During her adult life, Willis worked alongside her father, Wallace. The Willis family was periodically hired out by their owner, Britt Willis, to Spencer Academy in
Spencerville, Oklahoma, a school for Choctaw boys established around 1845. While working at the school, Willis and her father became favorites among the students due to the spirituals they performed during their evening work sessions. Their musical contributions came to the attention of reverend Alexander Reid, the school's superintendent starting in 1849. Reid documented several of their songs and introduced them to the broader public. Among the most notable spirituals were "
Swing Low, Sweet Chariot," "
Steal Away to Jesus," and "Roll, Jordan, Roll." In 1871, reverend Reid shared these songs with the
Fisk Jubilee Singers. The Jubilee Singers incorporated the Willis' compositions into their performances, which were heard throughout the United States and Europe. == Personal life ==
