Charles was born about 1858. This date is relatively certain, since it is confirmed in numerous censuses. He is the son of Unknown Walking Day.
The name "Walking Day" would translate an original Hocąk name, Hąbᵋmąnįga, from hąp (> hąbᵋ-), "day"; mąnį, "to walk"; -ga, a definite article suffix used in personal names. A simplified version of this name, Hąpmaniga, is an attested Bear Clan name, "Walks in the Day." (Dorsey) However, a similar name exists in the Eagle Clan.
He is presented as John Baptiste's uncle in the 1900 Federal census. Given that John's grandfather was James Baptiste, if Walking Day had been his son, he would have carried that surname. It is also true that the Hocągara are particularly devoted to their mother's brothers, so we would expect that on being orphaned, a child would live with his maternal uncle. So Charles was the brother of Blue Back Woman, the mother of John and Jerome Baptiste.
The 1900 census shows that he was married to an older woman, born in 1848, with the Hocąk name, Ho-ra-hau-me-nuk-kaw, which is for Hora-hamįnąka, "Riding the Fish," probably a Fish Clan name. She does not appear in the 1906 census, which shows Walking Day living alone. Charley married Blue Back Woman, the widow of John Little Wolf (usually called "John Wolf"). As a widow, she had lived next door to Charley for a number of years before they married ca. 1913.
The 1925 census death list records that Charles Walking Day died on 30 Aug 1925, probably at Winnebago, Thurston County, Nebraska.
