My grandmother (a Duggan), is telling me that her grandmother Julia Ann Soward was a full blooded native American. She was born in Loudon Tenn. in 1864 and married Wilson Marion Duggan. came anyone help me to verify this information, or point me in the direction where I could verify this. All the census records I find show her being white, but I'm being told those can be wrong a lot. Thank you in advance.
