He shared a house with his brother Leonard Whibley, William Ernest Henley, and George Warrington Steevens.

In Paris Whibley moved in symbolist circles with Stéphane Mallarmé, Marcel Schwob, and Paul Valéry.

In 1896 Charles married Ethel Birnie Philip in the garden of the house occupied by James McNeill Whistler at n° 110 Rue du Bac, Paris.

The photographs of the wedding were taken by Louis Edmond Vallois,[13] who had a studio at 99 rue de Rennes, Paris.

[19] It was an open secret that Whibley contributed anonymously, to the Magazine, his Musings without Methods for over twenty-five years.

[20] Whibley died on 4 March 1930 at Hyères, France, and his body was buried at Great Brickhill, Buckinghamshire.

[8] A portrait of Charles Whibley (1925–26), by Sir G. Kelly, is held by Jesus College, Cambridge.
