High Quality Content by WIKIPEDIA articles! Uncle Wallace Willis (sometimes Wallis Willis) was a Choctaw freedman living in the Indian Territory. His dates are unclear: perhaps 1820 to 1880. He is credited with composing (probably before 1860) several Negro spirituals. Willis received his name from his owner, Britt Willis, probably in Mississippi, the ancestral home of the Choctaws. He died, probably in what is now Atoka County, Oklahoma, as his unmarked grave is located there.
