An intruder and non-citizen list is a list of people, usually white, who were living in Indian Territory. A permit to live there was required as the Indians had sovereign nations in IT before the Dawes Act. This period was from about 1835 to 1895(rouughly.) The site I found for the Creek Nation list is this: http://www.rootsweb.com/%7Eitcreek/records2.htm I hope this helps. Cindy
