Siegfried II, Count of Stade

Siegfried II (956-1037), Count of Stade, youngest son of Henry I the Bald, Count of Stade, and his wife Judith von der Wetterau, granddaughter of Gebhard, Duke of Lorraine.

The writings of Thietmar of Merseburg described the deaths of his three maternal uncles Henry, Udo and Siegfried, captured by pirates with Count Adalgar, and reported that Udo was killed in battle with the pirates. Siegfried eventually escaped from captivity to seek help for the remaining captives.

Siegfried married Adela of Rhienfelden, daughter of Gero, Count of Alsleben, and his wife Adela. Siegfried and Adelaide had three children:

• Lothair Udo II, Count of Stade, and Margrave of Nordmark (as Lothair Udo I)
• Irmgard von Stade, Abbess of Alsleben
• Bertha von Stade, Abbess of Alsleben.

Siegfried was succeeded as Count of Stade by his son Lothair.
