    Birth Abt 0925 
    Gender Female 
    Death Aft 29 Sep 0976 
    Notes 
    • Bieletrud or Biletrud was the wife of Berthold, Herzog von Bayern (Duke of Bavaria) of the Luitpoldinger family, and the mother of:

      Heinrich III, succeeded as Herzog von Karnten (Duke of Carinthia) and later Herzog von Bayern;[1]
      possibly Kunigunde, married Ulrich, Graf von Schweingau.[2]
      No dates for the marriage or her birth are known, but given Berthold was unmarried in 939, (see below) the marriage was perhaps in about 940, and her birth in about 925.[3]

      Berthold died 23 November 947, and Bavaria was granted to Otto I's brother Heinrich and not Berthold and Biletrud's son, who was probably a minor.[4]

      It is possible Biletrud was involved in the rebellion of Otto I's son Liudolf in 953[3] which might explain why the Emperor Otto II, through the intercession of his wife Theophana, granted Biletrud the return of lands on 29 September 976.[5]

      Parents
      Berthold for his support of Otto I, Emperor of Germany was offered to be connected to Otto by marriage, either by marrying Gerberga, Otto's sister, the widow of Giselbert of Lotharingia, who had rebelled and died in 939, or an unnamed daughter of Giselbert and Gerberga, who was almost of marriageable age. Berthold decided he would wait for the daughter to come of age.[6]

      For this reason some researchers believe Biletrud is the daughter of Giselbert of Lotharingia and Gerberga of Saxony[4]however the consensus seems to be that this is unlikely, and either the proposed marriage with the daughter was abandoned or she died before the marriage could take place.[3]

      Biletrud's parents are then unknown.[2];[1] However this does mean that in 939 Berthold was unmarried and the marriage with Biletrud probably took place about 940.
