|Pseudonym and/or alternative name used by/for Gregory, Edward|
|Link for biographical information not available|
|Additional comments: No further information can be found. In various books referred to as Rev. mr. Gregory, Rev. Mr. T. Gregory, Rev. Mr. T. Gregory or just Gregory, all for the same chant.
Probably a copyist error and referring to Rev. Edward Gregory of whom Bemrose gives biographical details (although a different chant in Bemrose).
