Canadian Military Records - O'Sullivan

Discover the military hero in your family with Ancestry.ca. With millions of military records from around the world, Ancestry.ca can help you find the military history in your family.

When researching in military records, it is helpful to determine when and where in the armed service a soldier served, and whether he or she was in the enlisted ranks or an officer. Clues may be found in family stories, old newspaper clippings, correspondence, scrapbooks, journals or diaries, service medals and memorabilia, and photographs of the soldier in uniform. The grave marker of a veteran may contain information about military service as well. Military records may have been created in peacetime or during time of war, depending on the record type, and you may even find military records for ancestors who never served.


Ancestry.ca has 59 records, showing 12.
