Bearing in mind that Evans was a very common name, the paragraphs below give a framework for guesswork
Mr Evans 15.5.1791 tea at Godwin's / 28.1.1794 Evans at Muir's === these two entries or either of them could have been Godwin's schoolfriend Richard Evans (qv)

8.1.1806 Evans at Joseph Johnson's / 6.11.1807 again ===

11.3.1791 Scott MD at Miss Williams'. The only London MD named Scott at this time seems to have been Dr Charles Scot of 67 Queen Anne St East who died March 1794 (newspapers) age 35 son of late Dr John Scot of 30 Titchfield St. (Boyles 1792 Court Guide also lists a Dr Scott at 22 St Alban St)
at Brand Hollis' 14.5.1791 "Scott a believer in spiritual intercourses lends Paine £40 to aid the publication of his pamphlet, suspended for want of money. (Lewis)" I hope one day to find out who this Scott was - Ed Pope
5.3.1791 Nichols at B Hollis has been coded in GD website to John Nichols of the Gentleman's Magazine but the 1796 list (and the 1794 version) had Nichols MP early in 1791 so this would have to have been John Nicholls 1745-1832 (History of Parliament) a signatory to the Friends of the People 11.4.1792. This also puts in doubt the other dates coded to John Nichols except the one recording his death, and there were no other Nichols in the 1796 list.

Isaac Preston admitted Lincolns inn 1769, eldest son by 2nd wife of Isaac Preston deceased (will PCC 1768) of Beeston St Laurence Norfolk; subscr to Jebb's Works 1787, Law List 1793 counsel Norfolk circuit, recorder of Lynn, died 6.5.1796, will PCC 1796. Likely the Hollis entry in 1791 but cannot be the Tooke's entry as he was dead.
Just possibles are William Preston DNB 1750-1807 dramatist lived Dublin, Thomas Preston DNB 1774-1850 for the Tooke's entry & William Preston DNB 1742-1818 freemason
