Hartopp, whose father had represented Leicestershire, 1798-1806, assumed the additional name of Fleetwood in acknowledgement of his lineal descent from the Cromwellian General Charles Fleetwood (d. 1692), whose estates had devolved on his mother. At Oxford he was considered an ‘elegant scholar, and of studious turn of mind’.
Hartopp died intestate and v.p. at Mitcham, Surrey in March 1824, having taken ‘cold during his parliamentary attendance’ from ‘want of attention to warm clothing’. His estate and ‘funded goods’ passed to his father.
