Bertrada of Prüm

Rear of the towers of the Bertradaburg in Mürlenbach, Germany

Bertrada castle in Mürlenbach, named after Bertrada of Prüm

Bertrada (b. ca. 670; d. after 721), also called Berthe or Bertree, is known to be the mother of Charibert of Laon, with whom she is co-founder and benefactor of the Prüm Abbey. They founded the abbey in 721.

Through Charibert's daughter Bertrada of Laon, wife of Pippin the Short, Bertrada is the great-grandmother of Charlemagne. The identity of her husband is unknown.

Bertrada and her husband had three children:

• Hardrad (d. after 720)
• Charibert of Laon
• Weta, married Cario.

Three alternative solutions to the question of her parentage have been suggested:

• She was daughter of the seneschal and Pfalzgraf Hugobert and Irmina of Oeren
• She was the daughter-in-law of Irmina (d. ca 704), daughter of Hugobert and Irmina, and her husband Charveus, Count of Laon, brother of Lambert, Count of Hesbaye
• She was daughter of Theuderic III, king of Neustria and Austrasia, and Clotilda of Herstal.

The last two possibilities are not mutually exclusive.
