Groom of the bedchamber 1767 – 73.
Lord Powis wrote to George Grenville, 28 Aug. 1764,1Grenville mss (JM). on the death of H. B. Legge, that he had secured Lord Portsmouth’s promise not to engage his interest in Hampshire; and added that application had been made to him to recommend Captain Wallop of the Guards for one of the grooms of Prince William’s bedchamber. ‘He is sober and decent in his behaviour; and has a very good understanding; and also a good person.’ Grenville replied that he would attend to the request.2Grenville to Powis, 4 Sept., letter bk. But the King said he would leave his brother a free choice of those ‘to be in that office constantly about his person’.3Grenville to Lord Portsmouth, 12 Nov. 1764, letter bk.
Wallop was returned for Whitchurch on his brother’s interest. There is no record of any vote or speech by him in the House; in Robinson’s two surveys on the royal marriage bill, March 1772, he was listed as ‘pro, absent’; and again as ‘pro’ in the electoral survey of September 1774. He did not stand again for Parliament; and died in August 1794.
