8.3.1795 Young at Foulkes' / 28.9.1795 sup at mrs Johnston's, w. miss G(odwin); Young & Campbel / 18.10.1797 at Carlisle's / 12.12.1804 at Johnson's
I can't see now why I suggested Thomas Young DNB 1773 - 1829 for the above four entries, except that he was a surgeon who would have known Carlisle, and an interesting thinker who might have been at Johnson's. (Oct 1794 to Edinburgh, toured Scotland summer 1795, to Gottingen 1795 dissertation Gottingen July 1796, resided 6 terms at Cambridge 1797-9, "appears to have spent as much time as possible in London")
