RE: William John Walter McCallum It's fairly easy. Go the main page of the Vimy Memorial and click on "Add a name to this cemetery" and fill in the info. I always gather the info from the Canadian Virtual War Memorial. https://www.findagrave.com/cgi-bin/fg.cgi?page=cr&CRid=1119613&CScn=vimy+&
RE: William John Walter McCallum Thanks for the note. The photo has been deleted. There should be two memorial pages. One for each William but there is no memorial page for your William McCallum. Why don't you create one.
