Duke of Chevreuse

Duke of Chevreuse (French Duc de Chevreuse) was a French title of nobility, elevated from the barony of Chevreuse in 1545. Originally created for Jean de Brosse, Duc d'Étampes, it was transferred in 1555 to Charles of Guise, the Cardinal of Lorraine, and became a possession of the House of Guise, becoming the title of the Cardinal's grandnephew, Claude de Guise (1578–1655). It was sold in 1655 to his wife, Marie de Rohan, who transferred it to the son of her first marriage, the Duc de Luynes. It has since been held by the ducs de Luynes.
