Jo is a field hand enslaved by Mr. and Mrs. Henry. He is an older man, prone to bouts of drunkenness, and very superstitious. When the enslaved workers on the Henry estate begin to tell stories about a ghostly visitor (which turns out to be just Charlotte’s husband, William), Jo becomes very fearful. Hannah has at least one conversation with Jo on the topic of the ghost, during which she notes his superstitious beliefs, as well as his general lack of education or refinement, since he is a fieldhand and not a relatively privileged house servant like herself, Lizzy, Charlotte, or others.
