In the Winnebago tribe book from Paul radin. I found this little footnote when I was trying to locate some Grizzly bear songs he had shared. On pg.64 you will find at the bottom where Paul Radin says that John Harrisons grandfather was a Dakota Indian. This is because of the account he gave of a buffalo hunt also on pg 64. Paul Radin also goes to say that John Harrison was a “exceedingly Unreliable source.” I feel Paul Radin felt this way because unlike the other informants he wasn’t as willing to pass on sacred information like the others.
