Thomas Evans and his wife Janet are well covered by Ian McCalman in his excellent book Radical Underworld. Evans first appeared in LCS records in 1795, first as a delegate from Div 40 and elected to the Exec Cttee 10.9.1795. Alexander Galloway was described as his brother in law (probably by Francis Place but I haven't searched for the exact source yet). Galloway had a sister Janet born 24.10.1777 but I could find no record of her marriage.
From meeting of Div 23 on 11.12.1793 in Brown Bear, Moorfields the spy George Lynam reported that Davis went to a Serjt at the Tower and made a convert of him & several Soldiers. On 20.12.1793 Home Secretary Evan Nepean wrote to Major General Leake that a shoemaker named Davis of 15 Cannon Street had been spreading sedition to soldiers at the Tower. (Thale p.34). He may have been the same as Peter Davey or Davie who testified at the LCS trial of Lynam 13.6.1793 that he had enquired about Lynam's character from a Mr Crab and then proposed him as a member.
Nat Arch TS 11/963 examination of Thomas Hardy, who mentioned Bayley a printer with 5 or 6 journeymen. Hardy answered questions freely but perhaps not honestly, to protect comrades. This could have been Thomas Bayley printer of Petticoat Lane, but no evidence he was sympathetic to LCS, and he was dead 3 years before Hardy's exam.
