Editorial note — APPENDIX.
Reading edition
Alfric probably refers to Æthelric who, once bishop of Durham, retired to Peterborough—he was imprisoned at Westminster by William. Siward Beorn, called also Barn (Siwardus cognomento Barn, Lib. Elien.) a Northumbrian Thegn and a son of Æthelgar, was undoubtedly with Hereward at the Camp of Refuge.
