Bart, I understand. Please note that for consistency I list the names of the soldiers as they are recorded at the LAC. I then make a note in the page if I am made aware of a different name. This man signed LEGAL documents with both spellings. That is irrefutable. He accepted the spelling the Canadian Army used or he would or could have requested a correction to his records. Thank you for making me aware of this spelling.
