Born into a wealthy Southampton banking dynasty, which he was content to let his younger brother George (1782-1856) manage, Atherley had sat intermittently for that borough prior to 1818 with the support of his father, the town’s mayor in 1783 and 1797, before making two unsuccessful bids to come in for Arundel, where he was resident.
A fairly lax attender, evidently in frail health, when present Atherley gave steady support to the Whig ministry on most major issues, including their Irish coercion bill, 6 Mar. 1833, and Irish church bill, 21 June 1833, and was in their majorities against radical motions for inquiry into agricultural distress, 21 Mar. 1833, shorter parliaments, 23 July 1833, and a lowering of corn duties, 7 Mar. 1834. He was absent, however, from divisions on the ballot, 25 Apr. 1833, inquiry into the pension list, 22 Feb. 1834, and naval impressment, 4 Mar. 1834, and was ‘prevented by ill health’ from taking his place on the London and Southampton railway committee, 17 Mar. 1834.
Atherley died in October 1844 at Arundel, where he was a ‘liberal benefactor’ to the poor.
