'Alchfrith' or 'Ealhfrith' was a son of King
Oswiu of Northumbria and Rieinmelth of
Rheged.
In around 655 Eahlfrith was appointed by his father as sub-king of
Deira, the southern part of the Northumbrian kingdom. He replaced his cousin
Æthelwold, who had supported Oswiu's enemy
Penda of Mercia in the campaign leading up to the
Battle of the Winwaed. Eahlfrith was married to Penda's daughter Cyneburh; Cyneburh's brother
Peada was doubly Eahlfrith's brother-in-law as he later married Eahlfrith's sister Ealhflæd.
At the
Synod of Whitby in 664, Eahlfrith was the chief supporter of
Wilfrid.
Bede, in the ''
Historia ecclesiastica gentis Anglorum'' (Book III, chapter 14), states that Ealhfrith attacked his father. No further details are known. Bede's ''Lives of the Abbots'' states that Eahlfrith asked his father for permission to accompany
Benedict Biscop on a pilgrimage to
Rome, but the dating of this request is unclear. With this, Eahlfrith disappears from the record.
While generally presumed to be the son of
Aldfrith, a half-brother of Eahlfrith, the possibility is admitted that
Osric may have been a son of Eahlfrith and Cyneburh.
