Ruth is the Old Man’s third wife whom he met at Harvard. She followed him to Kenya, where they married and had two sons, Mark and David. A white American woman, Ruth doesn’t accept Kezia as a legitimate wife, so she refuses to let her sons visit Alego. However, she does accept Roy and Auma as her own—until her sons are born and the Old Man is blacklisted from the government. She suffers a great deal of verbal abuse from the Old Man until they finally divorce, and she never makes peace with the rest of the family. Indeed, Ruth changes Mark and David’s last names when she marries a Tanzanian man and is incensed when David insists that he’s still an Obama. Barack meets Ruth when he visits Kenya. During the visit, she consistently speaks poorly about the Old Man while praising Mark for his achievements. Auma tells Barack later that Ruth is the only of the Old Man’s wives who can prove her children’s paternity without a doubt.
