|Name Comte Troisville|
|Died 1672, Trois-Villes, France|
Jean-Armand du Peyrer, Comte de Troisville (or Tresville) (1598 at Oloron-Sainte-Marie – 8 May 1672 at Trois-Villes) was a French officer. He was fictionalized under the name Monsieur de Tréville in Alexandre Dumas's novel The Three Musketeers.
Du Peyrer was not from aristocratic stock, but of recent nobility. It was his father, Jean du Peyrer, who introduced the name de Trois-villes or Tréville into the family. In 1607 he bought the region of Trois-Villes which effectively brought him nobility, according to the customs of the Basque Country at the time. This purchase also allowed the elder Du Peyrer the right to be considered a gentleman and to sit upon the council of gentlemen in the viscountcy of Soule.
