German Military Grave Registration Service

The German Military Grave Registration Service database contains more than 2 million names of missing and dead German soldiers from World War I and World War II. All that is necessary is a surname (nachname) to search. On the first visit you will be required to register with your name and address (Straße/Nr. - Street and Number, Land - Country, PLZ - Postal or Zip Code, and Ort - City) to view the search results.  Be aware the site is in German, which can make navigating the site challenging - my one year of high school German was not really adequate to the challenge!

Internment.net

Interment.net is a free online library of cemetery records for historical and genealogy research.  The database contains over 3 million records from over 5000 cemeteries worldwide and contains actual cemetery transcriptions as well as links to other cemeteries around the world. You can search cemetery burial records or browse records by region.  While coverage is not extensive in some areas it is well worth browsing their list of cemeteries to see what is available.

Free access to Irish Records with Find My Past

On June 30, 1922, the Public Records Office of Ireland, located at the historic Four Courts in Dublin, caught fire during the Irish Civil War. Tragically a considerable amount of Irish records were destroyed.

Australian War Memorial

ANZAC Connections: Centenary digitisation project

The Australian War Memorial is currently undertaking a project to create a comprehensive digital archive of the ANZACs and their deeds, and of the wider Australian experience of war. The collections selected for this project will reflect the experiences of Australian servicemen, nurses and civilians during the First World War, not just well-known personalities. This project will digitally preserve the Memorial’s collections as well as provide full copies for research on the Memorial’s website.

Lives of the First World War

Digital publisher Brightsolid and the Imperial War Museum are creating a new platform to capture stories from the First World War.  Called Lives of the First World War, the website will enable people to share the stories of men and women who served in Britain and across the Commonwealth.  After registering on the sire for free, researchers will be able to add details about their ancestors, uploading photographs and other documents.  The site will also offer access to digitised records from libraries and museums such as The National Archives and Commonwealth War Graves Commission.  The launch of the new website is part of the Imperial War Museum's program of events to commemorate 100 years since the outbreak of WW1 in August 2014.
