Neither King Ælfweard of Wessex nor King Æthelstan (typically called the first King of England) married. Æthelstan was succeeded by his brother, Edmund (Ēadmund), who first married Ælfgifu of Shaftesbury (died 944). She bore two future kings, Eadwig (r. 955–959) and Edgar (r. 959–975). She had a now unknown connection with the royal nunnery of Shaftesbury, founded by King Alfred, where she was buried and soon revered as a saint. According to a pre-Conquest tradition, her feast day is 18 May.
King Edmund: King of England 939–46. The son of Edward the Elder, he succeeded his half-brother, Athelstan, as king in 939. He succeeded in regaining control of Mercia, which on his accession had fallen to the Norse inhabitants of Northumbria, and of the Five Boroughs. He then moved on to subdue the Norsemen in Cumbria and finally extended his rule as far as southern Scotland. He was killed in 946 at Pucklechurch, Gloucestershire, by an outlawed robber.
Björn Järnsida (Ironside), was a Viking raiding France in the 9th century. According to the old sagas he was the son of Ragnar Lodbroks and participated in Ragnars siege of Paris. The sagas also say that Björn got the name Ironside because he was never injured in battle. (Picture from the TV show Vikings).
