I am trying to trace my family lineage. I stumbled across the name Chief Narcisse Isadore of the Kootenai Tribe and I have reason to believe that he may be related to my great-grandmother Mary Isadore. Since reading your post I have been trying to find more info on the Kootenai Tribe. I've been somewhat unsuccessful. The man you are seeking and my great-grandmother might have been related. Please contact me as soon as possible. We might be able to help each other. Thank you
