Lothair Udo I, Count of Stade

Lothair Udo I (950 – 23 June 994), Count of Stade, son of Henry I the Bald, Count of Stade, and his wife Judith von der Wetterau, granddaughter of Gebhard, Duke of Lorraine. Lothair is frequently confused with his nephew Lothair Udo II, son of his brother Siegfried II, who was Margrave of Nordmark as Lothair Udo I.

The writings of Thietmar of Merseburg describe the deaths of his three maternal uncles Henry, Udo [Lothair Udo I] and Siegfried, captured by pirates with Count Adalgar, and reported that Udo was killed in battle with the Vikings.^[1]

Lothair married an unknown daughter of Siegbert, Count of Liesgau, and had two children:

• Henry III von Stade, Canon at Hildesheim Cathedral, after 1002
• Udo von Stade (986-1040), Count of Liesgau and Rittegau, married to Bertrada of an unknown family. Their son Dietrich I von Kahleberg was killed in the Battle of Werben on 10 September 1056. Dietrich married Bertrada, daughter of Dirk III, Count of Holland.
