  Research Notes:

The Annalista Saxo names "Otto dux de Northeim, genere Saxo, dux autem Bawarie" as son of "Bennonis de Northeim", naming his mother in a later passage.

Graf von Northeim. He was installed as OTTO Duke of Bavaria in 1061 by Agnes de Poitou, mother and regent of Heinrich IV King of Germany. The Annals of Lambert record that "regina Ungariorum, mater Salomonis regis" presented the sword of "rex Hunnorum Attila" to "duci Baioriorum Ottoni" after her son was restored as king of Hungary. He was a vigorous opponent of King Heinrich, who accused him of an assassination plot, deposed him as Duke of Bavaria, confiscated his lands in the Harz area, and outlawed him in 1070. He allied himself with Magnus Billung Duke in Saxony, but was forced to submit to King Heinrich and placed in custody until 1072, when all his crown fiefs were returned to him apart from the duchy of Bavaria. 1
