Þórunn Ketilsdóttir hyrna (‘horn’) was among the original settlers of Iceland in the late ninth century. Together with her husband Helgi magri (‘the lean’), she settled in Eyjafjörður. Her parents were Ketill Björnsson flatnefur (‘flatnose’) and Yngvildur Ketilsdóttir, and they and at least four of Þórunn’s siblings also settled in Iceland. Ketill flatnefur is described in Norse sources as a chieftain in Romsdal, Norway, and a ruler of the Kingdom of the Isles off the coast of modern-day Scotland. The year and location of Þórunn’s birth is unknown.
