The UK's largest family history website, Ancestry.co.uk, this week completed its publication of pension records for the British Army in World War I.
Pension records might not necessarily sound glamorous or exciting, but the database - officially known as the WO364 records - offers a fascinating insight into lives of soldiers in the great war, and a timeless record of their lives.
Details such as soldier's length of service and nature of wounds sustained are included. And each file should contain the serviceman's date and place of enlistment, tours of duty undertaken and peacetime occupation.
(Families searching for their relatives should be aware that medical history is included in detail, too, and sexually transmitted infection was a fact of army life at the time...)
The pension files themselves have led an interesting life: they are also sometimes referred to as the "unburnt records", because unlike many Great War records, they survived the London Blitz in the 1940s.
