 Ælfweard's "sudden and convenient" death followed 16 days after that of his father, but Æthelstan appears not to have been recognised as king by the West Saxons until a year after his father's death, suggesting that there was considerable resistance to him and perhaps also support for Edwin.The contemporary evidence for Edwin's life is very limited.At some point during the reign of his half-brother Æthelstan, Edwin witnessed a charter, S 1417, at New Minster, Winchester, granting lands to one Alfred, a thegn ("minister") of King Æthelstan.
