Geirmund Hjørson, called Heljarskinn, was a leading Icelander of the late ninth century. He was the son of a Norwegian king and a Samoyed woman. His nickname, an apparent reference to his complexion, means "Hel skin", which indicates either dark or "black" skin or perhaps skin "pale as death".
The sources for Geirmund's life are the Landnámabók and the Geirmundar þáttr heljarskinns, the first saga in the Sturlunga saga collection. According to these, he inherited his father's kingdom in Rogaland but upon returning from a raid on Britain Harald fairhair had seized his land and saw he no other option than to depart. In Iceland, he held four large estates and travelled with a bodyguard of eighty men. His lifestyle was supported by the wealth from his raids and could not be sustained off of his estates alone.
