Military Records in Genealogy: Service, Pension, and Muster Rolls

Why Military Records Matter

Military records are some of the most detailed and personal documents any genealogist will encounter. A parish register gives you a name and a date. A census gives you a household snapshot. But a military pension file can give you a life story: where a man was born, when he enlisted, where he served, what wounds he suffered, who his wife was, when and where his children were born, what his health was like in old age, and how he died.

The reason is simple. Military bureaucracies need information to manage personnel, and pension systems need information to verify claims. The result is a paper trail that can span decades and contain dozens of documents -- enlistment papers, muster rolls, hospital records, discharge papers, pension applications, supporting affidavits, and correspondence.

For American genealogy especially, military records are indispensable. From the Revolutionary War through the twentieth century, military service generated records that are often the richest source of family information available for a particular ancestor.

Service Records

Service records -- also called compiled military service records (CMSRs) for US conflicts before World War I -- document an individual's military career: enlistment date, unit assignments, promotions, hospitalizations, disciplinary actions, and discharge.

For the Revolutionary War (1775-1783), service records are fragmentary but significant. Continental Army records, state militia records, and bounty land warrants survive for many soldiers. The National Archives holds compiled service records and pension files.

For the Civil War (1861-1865), service records exist for approximately 6.3 million Union and Confederate soldiers. The compiled military service records include muster rolls, casualty sheets, prisoner of war records, and hospital records. Union records are held at NARA; Confederate records are split between NARA and state archives.

For World War I, most US Army service records were destroyed in the 1973 fire at the National Personnel Records Center in St. Louis. Approximately 80 percent of Army records for personnel discharged between 1912 and 1964 were lost. This is one of the great archival disasters of American history. Draft registration cards, however, survive for virtually all men aged 18-45 in 1917-1918, providing name, birth date, birthplace, physical description, occupation, and next of kin.

For World War II, service records are available through NARA (for deceased veterans) and through a request process (for living veterans or their next of kin). The WWII Army Enlistment Records database, available through NARA, provides a searchable index of approximately 9 million enlistment records.

Pension Records

Pension files are the genealogist's treasure. They contain far more information than service records because the pension application process required the veteran (or his widow) to prove identity, service, disability, and family relationships.

A typical Civil War pension file contains:

The application: Name, age, residence, unit, dates of service, nature of disability or grounds for pension.

Supporting affidavits: Statements from fellow soldiers, neighbors, and physicians confirming the veteran's identity and claims. These affidavits often contain detailed narratives of wartime experiences.

Surgeon's certificates: Medical examinations documenting the veteran's health, wounds, and physical condition -- sometimes in extraordinary detail.

Marriage and family documentation: When a widow applied for a pension, she had to prove her marriage and her husband's death. The file often contains marriage certificates, family Bible pages, birth records of children, and statements from witnesses to the marriage.

Correspondence: Letters between the veteran, the Pension Bureau, attorneys, and others. These letters sometimes contain personal details that appear in no other record.

Revolutionary War pension files, available through Fold3 and FamilySearch, are similarly rich. The pension applications submitted in the early nineteenth century often contain detailed narratives of service, recorded decades after the events, providing firsthand accounts of the war.

Muster Rolls and Unit Records

Muster rolls -- the periodic counts of a unit's personnel -- document who was present for duty, who was absent, and why. They are particularly valuable for tracking an ancestor's movements during wartime.

For the Civil War, muster rolls were typically compiled every two months. Combined with regimental histories (many of which have been published), they allow you to follow a soldier through his unit's campaigns, knowing where he was at specific dates and what battles his unit fought.

Unit records -- order books, morning reports, after-action reports -- are held at NARA and some have been digitized. Regimental histories, published by veteran organizations in the decades after the war, often include rosters of personnel with biographical details gathered from surviving members.

British and Scottish Military Records

For researchers with British or Scottish ancestry, military records are held primarily at The National Archives (Kew) and the National Records of Scotland.

British Army service records for World War I (the "burnt documents" and "unburnt documents" in series WO 363 and WO 364) survive for approximately 40 percent of soldiers who served. The rest were destroyed by German bombing in 1940. The surviving records have been digitized and are available through Ancestry and Findmypast.

For earlier periods, the records are more scattered. Muster rolls and pay lists for the British Army survive from the eighteenth century. Chelsea Hospital pension records (for army pensioners) and Greenwich Hospital records (for naval pensioners) contain detailed personal information.

Scottish regimental records -- the Black Watch, the Seaforth Highlanders, the Gordon Highlanders, and others -- are held at the National Records of Scotland and regimental museums. For Highland Scots who served in the British Army (and many did, particularly after the Clearances removed other options), these records can provide detailed biographical information.

Getting Started

NARA (archives.gov) is the starting point for US military records. Many records are available online through Fold3, Ancestry, and FamilySearch. Physical records can be requested by mail or in person at NARA facilities.

The National Personnel Records Center (NPRC) in St. Louis handles requests for twentieth-century service records using Standard Form 180.

Fold3.com (a subsidiary of Ancestry) specializes in military records and has extensive digitized collections of service records, pension files, and unit records.

Military records require patience -- pension files can run to hundreds of pages, and the handwriting ranges from legible to illegible. But the reward is a depth of detail that no other genealogical source can match. In a pension file, you do not just find your ancestor. You meet him.
