After her father refused a marriage she wanted because she wanted to marry a slave's son, she left Iceland with her father to accompany Erik the Red (or Eiríkr rauði in Old Norse), whose son Þorsteinn she wed. They undertook an unsuccessful voyage to Vinland. In the end, her husband died after they had arrived in Greenland. After this, she stayed in Greenland and moved to Brattahlíð, where she then married a merchant named Þorfinnr Karlsefni Þórðarson. She and her new husband had a son named Snorri Þorfinnsson, he was the first child ever born in North America of European descent. Shortly after Snorri was born the small family traveled back to Greenland. After a while her husband died and his old farm was given to Snorri. After her son got married, Guðríðr went on a pilgrimage to Rome. She visited the Vatican and Rome and spoke to him about religion and what she had seen. While she was away, Snorri built a church near the estate. When she came back from Rome, she became a nun and lived in the church as a hermit.
