Research hints and tips

How do I go about researching a...



Getting started

A person’s date of birth and place of birth can be useful starting points, as they help you locate them in census records.

The US government has made its population censuses for 1900, 1910, 1920, 1930 and 1940 available online via and (£/$) The 1950 census is available at The National Archives and Records Administration (NARA) 

UK censuses up to 1921 are also available online at (£/$), and Findmypast (£). You can view censuses from 1841 to 1921 free of charge on site at The National Archives (TNA) and at many libraries and record offices.

Official military records

The National Archives and Records Administration (NARA) holds a large number of official military records. NARA’s Access to Archival Databases contain a large number of searchable records from the Second World War to Vietnam

Fold3 (£/$) carries military records and census records from NARA, Missing Air Crew Reports and photographs from the Army Air Forces, many records are free of charge. The search function encourages you to search by full name.

Service Records

The National Personnel Records Center in St Louis, Missouri, holds service records for all members of the US military who served in the 20th Century.

Members of the public can request records ($) pertaining to any US veteran who separated from the military 62 (or more) years ago including:

  • DD 214/ Separation Documents
  • Official Military Personnel File (OMPF)
  • Replacement Medals
  • Medical and Health Records
  • Burials and Emergency Requests
  • Natural Disaster Requests

Unless you are the veteran or their next-of-kin, records of individuals who left the military less than 62 years ago are subject to access restrictions.

Awards and medals

Eligibility for campaign and service medals is based on set criteria, usually being present in a particular theatre of war within given dates or carrying out a set number of operational sorties.

NARA has digitised Air Force Award Cards for medals issued between 1942 and 1963.

Check the official description of eligibility for each medal. The locations and dates of service recorded on an individual’s service record will indicate if they are entitled to a particular medal.

Award of the Purple Heart was not commonly recorded in service records, as it was regularly awarded on the spot during the Second World War, Korean War and in Vietnam.

For some but not all awards, there may also be a separate citation, which describes the action for which the award was made. Operational records or a published squadron/unit history might provide some details, although the individual may not be named.

Local newspapers often listed awards and achievements of local individuals, many are available at local libraries and archives, or can be accessed via (£/$)

Casualties, deaths and burials

Missing Air Crew Reports (MACR) list flying personnel who were lost on missions. MACRS can be accessed via NARA’s Microfilm Catalog or at Fold3(£/$)

American Battle Monuments Commission (ABMC) lists the names of those who died in conflict and are buried or commemorated overseas.  The Fields of Honor database currently contains online memorials for 34,000 American servicemen of all the forces buried or commemorated at Ardennes, Epinal, Henri-Chapelle, Lorraine, Luxembourg and Netherlands American Cemeteries.

The Department of Veterans Affairs’ National Cemetery Administration’s Gravesite locator provides information on the burial location of veterans interred in National, State and military cemeteries and for those buried with a US government grave marker.

Find a Grave is an online database of grave sites, it will sometimes yield obituaries as well as date of death and burial details.

Local newspapers often provide obituaries and notices of death, many are available at local libraries and archives, or can be accessed via (£/$)

Individual Deceased Personnel Files (IDPF) document the circumstances surrounding an individual’s death, and the disposition of their remains (if known). A small collection is available on the our website. IDPFs can be  also requested from NARA, or with the assistance of independent specialist researchers like Bill Beigel ($)

The Defense POW/MIA Accounting Agency (DPAA), provides information about servicemen and women who are missing in action from past conflicts, and undertakes to provide the fullest possible accounting for them.

African Americans

Many of the resources above can be used to trace information about African American troops who served in the US Army Air Forces.

You can filter NARA’s Access to Archival Database search often using the code 2 ('Negro') in the race/ citizen field to return records relating to African Americans

Black newspapers, like the Pittsburgh Courier often reported about the African American experience of war. Some titles have been digitised and can be found on (£/$)

For an overview of Black experiences in Britain during the Second World War we recommend:

  • Black and British: A Forgotten History, David Olusoga (2016)
  • Rich Relations: The American Occupation of Britain 1942-1945, David Reynolds (2000)

Escape, evasion and helpers

Escape and Evasion Reports are available to download from NARA

The Comète Network, provides an online database of Allied airmen assisted by French and Belgian Helpers during the Second World War. The primary language is French, but is easily navigated with the support of online translation tools.

