Bertrada of Prüm

Bertrada (b. ca. 670 - d. after 721), also called Berthe or Bertree, and perhaps a Merovingian princess, is known to be the mother of Caribert 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 Younger, Bertrada is the great-grandmother of Charlemagne.

There is some dispute as to her husband and parents. The following are two of many possible scenarios:

* She was daughter of the seneschal and Pfalzgraf Hugobert and Irmina of Oeren. Her husband is unknown.
* She was daughter of Theuderic III, king of Neustria and Austrasia, and Clotilda of Heristal. She married Martin of Laon. (This is shown in "The Royal Ancestry Bible Royal Ancestors of 300 Colonial American Families" by Michel L. Call; Chart 2001)
