me know how it goes.
