It seems he went from Greenhill School to study Agriculture at Aberystwyth University (thanks to Steve John for the info).
H.S.Glanville is also recorded on the War Memorial at the University, as well as at Greenhill.
We were also contacted by a Mr Powell whose grandfather fought alongside H.S.Glanville at Gaza.
It seems Benjamin Morgan rescued H.S.Glanville from the field of battle when he had been injured. This was such a daring deed of bravery under fire that Benjamin was awarded the Military Medal. Unfortunately H.S.Glanville died from his wounds.
Benjamin Morgan survived the war unscathed, only to later die from a fall in 1927.
Hugh Slader Glanville must have left a lasting impression on his friend Benjamin who later went on to name his son 'Glanville' in honour of his lost comrade.
It seems the Military Medal left the family after Benjamin Morgan died in an accident aged just 30 years - leaving his wife with two young children to bring up alone.
