Uncle Bo is Anna’s uncle who lives in the West Indies. He’s a heavy drinker who often finds himself at odds with his Anna’s stepmother, Hester, who disapproves of the life he leads. Hester reveals in a conversation with Anna that Uncle Bo has impregnated many Black women in the West Indies. He apparently makes no secret of this, even giving these children his last name—something Hester finds inexcusable, as she’s quite racist and thinks Uncle Bo is dishonoring the family name. When Hester asks Uncle Bo to pay for half of Anna’s passage back to the West Indies, Uncle Bo writes a letter refusing to give her any money. He points out that Hester should use the funds she received from selling her late husband’s estate, taking issue with the implication that Anna is his financial responsibility. Although Anna reads this somewhat hurtful letter, she still has fond memories of Uncle Bo, who at least says he’d be happy to have her live with him, as long as Hester pays for her to do so.
