Cherokee Indian

My birth mother's name is Judy Davis. I was told she had two daughters through another man who wasnt my father. One of the daughters was named Trianna or Teanna or something simaliar sounding to your name. Apparantly, I also have aunt named Brenda who is living in Goergia. My mother was one of many siblings, all who went into foster care when their father died. I'v been searching for my sisters for years, but without any names, dates or even the name of my birthmother's parents there isnt alot I can do. Im also about a half cherokee. It would be nice to have a family. Please reply or contact me
