Wall freed his mixed-race daughters Sara and Caroline, and sent them to Ohio to be raised in an affluent Quaker household. Wall provided financial support that included funds for his daughters' full education. An intellectual partner of Langston, Caroline had five children with him, one of whom died in childhood.
