The Ingram family, Viscounts Irwin, acquired an influence in Horsham in the early 18th century which in 1737 they converted into control.
For the next 16 years Norfolk put up no opposition and Lady Irwin’s nominees, most of whom purchased their seats, were returned unopposed. By 1804, her interest was managed by her son-in-law, Lord William Gordon, whose influence may perhaps account for the succession of Scots returned from 1790 to 1802.
The story of 1806 was repeated at the next general election a few months later: the same number of votes being cast on each side as before, the ducal nominees were returned. Lady Irwin’s, who had agreed to pay 4,000 guineas for their seats, petitioned: the election committee upheld them, so reversing the previous year’s decision, again in favour of ministerialists. The committee decided that ‘evidence of rent ... ought to appear in order to constitute a burgage tenement’, and accepted as evidence the poll book—a mere copy of the voters’ conveyances. Romilly, thus unseated, lamented: ‘The committee ... which had decided all the questions raised by counsel in favour of the sitting Members, finally decided against them upon a question of law, which had never been insisted upon by counsel for the petitioners and which was quite incapable of being supported’—no manor court having been held recently enough to apportion the rents in question.
Between 1790 and 1806 Norfolk spent £14,500 on his efforts to gain control. Lady Irwin died in 1807 and Lord Hertford, husband of her eldest daughter, inherited her estates. In 1810-11, after more than two years’ negotiations,
