Do a Google search for the Angel of Mons as well. Fascinating the way the media and individuals (on both sides) were so keen to get God on their side. The figure with the olive branch is winged Victory. Good luck finding out about your family. I have an in law who came over from Oz and looked up his family history. Found 7 great uncles who joined up or were in already and 5 were killed in the war. Can't leave the subject alone now and know more about the Somme than Douglas Haig!
These were the standard two awarded (I have my Great Uncles' - one from KRRC KIA 1918 and one from RA - he survived but his only son was killed in N Africa in WW2 so no direct descendants - I have the son's medals too including an Africa Star)
If the soldier had served in 1914 or 1915 prior to the start of conscription they would also have been awarded the 1914 star or the 1914/15 star as appropriate. See the National Archives link in polar's post for details.
less than 40% of soldiers' service records from WW1 do survive at the PRO and they are fascinating if you get lucky. You need to either go to the PRO yourself or engage a researcher to find them for you (details on the website). I have one set for a relative who died in Salonika in 1918 as a Sgt Royal Fd Artillery and they are a fascinating record. Ironically the 60+% of records that do not survive were destroyed by the Luftwaffe in the 1940s.....
