Medieval Icelandic tradition relates that Erik the Red and his wife Þjóðhildr (Thjodhildr) had four children: a daughter, Freydís, and three sons, the Explorer Leif Eiríksson, Þorvaldr (Thorvald) and Þorsteinn (Thorstein). Erik himself remained a follower of Norse paganism, unlike his son Leif and Leif's wife, who became Christians. After being baptized by king Olaf Tryggvason, Leif brought the message of Christianity to Greenland, becoming something of an evangelist. While his wife took heartily to the religion, even commissioning Greenland's first church, Erik greatly disliked the faith and stuck to his Norse Gods – which, the sagas relate, led Thjodhild to withhold intercourse from her husband. Thjothhild was the daughter of Jørundur Ulfsson and Thorbjørg Gilsdottir (from whom Gilsfjørd is named). Jørund's mother Bjørg was granddaughter to Irish king Cerball mac Dúnlainge (Kjarval) through his daughter Rafarta.
