Willis's 12.5.1797 after theatre
This may have referred to Willis's coffee house, or to Charles Willis (qv) who first appeared in the diary on 16.7.1797, or to Willis Webb (qv), as Godwin had met a Webb earlier the same day (it seems unlikely Godwin would use his first name although he may have referred to him as Willis on 25.6.1788 when Webb was his pupil - or that may have been someone of the surname Willis)
