There are many resources available for you to learn more about your Second World War ancestors. Here's a comprehensive guide to help

The Second World War (1939-1945) was one of history's most catastrophic conflicts. The first truly global war, it claimed over nine million lives and affected the vast majority of families across the UK and Europe.


Many of you may have known someone who served during the war, and some of you may have been lucky enough to hear firsthand accounts of their experiences. Researching Second World War records can be very rewarding as you will often be searching for someone you knew personally or had direct contact with at some point in time. We've put together a list of go-to resources for learning more about the lives and military careers of those involved.

Army Roll Of Honour 1939-1945

A military roll of honour is simply a list recording the names of those who have died in battle.

Sourced from an original documents held at The National Archives, our 1939 - 1945 Roll contains the details of more than 171,000 servicemen and covers all credits (infantry, the artillery and all supporting corps) and all ranks (officers, non-commissioned officers (NCOs) and other ranks).

If your ancestor was killed in action died or was recorded as missing presumed dead while serving in the British Army between 1st September 1939 to 31st December 1946 they're name will appear in this roll. From these records you may be able to learn their service number, place of enlistment, rank, regiment and date of death, as well as their nationality, place of birth, marital status, civilian occupation and residence.

British Army Casualty Lists 1939-1945

The British Army casualty lists 1939-1945 include over a million entries from volumes which were updated by the War Office on a regular basis from 1939 to 1947. The lists document the names of officers, nurses, and other ranks who were reported as killed in action, dead as a result of illness or accident, missing, or taken as a prisoner of war. Later records show the names of those who were previously listed as a prisoner of war or missing but had died or those who were listed as a prisoner of war and were now free.

Individuals can appear in the lists more than once if their status was reported to have changed. For example, E C Young was first reported missing, then reported missing and presumed a prisoner of war, and finally reported as a prisoner of war. Each entry recorded the person's name, rank, service number, regiment, status, and previous theatre of war.
