“ Born during the lifetime of his grandfather Ælfred, Æthelstan was a favourite of the great West-Saxon king, who gave him as a boy a purple cloak, a jewelled belt, and a sword with a golden scabbard, no doubt to mark him out, in spite of his illegitimacy, as a right ætheling. When the young prince was six years old, Ælfred died, and during the stormy years when Eadward was slowly recovering the overlordship of Mercia and Northumbria from the Danish hosts, Æthelstan was sent to be brought up by his aunt Æthelflæd, the Lady of the Mercians, and her husband the ealdorman Æthelred. ”
