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