Hræthhun
Hræthhun (or Rethhun or Hrethhun) Bishop of Leicester, died in 839 or 840.
Hræthhun was consecrated bishop between 814 and 816. He was styled Abbot of Abingdon in a charter dated 811. However, this charter was found to be a forgery, and so Kelly (2000) excluded him from the list of abbots.
