John Hardman was the son of Richard Hardman, merchant, of the manor of
Rochdale, by his wife Elizabeth Fernyside. His brother,
James Hardman (c.1692–1746) was also a slave trader and married to Jane Leigh (painted by
Joseph Wright of Derby). The Hardmans were an old
Lancastrian landed gentry family. While some contemporaries described Hardman as a mere 'West India merchant', A slave ship-owner, he was said to have had considerable knowledge of African and American trade. He inherited the estate following his brother's death in 1746. Hardman regularly gave evidence to the
Board of Trade on behalf of the Liverpool Corporation. He had also organised a survey on behalf of the Liverpool merchants of the possibility of a canal to join the rivers
Trent and
Mersey. In 1754, he was elected as a
member of Parliament (MP) for
that constituency, but died the following year on 6 December 1755. == Appearance ==
