Actually, I was kind of looking around for songs with references to Indians when I found this song in the AP Hudson book. I had just read "The Journal of May Dodd" which is a fictional account of a white woman who goes to live and be a bride of a Cheyenne Indian brave. Evidently the Juniata is a river in Pennsylvania as you all have noted and the song's composer was inspired by the river. I'll post the info from AP Hudson when I get home later. His informant seems to have collected it in the area and brought it to Mississippi. harpy
