Inside St Andrew's there is a moving memorial to Edward, heir to the estate, who died of his wounds and is buried in France. A bronze equestrian statue by Sir Alfred Mannings depicts Edward. The plinth on which the statue rests was designed by Sir Edward Lutyens and is a smaller version of the cenotaph in London.


On the south wall of the church there is a memorial to Raymond Asquith, the son of the Prime Minister, who also died of his wounds in France during the Great War.
The churchyard contains a number of famous English names apart from the Asquiths and Horners. There are members of the Bonham-Carter family and the poet Siegfried Sassoon is buried here.
