[2] On 20 July 1798, the Borough records show that Knapp headed a committee to confer with John Lemprière regarding the Ordinances of Abingdon School.
Lemprière has been the subject of complaints stating he had been negligent in his duties at the School and at St Nicolas' Church.
[5] After an unsuccessful parliamentary election in November 1806 he was defeated by Sir Thomas Metcalfe, 1st Baronet for the Abingdon seat but the following year in the May 1807 election he gained the seat from Metcalfe, winning by a margin of seven.
There were reports that he was thrown from a gig on his head and died from an affection of the brain and fatal fever but there are suspicions that it may have been as a result of a duel.
[2][6] George was a gambler (in 1807 he declined to pay for the Members' Purse at the Abingdon Races).
