Esico of Ballenstedt

Esico of Ballenstedt (died around 1060) is the progenitor of the House of Ascania, i.e., the oldest known member of the house. Little is known about him, but he is assumed to have been count of the Schwabengau and of the Harzgau with his seat at Ballenstedt. His father is sometimes assumed to have been Count Adalbert I, but there is no hard evidence for this. Esico is assumed to have inherited properties from Odo I, Margrave of the Saxon Ostmark, who may have been his maternal grandfather.

He was succeeded by his son Adalbert II, Count of Ballenstedt.
