Ceorl served as a messenger of Rohan during the War of the Ring. He rode from the Fords of Isen with the news that Erkenbrand has been defeated. He assumes that Théoden remains in Edoras while Eomer rides to war, but is shown that he is mistaken. He joined Theoden's army and presumably fights at Helm's Deep. His fate in that battle, and / or afterwards, is unknown.
