Det tyder på at Magnus datter Ragnhild Magnusdatter ble gift med Håkon Ivarsson, en av Harald Hardrådes jarler. De fikk blant annet datteren Sunniva Håkonsdatter. Hun fødte sønnen Håkon Sunnivasson, som har fått morens navn, ikke farens, og denne Håkon blir i dansk historie henvist til som enten «Håkon Jyde» eller «Håkon Nordmann». Håkon ble gift med Ragnhild Eriksdatter, datter av kong Erik Eiegod av Danmark. Ragnhild og Håkons sønn Erik Lam ble også konge av Danmark (Kilde: fotnote om Håkon den Gode i Wikipedia)
