Æthelred Mucel was an Anglo-Saxon noble from Mercia who was the father of Ealhswith, the wife of Alfred the Great.
He is described by Asser as an ealdorman of the Gaini, a tribe after whom Gainsborough in Lincolnshire is believed to be named.
The woman's mother was called Eadburh, from the royal stock of the king of the Mercians.
[1] According to the historian Richard Abels, Eadburh was a descendant of King Cenwulf of Mercia.
[2] The scholar, Ford Mommaerts-Browne, however, suggests that she was a grandchild of Ceolwulf, through his daughter, Ælfflæd, and her husband, Wigmund.
