James Humphreys DNB 1768-1830 said in DNB to have been a friend of Horne Tooke, was perhaps all 5 entries at Tooke's, despite a change of spelling, and may have also been the two at Northcote's and one at the RA exhibition. The artist Ozias Humphrey DNB 1742-1810 should be mentioned but in my view was not likely. There was an honorary exhibitor at the RA in 1800 called C Humphreys who showed a 'View of Marks in Essex' but I have found no more about him, unless he was the Charles Nathan Augustus Humphris or Humphries, auctioneer of St Pancras, Middlesex, will PCC 1814, born 1779 St Anne Soho son of William & Annie Humphris. James Humphreys didn't marry till 1822 so the Humphreys's at Tooke's in 1801 may have included his older brother Samuel, who was admitted to Lincolns Inn 1789 the same year as James, but went out to India where he married in 1799 Ann Popham, daughter of Joseph Popham of Cork, British consul at Tangiers. Their son Erskine Humphreys was baptised at Ludlow, Shropshire in 1804 and when he was admitted to Lincolns Inn in 1820 his father's address was given as Wimbledon, which is where Tooke lived till his death in 1812. It was probably he who spoke at an election meeting for East Surrey (Morn Chron 8.11.1832). His death on 29.6.1840 was reported in the Standard of 2.7.1840, at Wimbledon, in his 81st year. I wondered if he might have been the Samuel Humphreys who was Queen Caroline's agent at Milan and Naples during her divorce trial 1820 (see Nat Arch TS 11/105). Another brother of James and Samuel Humphreys was Richard who died in India or Ceylon in 1806. His will PCC 27.4.1807 left a certain sum of money to pay off his brother Samuel's debts or else to go to his brother James absolutely, which suggests Samuel had got into financial difficulties. The 1834 entries spelt Humphries, as had been those at Tooke's and at Northcote's since 1802, might have been Samuel or maybe belong to some other Humphries.

Despite three other spellings for possibly the same person (see above) these were the only ones spelt Humphrys and all occurred within a month, so I think we can assume this was a distinct person. George Humphrys was an officer of Bow Street (Old Bailey online 18.7.1810). He may have been the same as George Humphrys will PCC 28.7.1834 gent of Milman-street, whose address when one of his children by his wife Jane (née Jeremiah) was baptised in 1794 at Holborn was given as "at Honble Thos Erskine's Serjeants Inn", so he was perhaps a married servant to Thomas Erskine (DNB 1750-1823). There were also several attorneys of the name variously spelt, and one (Ambrose Humphrys of 14 Harpur-st Bloomsbury) who used this spelling. There was a Charles Humphreys officer of Bow Street (Old Bailey online 19.9.1810). Other London attornies of the name practicising in 1807 were the brothers Charles (wiil PCC 30.11.1830) and Asher (will PCC 6.11.1819) Humphreys and a John Humphries (will PCC 20.7.1831)
