[1] The church has close connections with the local Asquith family and the Horners who lived at Mells Manor.

Interments include: the poet Siegfried Sassoon;[2] the priest, Ronald Knox;[3] politician Sir Maurice Bonham Carter,[4] the novelist George A. Birmingham aka James Owen Hannay,[5] and Katharine Asquith, widow of Raymond Asquith.

The quality of the statue led to a commission from the Jockey Club for Munnings to create a bronze of the racehorse Brown Jack;[7][8] a bronze wreath designed by Sir Edwin Lutyens, who also designed the Mells War Memorial, with lettering by Eric Gill, to Raymond Asquith;[9][10] a bronze plaque to Captain Stanes Geoffrey Bates of the 7th Queen's Own Hussars, killed in action near Ypres in the First World War; and a white gesso plaque of 1886 by Edward Burne-Jones to Laura Lyttelton.

Burne-Jones created a gilded copy of the memorial which is in the Victoria and Albert Museum.
