On the death of the eleventh Baronet in 1899 the house passed to his daughter, who had married Thomas Lamplugh Wickham, and who had adopted the additional surname of Boynton. On her death it passed in turn to their son Marcus Wickham Boynton, who operated a successful stud farm on the estate for many years and was High Sheriff of Yorkshire for 1953–54. He died in 1989 and left the property to a distant cousin, Simon Cunliffe-Lister, then aged twelve, grandson of Viscount Whitelaw and son of the 3rd Earl of Swinton. Today, the estate is owned by the Burton Agnes Preservation Trust and is managed by Cunliffe-Lister and his mother, the Hon. Dame Susan Cunliffe Lister DCVO.
