In a more formal setting she was admired by many for her soprano voice of unusual compass, but at the Queen's Hall in London in 1922, Parbury's programme of operatic excerpts and drawing-room "trifles" did not impress a music critic from The Times.

[6] Parbury also described[7] how she flew over Stonehenge in a biplane piloted by Howard Pixton, an early British aviator who won the 1914 Schneider Trophy air race held in Monaco.

After her visit, Parbury wrote to him several times in late 1912 and early 1913 saying that she would "so like to reproduce a photograph of that interesting case of curios & Indian trophies & relics, for my book."

Miss Parbury does not actually shoot big game, but like her friend, Mr. Thompson Seton, she enjoys the call of the wild and the tracking of shy creatures to their lairs.

Without publicity up to the present, she has obtained 75,000, thanks to the contributions of Sir John Thornycroft, Mr. Harry Gratton, Mr. Gerald du Maurier, Mr. Henry Ainley, and others.

[13] Back in London, Parbury set up a "Jacobean studio" at Yeoman's Row, Knightsbridge where she and others would entertain wounded soldiers with sing-songs.

[13][14] In an interview in Montreal after the war she said "I know of three cases where sight, hearing and speech were restored while an entertainment was in progress, to men who had lost three senses through shell shock.

[15] On another occasion, hearing that Sir Robert Borden, Prime Minister of Canada, was in London she immediately wrote[16] to seek his patronage for a matinée at the Queen's Theatre in aid of the Canadian Red Cross, which Canadian soldiers would attend; Sir Robert's successful visit, during which he honoured the men and their dead comrades for their sacrifices, was recorded in The Times.

[19] After staying with the Governor of Newfoundland, Sir Alexander Harris, in St John's, as "part of a well-earned post-war vacation", Parbury returned to New York where she had portraits taken by the renowned photographer Arnold Genthe .

At the end of the year, "garbed as a Maharani", she spoke at a meeting of the American Geographical Society in New York on "Kashmir, the Garden of the East".

[23] This circuit, which included stops in Decatur, Chicago, Dayton and Detroit, gave her more opportunities to promote her League of Friendship idea, which she also referred to as a Friendship Club for Anglo-Saxons: "I want to have a beautiful clubhouse in every large city around the world where the English-speaking peoples can meet..." In 1921, Parbury was in Washington DC, where she announced that she had two books coming out in the fall, "Careering in Canada” and "Atmosphering in America.” They were to be published in practically the same form, with her own illustrations, but never appeared.

[19] When the new British Ambassador to the United States, Sir Auckland Geddes and his wife, arrived from Liverpool on the Kaiserin Auguste Victoria in 1920 "Miss Florence Parbury welcomed him to America by flying over the ship in an airplane to drop a bouquet of American Beauty roses."

[25] Later that year Parbury was a passenger on one of the escort aircraft when three all-metal planes were seeking the best route from New York to San Francisco; a transcontinental air mail service was established in September 1920.

[26] Back in England, there was another aviation adventure: in January 1922 Parbury flew as a passenger to the Hague, with a Blackburn test pilot,[27] while using wireless telephony to listen to one of her own compositions being played in a hall below.

[31] The couple lived at Ernest's home: Scote Howe, Hook Heath, Woking, Surrey, where Florence enjoyed growing specimen flowers for exhibition.
