Clermont

The Clermont were the historic dauphins of Auvergne, a comital line that also held the county of Clermont. Around 1147 William VIII the Old seized the inheritance of his nephew William VII the Young, and the settlement of 1155 left the dispossessed branch with a reduced territory around Vodable. William VII had married Marquise d'Albon, daughter of the count of Viennois, whose byname Dauphin passed to their son.

From Robert II's testament of 1281 the heads of the house styled themselves counts of Clermont and dauphins of Auvergne, and placed a dolphin on their arms. They resided at the castle of Vodable, where successive Roberts and Bérauds ruled through the fourteenth century.

The blood line ended with Béraud III in 1426; his daughter Jeanne carried the dauphinate to the house of Bourbon, and in 1436 it passed to the Bourbon-Montpensier branch.
