The date of this marriage is estimated from the estimated birth date of the couple's eldest son. The primary source which confirms the marriage has not yet been identified. The Gesta Hungarorum reports claims that the three brothers Levente, András and Béla were "ex duce Wazul progenitos ex quadam virgine de genere Tatun [Tátony]" rather than legitimate. 1
