Ælfthryth of Wessex (877 – 7 June 929), also known as Elftrudis (Elftrude, Elfrida), was an English princess and a countess consort of Flanders.
They had the following issue:
- Arnulf I of Flanders (c. 890–964); married Adela of Vermandois
- Adalulf, Count of Boulogne (c. 890–933)
Ælfthryth was an ancestor of Matilda of Flanders, who married William the Conqueror, first monarch from the House of Normandy, which means that following the Norman conquest of England and the death of William I all the monarchs of England were also descendants of the House of Wessex.
Ælfthryth was the subject of the award-winning young adult novel Journey For a Princess by Margaret Leighton (1960: Farrar, Straus and Cudahy, New York, NY). In this book, she is called Elstrid.
