On his uncle's death in 1739 he inherited a fortune, and in that year he purchased from Sir Richard Child, Earl of Tilney, the estate of Henley Park, in the parish of Ash, near Guildford, which remained his property until 1785.
The originals were bought from the heirs of Dayrolles by Messrs. Bentley, and they then passed by purchase to Mahon (by then Lord Stanhope) in April 1846.
He married, on 4 July 1751, Christabella, daughter of Colonel Peterson of Ireland, who is said to have been 'a lady of accomplished manners and dignified appearance.'
She died at George Street, Hanover Square, on 3 August 1791; her age at death is given as 58, so that she must have been considerably younger than her husband.
Emily married, on 24 December 1786, the Baron de Reidezel, aide-de-camp to the Duke of Würtemberg; and Mary became the wife, on 6 February 1788, of Richard Croft, junior, a banker in Pall Mall.
