This is the original source naming Æthelred Mucel as the father of Ealhswith. ("Ælfred rex...uxorem de Mercia, nobilem scilicet genere, filiam Æthelredi, Gainorum comitis, qui cognominabatur Mucill, subarravit et duxit.")
↑ There is no known source which gives a place or date of birth or death for Æthelred Mucel.
↑ Baldwin notes that one possible father of Æthelred Mucil was another Mucel who appears in Mercian charters. A second possibility is the Esne who also appears in charters. Neither relationship is certain.
