 Geoffrey Gaimar in "Lestoire des Engles" states that she was daughter of the Hungarian king and queen ("Li reis sa fille"), although he places the marriage at a time when Edward is thought still to have been in Kiev, while Orderic Vitalis in "Historiae Ecclesiasticae" is more specific, naming her father as king Solomon ("filiam Salomonis Regis Hunorum"), even though he was actually a contemporary of Agatha's children.William of Malmesbury in "De Gestis Regis Anglorum" states that Agatha's sister was a Queen of Hungary ("reginae sororem") and is echoed in this by Alberic of Trois-Fontaines, while, less precisely, Ailred says of Margaret that she was derived from English and Hungarian royal blood ("de semine regio Anglorum et Hungariorum extitit oriunda").Finally, Roger of Howden and the anonymous "Leges Edwardi Confessoris" indicate that while Edward was a guest of Kievan "king Malesclodus" he married a woman of noble birth ("nobili progenio"), "Leges" adding that the mother of St Margaret was of Rus royal blood ("ex genere et sanguine regum Rugorum").
