My grandfather was full blood Cherokee, He worked as a blacksmith and farmer. He married Minnie Nichols in 1920 in Arkansas. I was told he had a former marriage. Due to his darkness he could have been mistaken as mulatto. Do you have any pictures of your William Anderson? I have one picture of my William Anderson in a Spanish American War uniform and several others of later in life. His father was Cam Anderson, born Aug 1, 1849, and his mother was Eliza Anderson, born Oct. 30, 1859. William had four brothers: Tommy, Tall, Steve, and John. He also had some sisters but I am unsure of their names or exactly how many he did have.
