If you had anyone in the Canadian Expeditionary Force during the First World War, you should read this notice -
To commemorate the 100th anniversary of the start of the First World War, OGS has launched a new Heritage Society. The First World War Society is a lineage Society open to anyone who can show descent from a person who served in a documented capacity on the Allied side of the First World War.
To qualify for this Society, your research must show that your named ancestor(s) fits in the category above, and then show the line of descent from that ancestor(s) to you or the person you wish named on the certificate.
For more information and an application form visit the Heritage Societies area on the OGS website is http://www.ogs.on.ca/heritage_societies.php#WW1
