                  This last saint is Ebrulphus, or Evroul, abbot of Ouche.  The

                      prominence given to St Ethelbert, coupled with the entry

                      of Ebrulf, suggests a cell to the Abbey of Ouche, situated in

                      the sphere of Ethelbert's influence (i.e. Herefordshire), as

                      the home of this Kalendar: but I can find no such place. 

                      There were very few cells of Ouche in England: the

                      principal one was Ware in  Herts.
