Harris belonged to a Quaker family, who originally came from Fordingbridge, Hampshire. His grandfather Robert Harris (1709-91) married one Elizabeth Cross ‘of London’ in 1739, was established by 1752 as a retail hatter in Cannon Street and later retired to Wandsworth.
The excitement proved too much for Harris, and before he could take his seat he died, 27 Aug. 1830, following ‘a short illness, which terminated in a typhus fever, supposed to have been occasioned by the fatigue and anxiety attendant on the election’.
