Funny the things you stumble across
whilst looking up other things.   

In search of a poem/song-lyric by an Englishman named Salmon,
my online Google searches took me to an issue of
the Winnipeg Free Press, of all things, which had the poem inside.
The date was late November, 1934.
Elizabeth, the Princess, would have been all of eight years of age.
She was amongst the bridesmaids for a wedding that had just taken place,
that of George, Duke of Kent, to Princess Marina.
The Duke would die in a plane crash in Scotland during the war.
Anyway, a chatty description of the wedding includes mention of
"the winsome Princess Elizabeth,
the granddaughter of the king and queen."
