I am also a member of this family. Effie was my gg grandmother. My family accounts have described her as either fully Native American or half-Indian and half-black. She is described as black in the 1880 census. She lived with R.M. Speller, a white man and the child of a large slaveowner and member of NC assembly, Thomas Speller. The 8 children in the household in 1880 are described as "mulatto." Thomas's brother C.B. Speller served as a lieutenant in the Confederate Army, and lived next door, according to the 1880 census, with his all-white family. I would love more information about Effie (called Affie and Anaffatt in my family accounts) and Robert M. Speller and their immediate families.
