Tristen

It is a given name of Welsh origin. It originates from the Pictish name Drustan a diminutive of Drust, probably from the Celtic “drest,” meaning “riot, tumult.” In modern Welsh appears as the noun “trwst” (plural trystau) and the verb “trystio” (to clatter). It became popularized through the character of Tristan, one of the Knights of the Round Table in Arthurian legend. The modern form is most likely influenced by the Latin root “tristis” (“tant triste” in the medieval French version of the myth), meaning “sad, sorrowful.”
