Eugene was in WW1 and on his attestation form gives next of kin as father Alphonse of Callander. There is nothing to say he was killed in the war. Signed up 1916.
1911 is the last census released.
It doesn't give any cause of death for Cleophus.
Alice Robert married 7 March 1914 to Bernard Ambrose Matthews. She was living in Astorville and mother was still alive.
Eva married 13 Oct 1911 to Edmond Landry. She was living in Haileybury.
I don't see a death for Alphonse or Delima.
