I have found a very interesting site for anyone doing American Indian 
research.  The site belongs to Rare Book Reprints (I have no connection or 
interest in this site.)  I connected to it from a link on another list I 
belong to.  

The site is http://members.aol.com/rar
ebk.  Once there, click on "Book Lists."  There you will see a list of 
books, including many on the American Indian tribes.  Included in many of the 
book reviews are on-line surname lists.  Of particular interest to me was the 
"Cherokee Genealogial Tutorial."  It's on a clickable link and has valuable 
research information.  

Overall, this site has a wealth of information on-line, without having to 
order any of the books!

Happy hunting!
