Chaplin featured in the memoirs of Sir Robert Heron as the worthy, if somewhat stolid, scion of an old county family, whose ‘ignorance on all political subjects was wonderful’.
Shortly before the election of 1806 Lord Buckinghamshire wrote of him: ‘Chaplin I have little doubt will be a friend to government’, but of his colleague Heathcote added that he was ‘with the present administration’. The premier, however, writing a day later, described Chaplin’s politics as ‘adverse’; and Chaplin subsequently denied that his hostility to Catholic relief in 1807 amounted to turning coat.
In 1809, as recorder of Stamford on his kinsman Lord Exeter’s interest, Chaplin ushered his son and heir into the House. Their attendance was an unknown quantity.
Chaplin died 28 Aug. 1816. Heron described him as
an honourable, virtuous and benevolent man, but he had no head ... his subserviency to ministers made him popular with those who call themselves the loyal party in this county, and his private character was deservedly respected by all.
On the strength of this his heir might have stepped into his shoes at once as county Member, had he thought fit to do so.
