Raedburh de Carolingians, daughter of Pepin III "The Short" King of Franks and Berthe of Laon.

The ancestry for Raedburh is not at all sure. The following post by Chris Bennet to soc.genealogy.medieval indicates that she was related to Charlemagn in some way:

There is no contemporary source for Egbert's wife. The name "Raedburh" comes from a medieval manuscript quoted by W. G. Searle (Anglo-Saxon Bishops, Kings and Nobles, London 1899, 343) as "MS Trin Coll Oxf x". She is described there as "regis Francorum sororia" which can only be a reference to Charlemagne; however there is no such sister known. Since Egbert was certainly in exile at Charlemagne's court, it is perfectly plausible that he married his wife there. If the tradition has any value, then the best guess is that she was probably a sister-in-law, but she could just as well have been a lady of the Court. Settipani (La prehistoire des Capetiens, 308 n791) is willing to accept the name.
1. Aethelwulf King of Kent & Wessex
Born 806 at Wessex, England, died Jan 13, 857/58 at Stamridge, approximately 51 years, buried at Reburied at Winchester, Hampshire, England
Aethelwulf, also spelled ETHELWULF (d. 858), Anglo-Saxon king in England, the father of King Alfred the Great. As ruler of the West Saxons from 839 to 856, he allied his kingdom of Wessex with Mercia and thereby withstood invasions by Danish Vikings.
The son of the great West Saxon king Egbert (ruled 802-839), Aethelwulf ascended the throne four years after the Danes had begun large-scale raids on the English coast. In 851 he scored a major victory over a large Danish army at a place called Aclea in Surrey. Aethelwulf then married his daughter to the Mercian king Burgred (853), and in 856 he himself married the daughter of Charles II the Bald, king of the West Franks. Aethelwulf was deposed by a rival faction upon his return from a pilgrimage to Rome in 856, but he continued to rule Kent and several other eastern provinces until his death. In addition to Alfred the Great (ruled 871-899), three of Aethelwulf's other sons became kings of Wessex. [Encyclopaedia Britannica]
