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
If you want to check the CEF site to see if your relative is there, go to the Library and Archives Canada site to see if they are listed as having joined. The site is http://www.bac-lac.gc.ca/eng/pages/home.aspx
If I can be of any assistance to you in researching your CEF member, you can email me at email@example.com or visit my site at http://www.elrs.biz
