Findmypast.co.uk adds 1861 Worldwide Army Index

Findmypast.co.uk's 1861 Worldwide Army Index (or The 1861 Worldwide Soldier Index) was complied from the extraction of details of some 245,000 serving soldiers listed in the National Archives April-June quarter Paylists held in WO 10 (Royal Artillery), WO 11 (Royal Engineers) and WO 12 (Cavalry, Guards, Infantry and other units) series War Office records.
It includes records not only of other ranks of soldiers serving in Britain, but also men serving in Queen Victoria's Army far-flung empire outposts. For this reason, it can be an exceptionally useful source in identifying men missing from the 1861 census returns.
The index provides the names, ranks, army numbers and regiments of about 98% of other ranks subjects serving in the British Army. A small number, estimated at about 5000 men, is not included because the Paylists listing their names have not survived.
