Æthelred of Wessex of Asser's "Life of King Alfred the Great" refer to a "mysterious 'Wulfthryth regina'", but Keynes stated in 1994 that she was "presumably the wife of King Æthelred".

He succeeded his
Æthelwold ætheling sons in succession. King Æthelbald died in 860, and King Æthelberht in 865; Æthelwold's father, Æthelred, then succeeded to the throne. In the same year the Viking Great Heathen Army invaded England. Within five years they had conquered Northumbria and East Anglia, and forced Mercia to buy them off.

Æthelred died shortly after Easter that year, leaving young sons. Primogeniture was not established in this period, and it was
