In A Christmas Carol, Scrooge's nephew is named Fred. He is the cheerful, sociable relative who repeatedly invites Ebenezer Scrooge to celebrate Christmas with him despite Scrooge's cold refusals.
Fred is the son of Fan, Scrooge's beloved younger sister. The Ghost of Christmas Past reminds Scrooge that Fan once came to bring him home from boarding school, and later shows that she died after giving birth to her child. This family connection helps explain why Fred matters to Scrooge even though the older man initially rejects him.
Fred represents the warmth and fellowship that Scrooge has abandoned. He does not respond to Scrooge's hostility with equal bitterness: at his Christmas gathering, Fred defends his uncle and continues to hope that Scrooge may change. After the spirits transform Scrooge, he accepts Fred's invitation and joins the family celebration. Adaptations sometimes expand Fred's role or give his wife a name, but the original 1843 novella consistently identifies Scrooge's nephew as Fred. Jacob is Scrooge's deceased business partner, Bob is Cratchit's first name, and Tim is the name of Tiny Tim.
