@plainoldme,
In 985, Erik Thorvaldsson (Erik Raudi, or Erik the Red) lead settlers from Iceland to Greenland to found his colony. One of them, Herjolf Bardsson, was a "retired" merchant--meaning he traded in Iceland, but no longer went to sea. His son Bjarni Herjolfsson went to sea, and brought the goods back to Iceland to be traded. Typically, he would "overwinter" one year in Norway, and then bring the goods back to Iceland, overwintering there before returning to Norway.
In the summer of 985, when he returned to Iceland, he found a message from his father that he (Herjolf) had gone out to Greenland, and giving him the latitude and the sailing instructions. Bjarni started out with most of the trade goods he had brought from Norway, and those members of his crew who were willing to stay with him. He was blown off course, though, and when he finally sailed free of bad weather, he found himself on a strange coast. We now know that he was on the coast of what we call Newfoundland. He sailed up the coast, and the coast of Labrador, and when he had reached the proper latitude, he turned east and sailed for Greenland, making landfall at Herjolfness, where his father had set up at the southern end of the new settlements.
About a dozen years later, Leif Erikkson bought Bjarni's ship from him, and got information from him about the lands he had seen in the summer of 985. So, about 997 (the date is disputed), Leif sailed almost directly to the coast of Newfoundland, and found what came to be known as Vinland the Good. Leaving aside all of the controversies about exactly where it was, and focusing only on the story i am presenting you, this lead to an expedition in about 1002. There had been a falling out between Leif and his father Erik, and Leif wouldn't give anyone information on where his Vinland was located. So, his brother Thorvald Eriksson, his bastard half-sister Fredis Eriksdottir with two Icelandic traders, and an Icelandic trader named Thorfinn Karlsefni sailed to the Labrador coast and then sailed south looking for Leif's Vinland.
The winter before, Thorfinn had brought a cargo to Greenland, and there he had met Gudrid Thorbjornirsdottir, a daughter of an old friend of Erik, who had come out to Greenland, and met and married Erik's son Thorstein. Gudrid and Thorstein had gone up the west coast of Greenland two years earlier to some land Thorstein had claimed there, but Thorstein died of disease over the winter, and Gudrid was now a widow, but the owner of valuable lands in Greenland. Thorfinn married her, and she accompanied him on the expedition to find Vinland. Their son was born in Newfoundland, and the settlement site (obviously not Leif's Vinland) has been found on the Great Northern Peninsula of Newfoundland, at Anse aux Meadows.
Once again, leaving aside the historical controversies, i thought you might enjoy reading a relatively reliable historical novel about Gudrid. It is entitled
The Sea Road, by Margaret Elphinstone. I have some doubts about the saga sources she used, but by and large, she hews to the historical evidence about Gudrid, and there can be no doubt that Gudrid was real, and that she lived the life Miss Elphinstone has described for her, although Miss Elphinstone has certainly taken literary license, as one can expect from an historical novel.
You should be able to get it through your local library, and i'm sure you would enjoy it.
