Commentary
Cawley: "Flodoard refers to "Ludowicus Alpheidi filie sue uxori Begonis comitis". The Annales Hildesheimenses name "filiam imperatoris…Elpheid" as the wife of "Bicgo de amici regis" when recording the death of her husband. Settipani discusses the debate about the paternity of Alpais, preferring the theory that Emperor Charles I was her father. If Emperor Louis was her father, it is unlikely that she was born before [793/94], given his known birth date in 778. It would therefore be chronologically tight for her to have had [three] children by her husband before his death in 816. However, no indication has been found in primary sources of the ages of these children when their father died. The question of her paternity is obviously not beyond doubt, but it is felt preferable to show her as the probable daughter of Emperor Louis in view of the clear statement in Flodoard. If Alpais was the daughter of Emperor Louis, it is likely that she was not her husband's only wife in view of his estimated birth date. After her husband died, she became abbess of Saint-Pierre-les-Dames at Reims in [817]. She was still there 29 May 852."
