Military records are a valuable source of genealogical information—one of the best! Military service records, bounty land files, and pension files are some of the more commonly used in this record group, but don’t stop there. Draft cards, discharge papers, prisoner of war records, veteran cemeteries, soldier homes, and veteran/lineage societies can be rich resources for the researcher.
Do you know if your ancestor served in the military? The FamilySearch Wiki provides an Ages of Servicemen table to help determine this. From this table I created the Table of Wars – Ages of Servicemen downloadable cheatsheet with a timeline of wars servicemen might have been involved with, according to their birth dates at the time of the conflict. This is a table for wars the United States was a part of, but since most of these wars involved foreign countries, it can be a helpful tool for your foreign-born ancestors, as well.
We tend to think of wartime service for veterans, but don’t forget that men and women served in peacetime, too. Use this cheatsheet to determine if your ancestor might have been part of a military conflict, and then check the FamilySearch Wiki for search strategies specific to each war.
