What Does the Name Thorfinn Mean?
Thorfinn is an English form of the Old Norse masculine name Þorfinnr. It is a compound of Þórr, the Norse thunder god, and finnr, an Old Norse word for a Finn or Sami person. The usual literal sense is 'Thor's Finn,' and it is sometimes given as 'Thor the Finn.' The first element is theophoric, invoking Thor; the second is an ethnic or byname term, not the same as the modern given name Finn in every case. The precise reference of finnr in this compound - whether to a Finnic person, a Sami person, or another northern group - is not fully settled.
Thorfinn Name History & Origins
The name is recorded in medieval Scandinavian sources as Old Norse Þorfinnr. It appears in Icelandic and Norwegian historical and saga writing, and it was borne by several notable figures. Thorfinn Karlsefni was an Icelandic explorer who led an attempted Norse settlement in Vinland around the year 1010; his story is told in the Vinland sagas. Thorfinn Sigurdsson, Earl of Orkney in the eleventh century, was known as Thorfinn the Mighty and appears in Orkneyinga saga and related texts. A tenth-century Earl of Orkney, Thorfinn Skullsplitter, is also named in Norse tradition.
The Old Norse nominative Þorfinnr developed into modern Icelandic Þorfinnur and Norwegian Torfinn. In English, the Old Norse letter þ (thorn) is represented by th, producing the spelling Thorfinn. The name came into English use through translations of Old Norse literature and through Scandinavian contact and immigration, and it remains current in Iceland and Norway in its local forms. A modern fictional Thorfinn appears in Makoto Yukimura's manga Vinland Saga, a literary use inspired by the historical Thorfinn Karlsefni and separate from the medieval record of the name.
