Family name origins & meanings

  • Polish : from an Old Slavic personal name, Trojan, a derivative of Latin Traianus. This was the name of a Roman emperor (53–117), who extended the Roman Empire east into Dacia (modern Romania). In early Slavic records the name is also borne by a mythical creature.
  • Czech and Slovak : from the Old Czech vocabulary word trojan ‘triplet’, from the numeral tři ‘three’. This was used as a personal name, bestowed on children born on the Feast of the Holy Trinity, and as a surname for people living at a house distinguished by the sign of a Golden Three.
  • The surname is also well established in Germany, of Slavic origin.
  • French : from the Latin personal name Troianus (see Italian Troiano). This gained currency in France as having been the name of a 6th-century bishop of Saintes.
