Johanna’s uncle, a German immigrant, whom Captain Kidd and Johanna meet after a long journey through Texas. Although he seems traumatized and outraged by the deaths of Johanna’s parents, he’s also cold and unwelcoming towards his orphan niece, showing no empathy for the trauma she’s suffered or the challenge she faces in adapting to Anglo-American society. Like his wife, Anna, Wilhelm treats Johanna like a farmhand, not a child, until Captain Kidd returns and takes her away.
