Ketill flatnefur lived at Raumsdalur in Norway. He had a daughter called Unnur djupudga. She is the ancestress of the main characters in Laxdaela saga. Her great-grandson, Hoeskuldur Dala-Kollsson is the father of Olafur pa. Olafur pa was one of the greatest men to be born in Iceland. He was very handsome and clever. Olafur married Thorgerdur, daughter of Egill Skalla-Grimsson and they had the son Kjartan. Kjartan was even more handsome than his father. They lived at Hjardarholt. Olafur and Thorgerdur fostered Bolli, but Bolli's father, Thorleikur Hoeskuldsson, was Olafur's half-brother.
Gudrun Osvifursdottir is one of the main characters in the story. She, Kjartan Olafsson and Bolli Thorleiksson play the main roles in the second half of Laxdaela saga. The climax of the story is when those three become enemies.
Most persons in Laxdaela saga are rich and handsome people. Some of the minor characters are evil and even ugly!
