The Chaloners were neighbours of the Dundas family, whose principal residence was at Aske, but who had a second house at Upleatham, only two miles from Guisborough. Chaloner’s cousin Harriot Hale married Lord Dundas’s eldest son Lawrence Dundas in 1794. Chaloner himself married Dundas’s daughter in 1805 and was returned for his borough in 1810. He had been proposed for Brooks’s in 1805 by Earl Fitzwilliam and was classed ‘present Opposition’ by the Whigs in 1810, but his attendance was relatively infrequent and no speech is known. His first recorded vote with opposition was on Lord Chatham’s conduct over the Scheldt expedition, 5 Mar. 1810. He re-emerged to oppose Perceval’s motion for a fortnight’s adjournment, 15 Nov. 1810, and was in the minority on the Regency, 21 Jan. 1811. He did not appear again in the division lists until Morpeth’s motion on Ireland, 4 Feb. 1812, after Lord Milton had written to Lawrence Dundas urging attendance.
Chaloner returned to the House in 1820 as Member for York, where in 1818 he had acted on behalf of Fitzwilliam and Lawrence Dundas and had shown interest in extending the Whig representation to both seats.
