Harwell probably hailed from Staffordshire, as he had three sisters who lived in Wolverhampton.
By 1624, when he first represented Coventry in Parliament, Harwell was one of the city’s wealthiest and most prominent residents.
By late 1626 the Coventry drapers, now under Walden’s leadership, were again at the centre of controversy, this time through a protracted dispute with the city’s weavers. In November that year Harwell was appointed by the Privy Council to help investigate the weavers’ complaints. The inquiry dragged on into the following autumn, with Walden employing underhand tactics to influence its outcome. By the time the final report appeared in October 1627, substantially favouring the drapers, Harwell had been dropped as a commissioner.
Harwell died suddenly in September 1629, while serving as master of the mercers for the third time. No will or administration has been found, but by this time he owned around 200 acres and over 30 houses, mostly in and around Coventry. His eldest son, a minor, survived him less than three years, and the properties passed to the boy’s younger brother, fortunately without the burden of royal wardship. None of Harwell’s descendants are known to have sat in Parliament.
