What happens when Beowulf first arrives on the shore of horthgars lands

When Beowulf first arrives on the shore he has to explain who he is and why has he come. He is instantly greeted by people who show that they know about him based on his family. This was a very important moment because according to the anglo-saxon old laws everything that his ancestors have done before him, counts as if he had done it. If they did something shameful then he should also be ashamed, and if they were honorable then he would be honorable too.
