Wilton (1690 - March 4, 1701) Truro (March 5, 1701 - December 1701) Wilton (1702-1705) Hawles was born in the Close at Salisbury, the second son of Thomas Hawles of Moanton in Wiltshire, and his wife Elizabeth Antrobus of Hampshire, daughter of Thomas Antrobus of Heath House, Petersfield, Hampshire.
At the 1702 English general election he was returned in a contest as MP for Wilton again, but lost his place as solicitor-general.
He was returned in a contest as Whig MP for Stockbridge at the 1705 English general election and voted for the Court candidate as Speaker on 25 October 1705.
He was passed over for office and may have expressed his resentment by speaking against the Court on the treasons trial bill on 5 April 1709.
Nevertheless, he was appointed as one of the managers of the impeachment of Henry Sacheverell in 1710 but offended his fellow Whigs by giving way on several points.
