Spivey IN Alabama 1800

Trying to find more information on Eddie Lawrence Spivey 1874-1957, my ggrandmother. She is the daughter of Nathaniel Spivey 1845-1891 and Mary Davenport 1843-1929. My mother, her granddaughter always told me she was Cherokee Native American. If anyone has any information on this or the family line I would greatly appreciate you help. Thank you.
