Until what year was the king who Æthelgeard was an official for King of England?
Æthelgeard Æthelgeard, also Æthelheard (fl. 950s) was a 10th-century landowner who was known to have been involved in service to the royal family, likely an official of Eadwig.
Æthelswith Æthelswith (c. 838–888) was the only known daughter of King Æthelwulf of Wessex. She became Queen Æthelswith when she married King Burgred of Mercia in 853. The couple had no issue. Her marriage probably signalled the subordination of Burgred to his father-in-law and the Saxon kingdom at a time when both Wessex and Mercia were suffering Danish (Viking) raids. Burgred also had ongoing problems with the Kingdom of Powys on his western border and in 853 Æthelwulf subjugated the Welsh state on Burgred's behalf.
