military recordsThe uses and significance of Colorado military records in family history and genealogical research for ancestors that were veterans are obvious but Colorado military records can also be essential to researchers whose primary ancestors weren’t soldiers in any war. Because of the volume of genealogical facts contained in a number of Colorado military pension files they ought to never be disregarded during the research process.

National Guard muster rolls for 1861 to 1919 can be found at the Colorado State Archives. Service records for the Colorado National Guard from 1861 to 1945 are also located there. The “Index to Compiled Service Records of the Union Army for Colorado” can be found on microfilm at the offices of the Adjutant General. The FHL, Denver Public Library, and National Archives-Rocky Mountain Branch also has that index on file. The recorder’s office or county clerk’s office should have post-World War II soldier discharge papers on file. However, some counties are closing the discharge papers to researchers.
