William inherited the estate, passing it in 1739 to his son Charles. It was Charles Gore who was responsible for diverting the main Aylesbury to Berkhamsted road from its existing course through the park, which took it straight past the front door of the mansion, to its present route, following considerably flatter terrain further north along the course of what has now become Tring High Street. The property passed through two further generations of the Gore family before being sold to Sir Drummond Smith, a London banker, in 1786. He made extensive changes both to the park and the house, which until that time had remained unaltered from Wren's original design. The contours of the parklands were smoothed and flattened to present a more naturalistic outlook in keeping with the style of Capability Brown that was in vogue at the time and the interior of the house was extensively remodelled along the entire south range of reception rooms with the exception of the library, which retained its seventeenth century ceiling. The drawing room and sitting rooms were given moulded and carved plaster ceilings in the rococo style, complete with cherubs and garlands.

William Kay's son inherited the house in 1838 and it was from this time that Lionel de Rothschild began renting it as a summer home. The Rothschilds When the Kays decided to sell in 1872, Baron Lionel de Rothschild bought Tring Park and its , which also included the manors of Miswell, Hastoe, Dunsley and Willstone for £230,000 – this equates to about £8,000,000 in today's money. Lionel gave the property to his son, Nathaniel Mayer Rothschild as an overdue wedding gift. The location was very convenient since he had been Member of Parliament for Aylesbury since 1865 and the Rothschild family had also acquired a number of estates in the area. In 1872 the family moved to Tring with their son Walter Rothschild, aged four; their daughter Evelina and second son Charles Rothschild were both born at Tring. The family divided their time between their London home at 148 Piccadilly and Tring Park. Lady Rothschild preferred to remain at Tring with her children throughout much
