Petworth was therefore transformed and expanded to become the permanent home of the family with grand stables erected and a pleasure garden laid out at this time. A part of this era manor house, a 'Lost' North wing, was discovered during archaeological excavations in 2012-15 under the lawn at the front of the house having been demolished in 1692. Baroque House In 1670 Josceline Percy, 11th Earl of Northumberland (1644-1670) died without a male heir, and thus his considerable fortune and estates of Petworth House, Alnwick Castle, Syon House and Northumberland House were inherited by his 2-year-old daughter and sole-heiress, Lady Elizabeth Percy (1667-1722).

Split Inheritance challenges and Capability Brown Since 1750 the house and estate have been owned by the prominent Wyndham family, descended from Sir Charles Wyndham, 4th Baronet (1710-1763) of Orchard Wyndham in Somerset, a nephew and co-heir of Algernon Seymour, 7th Duke of Somerset (1684-1750). As part of the inheritance and splitting-up of the great Percy inheritance, which had been a source of contention between the 7th Duke and his father the 6th Duke, in 1749 after the death of the 6th Duke, King George II granted the 7th Duke four extra titles in the peerage, including Baron Cockermouth and Earl of Egremont, which latter two were created with special remainder to Sir Charles Wyndham, the
