My siblings and I have been trying for years to research our paternal grandfathers birthplace. He was supposed to have been born in Germany but became a Canadian citizen and fought in the First World War with the CEF. We have applied to the Canadian government but because we do not live in Canada and my surname is not the same I have been unsuccessful. I would be grateful if you could advise me as to my options. I have been on their website but the database does not open.Olive Tree Genealogy responds: Linda, I'm sure it was just a typo but the word should be "naturalization". The first thing you should do is check the online CEF (Canadian Expeditionary Force) database for World War 1 Soldiers. Library and Archives Canada is busy digitizing all the personnel records but even if Leo's has not been completed you will still be able to view his Attestation form.
Because there were several Leo Mason names (and variants) on the CEF database I asked Linda for more details. She replied
His name was Leo William Mason birthday 5/8/1880. He married our grandmother Elizabeth Marion Newington on 4/4/1911 in Stonewall. He died in Vancouver on 26/5/1955. He remarried in 1932 without divorcing our grandmother who had returned to England with our father in 1922.Linda added that she thought he put Ohio on his Attestation papers because he was afraid to put Germany. I am not sure I believe that but she needs to find other records for Leo (census, vital registrations, etc) to verify his country of birth.
Also an index to Naturalization Records from 1915 to 1951 are online and the full record (if a name is found in the index that is of interest) can be ordered. These records can be searched by name up to 1939. See http://www.naturalizationrecords.com/canada/ for the link
