Gero, Count of Alsleben

Gero was a Count of Alsleben, conjectured to be the son of Siegfried and therefore grandson of Gero the Great. If so, his mother was Hedwig, daughter of Wichmann the Elder. Gero was the brother of Tetta, who established a monastery at Alsleben in his name. Thietmar of Merseburg, whose Chronicon is the major source of information here, refers to Gero as a Count in Northern Thuringia and Morzani. Gero was married to Adela of an unknown family. Gero and Adela had one daughter, Adela of Alsleben, who married Siegfried II, Count of Stade. No other counts of Alsleben are recorded until the 12th century.
