The data comes from the Commonwealth War Graves Commission, who kindly allowed us to share the astonishingly rich data that they have painstakingly put together over the years.
You can search by any combination of first name (or initial), surname, street or town/city.
You don't have to fill in all the boxes - you can fill as many or as few as you like.
The database allows you, for example, to search for people with the same name as you, who came from the same city - or just to see who died from the street where you live.
Do you know of relatives, friends families or neighbours who fought in the Great War? Send your photos and stories to graham.spence@trinitymirror.com
