Ketil Kalf and Gunhild of Ringanes had a son called Guthorm, and he was
a sister's son to King Olaf and Harald Sigurdson. Guthorm was a gallant
man, early advanced to manhood. He was often with King Harald, who loved
him much, and asked his advice; for he was of good understanding, and
very popular. Guthorm had also been engaged early in forays, and had
marauded much in the Western countries with a large force. Ireland was
for him a land of peace; and he had his winter quarters often in Dublin,
and was in great friendship with King Margad.
