Writing in 1877, the last Cornish historian remarks that the condition of Tregony had passed from bad to worse. Many of its houses were then in ruins, and the scene of desolation was spreading. In early times Tregony had been a seaport on a tidal creek, but that was silted up, and no boat could now reach it, so that its commercial importance was wholly gone.

During the eighteenth century the representatives of Tregony were men of little importance, small placemen unconnected with Cornwall. In the long array of aliens and Court satellites, the name of one Cornish gentleman stands out in bright relief; 1747-67, for twenty years (a long period) Mr. Trevanion represented it. The election of 1774 excited much notice. Lord North advised a note to be written to Lord Falmouth: "His Lordship must be told in as polite terms as possible, that I hope he will permit me to recommend to three of his six seats in Cornwall. The terms he expects are £2000 a seat, to which I am ready to agree." Later on, he says that his candidate Pownall must get in for Lostwithiel, and Conway represent Tregony, and he added: "My noble friend (Falmouth) is rather shabby, desiring guineas instead of pounds," but signified his will to pay rather than drop the bargain. Again: "Gascoyne shall have the refusal of Tregony for £1000," and the Minister complained that he saw no way of bringing him in at a cheaper rate than any other servant of the Crown.

In 1776 the Boscawen influence was sold to Sir Kit Hawkins, but he did not retain it for long, for he disposed of it to a Nabob, Barwell, and the two continued on friendly terms. When the living of Cuby fell vacant—Cuby is the parish church of Tregony—Sir Kit asked Barwell, who now had the presentation, to give it to a friend of his, alleging that "he had great interest" and assuring Barwell that his clerical friend would reside in the place, and by his great activity in the borough prevent, if possible, any opposition arising to Mr. Barwell. But at the very next election Sir Kit ran and returned two members against Barwell.

In the contest of 1784, Lord Kenyon, a lawyer, obtained the seat by purchase, polling 90, while his two opponents got 69 each.

In 1806 an O'Callinghan and a Yorkshire Whig, through Darlington's interest polled against Barwell's interest 102 against 86. At this election the following trick was played. A Tregony tailor and publican, called Middlecoat, offered to seat Sir Jonathan Miles for 4000 guineas. At the poll the returning officer, who was biased or had been tampered with, struck off many good votes from Miles, and gave bad ones to others. Sir Jonathan petitioned and, for the expenses of the petition, sent Middlecoat a large sum of money, and he prevented the witnesses from appearing, and the sitting members were accordingly pronounced to be duly elected. Middlecoat had secured £2500 from the sitting nominees (Barwellians) to keep back the witnesses, as well as £4200 from Sir Jonathan to bring them forward.

In 1812 O'Callinghan was unseated, and petitioned, showing that £5000 had been distributed among the voters; nevertheless the sitting members were received. Holmes, one of them, said—to show what was the degraded condition of the borough—that out of 127 votes in his favour, 98 had been evicted into the street the day after the election, some having been called on to pay their rents, but were unable to do so at the moment, and others, whose annual rents were only £8, had been mulcted in costs to the extent of £98.

Middlecoat, and four others of like spirit, went to London in 1818 to search for candidates for Tregony and Grampound, offering the former for £6000 and the latter for £7000. A banker and a general came down before the election, but found that the voters would make no promise unless the money were paid down. So they had to return to London "proclaiming their disappointment at every turn, and cursing the scoundrels who would not trust them."

Christopher Hawkins was returned for Mitchell in 1784, re-elected in 1790 and 1796. In June, 1799, he vacated his seat by accepting the Stewardship of the Chiltern Hundreds. In August, 1800, he was elected for Grampound, again in 1802 and 1806. In 1818 he was returned for Penryn, and in June, 1821, for S. Ives. He was created baronet on July 28th, 1791. He was Recorder of Grampound and S. Ives and, at the time when he relinquished his seat finally, he was the father of the House of Commons.
