Sixten is of Scandinavian origin, derived from the Old Norse word 'Sigtýr', which means 'victory'. It's composed of two elements: 'sigr' meaning 'victory' and 'frithr' meaning 'peaceful'. This name was brought to Sweden by the Vikings and has been used in Scandinavia ever since. In Swedish, Sixten is often considered a diminutive form of the name Sigurd or Siegfried. It's pronounced /ˈɧʏstɛn/ in Swedish.
In 2014 alone, there were five babies named Sixten. Altogether, there have been five children given this name since records began.
