Mensdorff-Pouilly
Mensdorff-Pouilly is the name of a noble family originally from Lorraine. The family derives its name from the barony of Pouilly at Stenay in Meuse.
In 1790, during the French Revolution, Albert Louis de Pouilly (1731-1795) emigrated with his family. His sons Albert and Emmanuel changed the family name to Mensdorff-Pouilly, named for a place in the county of Roussy in Luxembourg.
In 1818, the Austrian branch of the family received a comital title from the Austrian Emperor and was recognized as noble in Bohemia in 1839 (the Inkolat). The family motto is Fortitudine et caritate.
