WOW! Thanks for the reference!! I didnt quite know what to think. The Karankawa were done in so quickly that there is little information about what they were like culturally. About the only document that I know of is a study done in the late 1890s by a Harvard student who interviewed a woman who had befriended the last of the Karankawa tribes in Brazoria. Her name was Alice Oliver. I was fortunate enough to recieve a copy of that report. One of these days, I am going to make the effort to type it all up into a format readable on the Internet.
best,
