What were the names of the monks who watched Becket die?

The monks who witnessed Thomas Becket's murder in 1170 were named Edward Grim, a cleric who was injured while trying to defend Becket, and a few others who were present in Canterbury Cathedral at the time. Grim later wrote an account of the event, providing one of the most detailed descriptions of Becket's martyrdom. Other monks present included Reginald of Canterbury and possibly several unnamed witnesses.
