<p>The leading Derbyshire families were the Curzons, Tories, and the Cavendishes, Whigs. At each of the first three general elections two Tories, one of them a Curzon, were returned unopposed, but in 1734 the Cavendishes gained one seat, after which they shared the representation with the Curzons without opposition.</p>
