Hello,
I realize that this post is 15 years old, but if you are still wondering about the tall tales of our indian heritage, I am afraid they seem to be farfetched. I am a Great-Grandaughter of Henry Keffer and Nellie Mae Archer. I recently had my DNA traced along with my mothers who would be grandaughter of the Keffers. Both of our samples came back as having no trace of indian heritage whatsoever. I am not sure where this legend originated. I think sometimes when someone was born with dark skin, eyes and hair perhaps it was attributed to some mystery indian bloodline without any proof to substantiate. Perhaps the suggestion was born from a time when they lived in a town called "Running Waters, Sioux Nebraska"? I encourage you to get the DNA test yourself to be certain, but as far as I am concerned, we have no ties to the American Indians. And it seems that this was confirmed on every record I have found for Nellie Mae and Henry Keffer where they always marked "white" when asked for race.
