As I’ve been reviewing the annual report of the Toronto Public Library for 1919, the year my grandmother Velma Jane Moore began working there as a cataloguer, much was made of the Reference Department’s role in preparing the City of Toronto for a state visit by the Prince of Wales:
. . . no day passed that we should have to wrestle with problems such as: The correct way to address the Prince of Wales; the meaning and the origin of the motto “Ich Dien”; the standard of the Prince of Wales; when flown; his crest and coat of arms; the flag of the Prince of Wales in color; a portrait of the Prince of Wales in his trench coat; the words of the song “God Bless the Prince of Wales”; a description of aiguelettes worn by a Naval A.D.C., to send to a Naval tailor for the Prince of Wales’ reception; material on Rear Admiral Halsey (Chief of Staff), account of the Prince of Wales’ (King Edward) visit to Canada in 1861, etc., etc.1
Let’s see how well I can do with Google:

An account of the Prince of Wales’ visit to Canada in 1861 can be found in Chapter II of H.R.H, the Prince of Wales: an Account of His Career, including His Birth, Education, Travels, Marriage and Home Life; and Philanthropic, Political, and Social Life by Marie Lowndes, published in 1898 by Grant Richards of London. (Retrieved from Hathitrust 1/10/2019. )

Biographical material on Rear Admiral Lionel Halsey can be found in Chapter IX of Admirals of the British Navy: Portraits in Colour by Francis Dodd, published by the Offices of “Country Life,” LTD in 1917. (Retrieved from Internet Archive 1/20/2019.)

The lyrics to “God Bless the Prince of Wales” can be found in the program for the 1882 Christmas Music Festival held at Christ Church Cathedral in Montreal. (Retrieved from Internet Archive 1/20/2019.)
I found answers to the other questions as well, but the sources were dated after 1919 or located in online archives with no original source listed, so I didn’t include them. I wouldn’t want to have an unfair advantage over our doughty band of reference librarians!
And now, for a historical oddity found along the way:

Photograph appears in The Prince of Wales’ book: a pictorial record of the voyages of H.M.S. “Renown” 1919-1920, published by Hodder & Stoughton, LTD, 1921. (Retrieved from Internet Archive 1/20/2019.)
And a mystery to be solved!
I found this invitation to meet the Prince of Wales in The Family Archives. Ronald Dalrymple Brown was my maternal grandfather. (He and Velma married in 1926.) At the time of the invitation to meet the Prince of Wales, Ronald was a student at the Massachusetts Institute of Technology. The only connection I can see between him and the reception to meet the Prince is that it was held in New Brunswick, and Ronald’s mother was originally from New Brunswick. However, that seems like an extremely tenuous connection. Figuring this one out is going to take some doing!
