I know it's been a while but maybe somebody could help me. I am doing some research for my cousin and her great-grandmother was Mary Elizabeth(Lizzie) Roberts married to Frederick Rich Eaton. Her mother did some research well over 25 years ago and the family lore was that Lizzie Eaton visited her mom on an Indian reservation in Jonesboro Maine. I see from the census that this family is listed as black. Does anyone know if they were Native American or perhaps mixed?
