Notsoastute: You would be on more solid ground if you claimed the Sans Arc did not use bows (thus the name). There are also Hunkpapa (Sitting Bull’s clan), and the other five, which I would have to look up as recalling names goes well before the stereotypical short-term memory after 80. Some divide the Lakota and Dakota, but my Lakota colleague did not make that distinction. Since he is Lakota by ethnos, primary language, religion, and culture, I will rely on his opinion. Lakota (or Dakota, if you insist on dialect differences) is what they did (and some still do) call themselves, Sioux (throat slitters) is an enemy term, from those whose guns forced them onto the plains before they got the horse.
