When Anderson Pelham’s father succeeded as 2nd Baron Yarborough in September 1823 he wished Gilbert John Heathcote* to replace him as Member for Lincolnshire, but on his refusal he brought forward Sir William Amcotts Ingilby in order to keep out Sir Robert Heron*. According to Emelia Boucherett, Yarborough hoped that Amcotts Ingilby ‘could easily be turned out when young Pelham came of age’, but in the event he proved a popular Member and sat undisturbed. Anderson Pelham was returned for the family’s pocket borough of Newtown at the 1830 general election, when he was only just of age. He later told the Lincolnshire freeholders that ‘not only was there no chairing at my electing, but I was never at the borough in my life’.
With other county Members, he took some interest in the progress of the Fordingham drainage bill in June and July 1831.
At the 1832 general election Anderson Pelham topped the poll for North Lincolnshire. He sat there as a Liberal until his succession to the peerage in 1837, in which capacity he acquired the epithet ‘Yarborough the Good’.
