Horsham
The Ingram family, Viscounts Irwin, acquired an influence in Horsham in the early 18th century which in 1737 they converted into control.This article is based on W. Albery’s Parl. Hist. Horsham, chs. VI-X. This was unchallenged for some 50 years, but about 1787 the Whig 11th Duke of Norfolk, who had lately succeeded, decided to build up his influence as lord of the manor.
