Duke of Poix
Duc de Poix in the French peerage was created by Louis XIV in 1663, for Charles de Créquy, who served as ambassador to Spain, England, Rome and Bavaria.
The title was taken from de Créquy's home town of Poix-de-Picardie but it became extinct when he died in 1687 without a male heir. It now forms one of the secondary titles of the current ducs de Mouchy.
