Lord Haversham died on 10 May 1917. Lady Haversham was still in residence in 1920 when she erected a marble tablet in Easthampstead Parish Church as a memorial to 62 men who lost their lives in the 1914–18 war. After the death of Lady Haversham in 1929, leaving no direct heir, the house passed into the hands of Major Rickman O.B.E., Lady Haversham's nephew, who was the last person to own and live in it as one house and is best known for shooting himself in the Gun Room in 1940.
