Money paid by the Government to families of men killed in the First World War and Boer War are listed in newly-digitised records.
Family history website Ancestry said the information covers more than 870,000 soldiers and shows that mothers were the most commonly listed next of kin.
The average payment was £10.35 – equivalent to £929 today – made up of any final pay balance plus a gratuity from the War Office, said the report.
The sheer number of deaths meant the money offered seems “relatively minor”, said Ancestry.
Military figures in the collection include Second Lieutenant Walter Daniel John Tull, a professional footballer who played for Tottenham and Northampton and was the first black man to be commissioned as an infantry officer in the British Army, Private John Condon, believed to be the youngest known battle casualty of the First World War, and Lieutenant Raymond Asquith, elder son of prime minister Herbert Asquith.
Miriam Silverman, senior UK content manager at Ancestry, said: “This collection serves as a stark reminder of the millions of soldiers killed in WW1 and the Boer War.”
