With many thanks to members of the Remembrance Group for Canadian servicemen. I have now found three Canadian poets and will add them to the list -
R.M. Eassie (1875 - 1940) born in Hendon, England;
William Maunsel Scanlan (1886 - 1917) born in Port Elgin, Ontario and
Frederick Bertram Bagshaw (1875 - 1966) born in Southport, England.
Scanlan was killed at Vimy Ridge on 9th April 1917 - the same day my Great Uncle was killed at Arras. The British poets Edward Thomas and R.E. Vernède were also killed on Easter Monday, 9th April 1917.
