records that Karlsefni left Greenland with 60 men and five women, following the route taken by Leif and Thorvald Eiriksson.

[8][c] In Vinland, Gudrid bore Thorfinn a boy, Snorri,[9][10] who was the first child of European descent known to have been born in the New World.

The exact location of Thorfinn's colony is unknown, though it may have been the Norse settlement at L'Anse aux Meadows, Newfoundland.

Excavations of Thorfinn's home in Greenland in 1930 revealed a deposit of anthracite coal identified as having originated in the vicinity of Rhode Island.

shifts over to Karlsefni the credit for naming numerous geographic features, from Helluland and Markland to Kjalarnes "Keel Ness", though "this flatly contradicts the Grœnlendinga saga and is assuredly wrong".

[16] Helluland (Baffin Island) and Markland were named by Leif; Kjalarness was where Thorvald had wrecked his ship, and the keel was left to stand as a monument,[17] and not an anonymous shipwreck as Eir.

Eirik the Red's Saga depicts Thorfinn Karlsefni as a successful merchant from Reynines, Skagafjord, in the north of Iceland.

Thorhall's group declared the whale to be a boon from Thor, offending the Christian members and they part ways.

The natives return after three weeks with hostile intent, a skirmish ensues, and the Greenlanders attempt as best they can to flee into the forest.

Karlsefni and his men are saved by Freydis, who scares the natives off by slapping her bare breast with a sword taken from one of the fallen Greenlanders.

[22] This estate was located in the Skagafjord bay area,[22] which is also where Thorfinn's great-grandfather established roots, at his farm of Hofdi [is] in Hofdastrand [is].

[13] However, Haukr's ancestral trace before Karlsefni's great-grandfather Thord of Hofdi deviates from other sources, and the Landnámabók version[20] is deemed more reliably accurate.

[24] In the early twentieth century, Icelandic sculptor Einar Jónsson was commissioned by Joseph Bunford Samuel to create a statue of Thorfinn Karlsefni through a bequest that his wife, Ellen Phillips Samuel, made to the Fairmount Park Art Association (of Philadelphia, now the Association for Public Art).

[28][29] In the early morning hours of October 2, 2018, police were called to the statue's location and found it had been toppled from its stone base and dragged into the nearby Schuylkill River.

[32] The 1967 comedic science fiction novel The Technicolor Time Machine by Harry Harrison reveals at its ending that the character named Ottar—an 11th-century Viking hired by a film studio as consultant and actor—is indeed Thorfinn Karlsefni.

As an old woman, Gudrid recounts her childhood in Iceland, her family's harrowing voyage to Greenland, her marriages, and the trip to Vinland led by Thorfinn Karlsefni.

A fictionalized version of Thorfinn Karlsefni is the protagonist of the 2005 manga series Vinland Saga, which was adapted into an anime in 2019.
