Adalbert von Ballenstedt c. 970, (name uncertain, but possibly Adalbert), was Count of Ballenstedt, Vogt of the Nienburg Abbey, and the provost of Hagenrode.
The details of "Adalbert's" life are unclear.
[1][2] It is known that he was the father of Esico, the first to be called "Ascanian," from his marriage with Hidda, daughter of Odo I, Margrave of the Saxon Ostmark.
[3] Hodo was related to Margrave Christian of Thuringia from the Gau Serimunt, from whom, through the descendants of Esico, possessions in this area and the bailiwick of Nienburg and Frose possibly originated.
The Sachsenspiegel reported that Adalbert's ancestors came with the immigration of Swabian tribes around 568 into the area on the Lower Harz known as the Schwabengau, and have settled there.
