Little Indian Cemetery, Oklahoma

Nancy Bright Yeager child of John Bright and Susanna Broughton. Rumor has it that she was buried in full Indian Attire at the Little Indian Cemetery in Seminole County, Oklahoma. We have not been able to find the proof that she was an Indian. We would love to find this. The stories in the Bright family has been handed down for generations that we are Indians, but to the best of my knowledge no one has found the proof needed.
