Start With Family Clues
Before diving into archives, check what you already have at home. Old letters, photographs, medals, diaries, and newspaper clippings can provide hints about military service. Even stories passed down through generations—like “Great-Grandpa went off to fight in Europe”—might point to enlistment or deployment. Look closely at uniforms or insignia in photos; they can reveal a regiment or rank.
Explore Draft and Service Records
Official military records are essential for confirming service. In the United States, the National Archives houses draft registration cards, service files, and pension records. Draft cards often include birth dates, addresses, and occupations, even if the person never served overseas. Other countries have similar archives: the UK’s National Archives, Library and Archives Canada, and Australia’s digitized World War I records are excellent places to start.
Check Newspapers and Obituaries
Local newspapers from the World War I era can be surprisingly detailed. Many printed lists of enlistees, letters sent from the front, or reports on local soldiers’ experiences. Obituaries may also highlight military service, battles fought, or honors received. Online newspaper databases and archives make this research easier than ever.
Look for Medals and Regimental Histories
If your family has medals or ribbons, they can provide clues about campaigns or service periods. Even if the physical medals are gone, military records often list awards and decorations. Regimental histories, available in libraries or online, offer context about where your ancestor served and what their unit experienced.
Connect With Other Researchers
Genealogical societies, online forums, and military history groups are great resources. Sharing your discoveries may connect you with distant relatives or fellow researchers who can fill in gaps in your ancestor’s story.
