After her marriage to Charles Walking Day, the censuses generally referred to her as "Mrs. John Wolf," while listing her as the wife of Charley. In the 1925 Indian census she is referred to as "Mrs. John Little Wolf." The name "Fanny Wolf" occurs in a number of censuses in which she is living alone. However, in the 1920 Federal census, she is called "Belle."
Her clan name was Chae-win-kho-no-kaw (1906 census), which is for Cewįxųnųga, from ce, "buffalo"; -wį, a feminine gender suffix (> cewį, female buffalo, buffalo cow"); xųnų, "little, young"; and -ga, a definite article suffix used in personal names. This is, obviously, a Buffalo Clan name.
She was married to John Little Wolf, sometimes called "John Wolf". After she was (presumably) widowed, she lived alone next to Charley Day Walker for a number of years, then married him.
