Æthelmund is believed to have married Ceolburh (d. 807), who is recorded by John of Worcester as an abbess of Berkeley, Gloucestershire.
Æthelmund is attested in several Mercian and Hwiccian charters in the late 8th century, all thought to reference the same person.
He seems to have been succeeded as Ealdorman of the Hwicce by his son Æthelric, who issued a charter in 804 [4], in which he gave land to his mother, Ceolburh, presumably Æthelmund's widow.
[1] According to the ASC, Æthelmund rode south the same day Egbert succeeded to the throne,[6] crossing the river at Cymeresford but was met by Weohstan, Ealdorman of the Wiltshire, with a host numbering in the hundreds.
In 1670 a number of spearheads and iron bits were dug up in a field known as "the Battlefield" near Kempsford, which has led to speculation[7] that this was the site of battle.
