Rotrude

  Notater:

Few clear records remain of Princess Rotrude's early life. She was educated in the Palace School by Alcuin, who affectionately calls her Columba in his letters to her. When she was six, her father betrothed her to Constantine VI of Byzantium, whose mother Irene was ruling as regent. The Greeks called her Erythro and sent a scholar monk called Elisaeus to educate her in Greek language and manners. However, the alliance fell apart by 786 when she was eleven and Constantine's mother, Irene, broke the engagement in 788.

She had a relationship with Rorgo of Rennes and had one son with him, Louis, Abbot of Saint-Denis (800 - 9 January 867). She never married.
