Lefevres 15.10.1804 adv at Holcroft's / 28,10.1804 Lefevre adv at Hts / 30.11.1804 again
Charles Shaw Lefevre Hist of Parl 1759-1823 was MP for Reading from 1802 to 1820 and by 1808 he had moved from being a supporter of Pitt via Addington and Sidmouth to voting for Burdett's reform motion in a minority of 15. Sidmouth considered he had been "bitten by a popularity" at Reading where the reform movement was strong but I note he voted for Graham in Westminster in 1802, so it's not impossible he was friendly with Holcroft in 1804, but it seems an improbable identification
