I am looking for information on my Great x 4 Grandfather Zachariah Sparks believed to be full blooded Cherokee. The last known research was done in 1985 and research stopped at his son Ira R. Sparks and his wife, Mahala (Haly), maiden name unknown. Ira R. was a confederate soldier in Georgia around 1863. Zachariah was possibly married to a Sallie Brown? The Region could be Tennessee, Georgia? I know later descendants settled in Sallisaw, Oklahoma and in the Bushy Mountains.
