St. Benno was appointed in 927 to the See of Metz (north-eastern France) by Henry I the Fowler, King of East Francia (r. 919–936), however a combination of local politics and the zeal with which he worked to end ecclesiastical abuses led the populous to revolt.

In many cases there are several spelling versions of the names of saints from the British Isles. I use the Oxford Dictionary of National Biography version as the primary version with the more prevalent version in parenthesis e.g. Ceadda (Chad) of Lichfield.