The Air Forces Escape and Evasion Society also have a long list of resources for researching evaders and their helpers.

Prisoners of War

NARA’s Access to Archival Database lists basic details of Americans who were taken prisoner of war (POW) during the Second World War, Korean War and in Vietnam. Their captured document collections, also contain Downed Allied Aircraft Kampfflugzeug Unterlagen (KU) Reports relating to combat aircraft shot down in occupied Europe, and usually mention air crew captured.

Records of POWs were compiled by each country and are now held centrally by the Archives Division and Research Service of the International Committee of the Red Cross in Switzerland. Because of their personal nature, these records are not available to the general public. Prisoner of War Records for the First World War have been digitised

Sources at IWM include personal papers and diaries, autobiographies, camp journals, photographs, artworks and recorded interviews, although inevitably some locations and periods are better documented than others. These can be extremely helpful for contextualising life as a prisoner of war.

Victims of atrocities

The Jewish Virtual Library hold digital transcripts of many of the major trials brought against Nazi Germany following the Second World War. Many of the charges concerning atrocities committed against Allied prisoners of war were trialled at Dachau from 1945 to 1947.

MACRs and KU Reports, both available from NARA may also provide details on atrocities committed against downed allied fliers.

The Library of Congress’ Veterans History Project preserves memories and oral histories of veterans who served in conflicts from the First World War to date. 

Many Bomb Group and Fighter Group associations have their own websites, which contain newsletters, memories and personal stories.

Tracing American relatives

GI Trace provides resources and information to assist people trying to find their American fathers or families.  



Getting started

The serial number is often the most important piece of information you need to research any American aircraft.  

In full, US aircraft serial numbers take the format XX-XXXXX. The first two digits indicate the year the aircraft was ordered, though often the first digit is not displayed on the aircraft’s tail.

Joe Baugher lists aircraft serial numbers used by the US Air Force and its predecessors from 1908 to date, along with detailed information about changes in numbering conventions. Specific aircraft can be found via the search engine.

Single military aircraft histories are detailed in Individual Aircraft Record Cards (sometimes called Aircraft History Cards). Copies for aircraft from 1920- 1953 are held at the National Air and Space Museum (NASM) and the Air Force Historical Research Agency (AFHRA), and cover the life of an aircraft from its acceptance by the armed forces to its removal from the inventory.

An aircraft serial number can also be helpful in tracing people’s stories, especially if they were part of an aircrew.

Aircraft types

Biographies of every B-17 Flying Fortress built are available on our website.

For other aircraft types we recommend:

Technical manuals can be viewed freely at AviationShoppe

Crashes and accidents

Missing Air Crew Reports (MACRs) list details of aircraft lost on combat missions, MACRs can be accessed via NARA’s Microfilm Catalog or at Fold3(£/$). They often include the type, model, and serial number of the aircraft and its engines, the unit to which it was assigned, the place of departure and destination of the flight plan, and cause of crash.

Aircraft accident reports and be searched or ordered from Aviation Archaeology ($)

Aircraft crashes were recorded in daily listings of mishaps, or in weekly or monthly intelligence summaries compiled at Squadron or Group level. Information about losses was sometimes recorded on Individual Aircraft Record Cards too. All of these sources should be obtainable on microfilm from AFHRA or NASM.

In the UK, aircraft crashes and accidents were also recorded by Air Raid Precautions (ARP). Many records are held in county record offices, The National Archives (TNA) search can help you to locate one local to you. Local newspapers may also contain information about aircraft crashes too.

Well documented aircraft crash sites are often commemorated with memorials, you can find details of many of these on our website or at IWM’s War Memorial’s Register.

In the UK, the remains of all aircraft which crashed while in military service, whether on land or at sea, are protected by the Protection of Military Remains Act 1986, interference is considered a criminal offence.

Many European countries have similar legislation in place to protect military aircraft crash sites. If you believe you have located a crash site, report it to the local authorities or the Defense POW/MIA Accounting Agency (DPAA)

Colours and markings

Our ever-growing media section features thousands of images of aircraft from a range of USAAF units, and is a rich resource for determining an aircraft’s appearance.

The US Army Center for Military History outlines colour guides for combat aircraft from 1940 to date. US Air Force colour guides from 1919 to date are listed at

The Battle Colours series by Robert Watkins are a useful reference for US aircraft liveries during the Second World War
