It was the Mortemarts, starting with the Governor of Paris in 1700, who lived in the hotel at number 14 rue Saint-Guillaume until the 19th century. This illustrious family can be traced back through the Rochechouarts of Limoges to 1272, and its name has closely followed that of the sovereigns for three centuries. The Mortemart coat of arms, as complicated as a distant genealogy, comprises eight quarters: de Maure, de Bourbon, de Rohan, de La Rochefoucauld, de Milan, de Navarre, d'Escars and de Bretagne. The successors of this noble family in the old quiet hotel were the Guébriants; then the Dauchezes, among others.
The front door features two heads in profile, wearing plumes. The bas-reliefs feature various attributes behind the helmets: a torch and beam for one, a quiver and hunting knife for the other.
