     The Five Nations languages (Mohawk, Oneida, Onondaga,
     Seneca, Cayuga) were originally spoken in New York State,
     some speakers now in Quebec, Ontario, Oklahoma.  The other
     Northern languages were spoken in Ontario and Ohio around
     the Great Lakes, and Pennsylvania.  Cherokee was originally
     spoken in North Carolina and Georgia, now also in Oklahoma.


CADDOAN
     Northern: Wichita, þKitsai, Pawnee, Arikara
     Caddo

     Caddo was spoken in Arkansas, Louisiana, and east Texas;
     Wichita and Kitsai were centered in Kansas, Pawnee in
     Nebraska, Arikara in the Dakotas.  The few remaining
     speakers of these languages now live primarily in Oklahoma.


Probably Siouan, Caddoan, and Iroquoian, as well as the isolate
Yuchi, originally spoken in N. Carolina and now in Oklahoma, are
related to one another.
