a second dated 1 February 1713 left her an additional £5000 plus his interest in the rangership of Bushey Park and his manor of Apscourt in Surrey to pay for the repairs to Bushey Lodge. On 30 August, however, he revoked the first codicil and begged his executor, his nephew George Montagu, not to make a dispute over her legacies. Montagu wrote that these bequests were "as a token of the sincere love, affection and esteem, I have long had for her person, and as a small recompense for the pleasure and happiness I have had in her conversation". Halifax's official life defended Barton against accusations that she might have been sexually involved with him, stating:as this Lady was young, beautiful and gay, so those that were given to censure, pass'd a Judgment upon her which she no Ways merited, since she was a Woman of strict Honour and Virtue; and tho' she might be agreeable to his Lordship in every Particular, that noble Peer's Complaisance to her, proceeded wholly from the great Esteem he had for her Wit and most exquisite Understanding.Based on the generosity of the bequest, astronomer John Flamsteed wrote, apparently sarcastically and spitefully, that Barton must have "excellent conversation". Marriage Barton then returned to live with her uncle at his home in St Martin's Street. On 9 July 1717 she became engaged to marry John Conduitt who had arrived in England a few weeks earlier in May of that year. On 23 August they were issued a licence to marry at St Paul's Covent Garden, but actually married three days later at St Martin in the Fields. Barton had one daughter with Conduitt, Catherine, who was born in 1721. Later life Barton lived with Conduitt at Cranbury Park, near Winchester. She took in Newton towards the end of his life, and he resided with her until his death in 1727. After Newton's death, his papers were in Barton's care and then passed down through her family until 1936 when they were auctioned at Sotheby's. Conduitt died on 23 May 1737; Catherine died in 1739 and was buried with her uncle and husband in Westminster Abbey. Their only daughter and heir, Catherine, married John Wallop, Viscount Lymington, the eldest son of the first Earl of Portsmouth, and their son, John Wallop, succeeded as second Earl of Portsmouth.
