Virtually nothing is now known of his life, but he was apparently deeply venerated as one of the Hexham saints.

By the early 11th century, after the Danes had ravaged this part of the country, it seems that his tomb had been entirely forgotten.

Symeon of Durham writes that Alcmund appeared in a vision to Dregmo, a man of Hexham, urging him to tell Alfred son of Westou, sacrist of Durham, to have his body translated (removed and re-buried as a relic).

[3] In 1154, the church, having been ruined again, was again restored, and the bones of the Hexham saints, including Alcmund, were gathered into a single shrine.

The Scots however pillaged and finally destroyed both church and shrine in a border raid in 1296.
