According to family history, Elias was adopted by Sanders' family. I believe that he was from the Cherokee Indianss, because I believe that his name was Elias Plumer (Plummer) and when I was in Cherokee, North Carolina a couple of weeks ago, there were alot of "Plummers" (Plumers) as their last name, but this just a guess??
A number of people have published information on the Internet stating Elias was an "Indian from the Plumer or Plummer Indian Tribe". Others have said that it was his wife Mary Carter that was Indian. The source of the Plumer/Plummer Indian myth probably originated from the book "The History Of Hart County Georgia" by John William Baker (see excerpt). In this book Baker states that Elias Sanders (Jr.) father was "thought to be British, his mother, an Indian woman from the Plumer Tribe". This error has caused widespread errors and misinformation on Genealogy websites.
What is known Elias Sanders Sr. Indian heritage comes from documentation that was part of a Federal Court case. In 1902 the Cherokee Nation filed suit against the United States Government concerning grievances arising out of treaties. On May 18, 1905, the court decided in favor of the
Eastern Cherokees and more than $1 million was appropriated by Congress for use in payment of these claims. Guion Miller was appointed as a Special commissioner of the Court of Claims.
