Louise W. Greer's gravesite

My Great Grandmother was from or around the Colquitt Georgia area. She is known to be full blooded Cherokee or Seminole Indian. She married my Great Grandfather, Rueben A Greer, a farmer. So far I've found that they had at least 9 children. She is buried in Cedar Grove Cemetery, Keysville, Florida. Names she could also have went by, Wesley, Lue, Ash Or Wesley Ash Lue. I'm trying to find her family to learn more about her.
