hi - just noticed one error you have while Googling something else:
Cantata 191 came AFTER the B minor mass. Bach pulled parts of the Gloria from 1733 to re-use for Christmas sometime in the years 1743-1746. You can read more in any of John Butts articles or Cambridge Companion or other sources.
Good luck with your article. It is certainly a worthy subject.
