Thorfinn must have been given his nickname, Karlsefni, at an early age, since it means “promising boy.” His grandfather in about 900 had led many Norwegians to colonize Iceland, and by 986 their descendants felt so hard-pressed for stock-farming land there that they followed the lead of Erik the Red and migrated to Greenland. Thorfinn, who was a successful trader and sea captain, reached what was known as the eastern settlement of Greenland with a group of colonists in 1003. There he married Gudrid, who was the widow of one of Erik the Red’s sons, Thorstein.
