John Ivory inherited Lacock Abbey estate in 1714 on the death of his maternal grandfather, Sir John Talbot, and took the name John Ivory Talbot. The following year he entered Parliament as a Tory and served as MP for Ludgershall for 7 years. Later he served as an MP for Wiltshire from 1727 - 1741. His career as an MP was less than distinguished. His entry in 'The History of Parliament: the House of Commons 1715-1754' is brief. It records that he voted consistently against the Government and made only one speech in the House of Commons, against the Quakers title Bill in 1736. It is also noted that he was a possible Jacobite supporter in the event of an uprising against the new Hanoverian king. The last remark in the entry is, however, intriguing and reads:
'In 1735 the mother of his nephew, Thomas, 2nd Lord Mansel, then aged 14, objected successfully to his being made sole guardian of her son because she ‘did not care that Mr. Talbot, whose wife is mad ... and is himself driven to drink, should have the sole management of her son’s education’.
Evidence for these assertions have been sought in the Lacock Abbey archives and is found in the Account Books of the Lacock estate and in the correspondence between John and his wife, with John's brother-in-law, Henry Davenport.
