      “BAUDOUIN II the Bald, Count/Marquis of Flanders, 879-918, Count of Artois and Lay-abbot of Saint-Vaast, 892-899, Lay-abbot of Saint-Bertin, 900, Count of Boulogne, 898? -918, Count of Ternois, about 892-918, 2nd and eldest surviving son and heir, born about 863-865. He married in 884 ÆLFTHRYTH (or ELSTRUDE) OF WESSEX, daughter of Alfred the Great, King of Wessex, by Ealswith, daughter of Æthelred Mucil, earldorman of the Gaini. She was born about 870. They had two sons, Arnulf (I) [Count/Marquis of Flanders] and Adalolf (or Adolf), and two daughters, Ealhswid and Ermentrude. In 918 his wife, Ælfthryth (or Elstrude), "daughter of the King of the English," gave Liefasham [Levisham], Kent to the Abbey of Mont-Blandin in Gand. BAUDOUIN II, Count/Marquis of Flanders, died in 918, probably 10 Sept. His widow, Ælfthryth (or Elstrude), died 7 June 929. He and his wife were buried in the abbey of Saint-Pierre, Gand.
