The Tichborne and Doughty period. 

Edward Doughty, who had been born Edward Tichborne, bought the House and Estate in 1828. Edward was the third son of Baron Tichborne of Tichborne Park, one of the oldest and richest families in Hampshire. Edward and his wife, the former Kathryn Seymour, were a quiet catholic family, never very well known in Poole. In 1834 their only surviving child, Kathryn was born at Upton.

 Like his brother James, the fourth son of the Baron, he had an allowance of £500 a year, and Edward had started out life working on the Duke of Buckingham's sugar plantations in Jamaica until, in 1826, to the astonishment of the whole family, he was left the wealth and estates of a fourth cousin named Elizabeth Doughty, on condition he took the name "Doughty" in the hope that he would have a son and continue the Doughty line. It was therefore important to start the new county family to have an appropriate house and estate. Aged 46, he arrived at Upton, built extensions to Upton House including the provision of a family chapel in the east wing. He brought with him a negro named Andrew Bogle whom he had brought back from Jamaica. Andrew married a Poole girl named Elizabeth Young, and she worked at Upton House as nurse with Mrs Doughty. 

Edward Doughty will be remembered for providing the coach to take the exiled King Charles the tenth of France from Poole to Lulworth Castle in July 1830, and again when he sailed from Hamworthy for Scotland.  Mrs Doughty's brother, Henry Seymour, became MP for Poole, and always stayed at the London Hotel in Poole's High Street, but never set foot in Upton House, and was to take a prominent part in the misfortunes of his brother-in-laws family in later years.

Following a serious illness, young Kathryn survived, and in gratitude to God for her safe recovery, Edward had the first catholic church built in West Quay Road, Poole, and which could be seen by Mrs Doughty as she sat in the Drawing Room at Upton. At this time the railway had yet to be built, and there was an unfettered view across Holes Bay with Doughty's Island on the left. Today the site is occupied by the Royal National Lifeboat Institute head office.
