WWI Medal Index Cards contain details of soldiers' medal awards, full name, rank, regimental number and theatre of war first served.
WWI Medal Rolls give further detail of particular Battalions served and date of enlistment (from here it is possible to chart your relative's troop movements (we can advise on how to do this).
Full Service Record searches are not always successful, as many WWI records were destroyed during the WWII Blitz. These records often have places of birth filled in by the soldier, appearance details, including birth marks, scars, tattoos and all (!), signatures of soldier and Commanding Officer, lists of troop postings, movements and any wounds suffered.
In order for us to try and research your relative, we require as many details of his military career that you can give, where possible regiment, regimental number, full name and date of birth.
