The son of Mattie and Troy Chatham, young Jimmy has the same kind of soul and principles as his grandfather Athey Keith. He learns from Athey and works on Athey's little farm, using the animals and natural conservationist methods that Athey employed. Jimmy did not enjoy working for his father, sitting on a huge tractor and involving himself in agribusiness. When Athey passes away, Jimmy starts to go a little wild, but eventually joins the military and is killed in Vietnam. In his grief, Jayber recalls the feel and shape of Jimmy Chatham's head when he cut his hair as a child.
