Willoughby Bertie, 3rd Earl of Abingdon (28 November 1692 – 10 June 1760), of Wytham Abbey, Berkshire and Rycote, Oxfordshire, was an English landowner and Tory politician who sat briefly in the House of Commons in 1715.
[1] The Berties were Tories, with a strong electoral interest in Westbury, where the Earls of Abingdon were lords of the manor.
[3] The return for Bertie and Annesley was initially accepted on 28 March 1715 and they were declared elected, but on petition, a number of their voters were disfranchised, and Evans (who had since been created Baron Carbery) and Allanson were declared elected on 1 June.
He remained a staunch Tory, as he declined to join the Oxfordshire association in defence of the Hanoverian succession during the Jacobite rising of 1745.
He and his wife had nine children: In 1764, the trustees of his estate sold some of his manors in Oxfordshire: Wendlebury to Sir Edward Turner, 2nd Baronet,[5] and Chesterton to George Spencer, 4th Duke of Marlborough.
