Barney is the disabled son of Edward and Mae McSwiney and is Teddy’s younger brother. Barney is physically deformed, and he also suffers from a learning disability. He is a gentle, vulnerable boy who’s often ostracized and picked on by the Dungatar community because of his disabilities. The Dungatar residents once tried to have Barney committed to an insane asylum, even though he had done nothing wrong and is not a danger to himself or others. Barney is always accompanied by a member of his family, because Mae worries that the Dungatar townspeople might try this again. Barney befriends Tilly, who is kind to him and empathizes with him because she is also gossiped about and treated like an outcast. After Teddy dies, however, Barney is heartbroken and he leaves Dungatar with his family shortly after.
