[3] Feilding served as a lieutenant in the Royal Naval Volunteer Reserve (RNVR) and worked for the British Intelligence Staff in Egypt and Palestine (1915–1919).

[1] Psychical researcher Eric Dingwall wrote that Feilding was a "member of one of the most distinguished Catholic families in England" and was "one of the most acute investigators of alleged supernormal phenomena that this country has ever produced.

Podmore said that the report provided insufficient information for crucial moments and the investigators representation of the witness accounts contained contradictions and inconsistencies as to who was holding Palladino's feet and hands.

Hansel noted that they were performed in semi-dark conditions, held in the late night or early morning introducing the possibility of fatigue and the "investigators had a strong belief in the supernatural, hence they would be emotionally involved.

"[10] Although originally convinced of her alleged powers, Feilding attended séances with Palladino in 1910 with the magician William S. Marriott and concluded her mediumship was fraudulent.

"[12] In 1914, Feilding with Maud Gonne and W. B. Yeats visited Mirebeau to investigate an alleged miracle of a bleeding oleograph that was in the possession of priest Abbé Vachère.

His wife suspected that Vachère sprinkled water on the picture from a small pot she found behind some flowers in the room.

[14] Feilding was a friend of the neurologist Henry Head who he attempted to get involved with psychical research.

[16] He invited Head to a "ghost hunt" at an alleged haunted house known as "Pickpocket Hall" on his brother's estate in Pantasaph.

He wrote in a letter to Wilfrid Meynell that they spent a few nights in the derelict house but the result was a failure.
