- William Gregory of Guildford was a member of the House of Commons and held the office of mainpernor in June 1406 . His name is mentioned again in a pardon (murder of Gregory's servant). The last mention was made when he was elected Knight of the Shire in 1414. Since his year of birth and death cannot be narrowed down, his "life dates" are given as fl. 1406-1414.
