Was one of your relatives held prisoner during WWI? The Red Cross just launched a new tool that could help you find out what happened to them.
Data on 2 million prisoners, primarily from the Western, Romanian and Serbian Fronts have been collected during the war by the International Prisoners of War Agency, set up by the ICRC in August 1914.

Couldn't find nothing from the 4 families of my grandparents.
Should ask about the family names of a previous generation
