Snorre names "the king's daughter Ingegerd" when recording that she was used as intermediary to effect a reconciliation between her father and Olav Haraldson King of Norway, and that her marriage to the Norwegian king was proposed. Adam of Bremen names "filius Iacobus et filia Ingrad" as the children of "Olaph rex Sueonum" and his wife Estred, specifying that Ingrad married "rex sanctus Gerzlef de Ruzzia". Morkinskinna names “Queen Ingigerdr the daughter of King Óláfr the Swede” as wife of “King Yaroslav [of] Russia”. Her birth date range is estimated based from the birth of her oldest child in 1020, and her youngest known child in . Snorre records the betrothal of "Ingegerd the king's daughter" and "King Jarisleif…from Russia". The Historia Norwegie records the marriage of "sororem Olaui Sueonensis…Margaretam" and "rex Iarezlafus de Ruscia" at her brother's instigation, after her betrothal to Olav of Norway was terminated. It is more probable that she was the daughter rather than sister of King Olof if it is correct that she had ten children by her husband. She is referred to as IRINA in Russian sources.
