Dauphin
The Dauphin was the heir apparent to the throne of France under the Valois and Bourbon dynasties.
Guy VIII, Count of Vienne, had a dolphin on his coat of arms and had been nicknamed le Dauphin (French for dolphin). In heraldry, a dolphin device displayed on a shield denotes the oldest son of a family; a crest device displayed denotes the second oldest. The title of Dauphin de Viennois descended in his family until 1349, when Humbert II sold his signeurie, called the Dauphiné, to King Philippe VI on condition that the heir of France assumed the title of le Dauphin. The wife of the Dauphin was known as la Dauphine.
The first French prince called le Dauphin was Charles V.

In literature
In Mark Twain's Adventures of Huckleberry Finn, Huck encounters two odd characters who turn out to be professional con men. One of them claims that he should be treated with deference, since he is really an impoverished English duke, and the other, not to be outdone, reveals that he is "really" the Dauphin, presumably Louis XVII.
