The 1898 census gives her Hocąk name as Wa-ra-char-wa-win-kaw, which is for Warečáwawįga, from warečáwa, "Twin"; -wį-, a feminine gender infix; and -ga, a definite article suffix used in personal names. She was probably not called "Twin" because she was one, but in honor of the Hero Twins of lore, who are called Warečáwa.
Near the time of her death she was living in Winnebago, Nebraska, in a traditional lodge with her grandson William jr. (1900 census)
She died on 10 Oct. 1900, not long after the census in June of that year in which see appears. (Linda W.) She therefore almost certainly died on the Winnebago Reservation in Thurston, Nebaska.
