George held the role of Acting Bombardier in the Royal Field Artillery, D Battery of the 94th Brigade. 

In the 1901 census George's family is living on Church Street, Conisbrough. He is at this time the only child of George Brumby and Clara Annie Appleyard. In the 1911 census, he is listed the eldest of three children, having a younger sister and brother. 

In 1911, George held the position of 'Business Assistant' and the family were still living at 33 Church Street in the building which is now occupied by the newsagents, (formerly Joey's) at the Nat West end of the road. 

Examination of the earlier 1891 census shows George's father (also George) living  next door at 35 Church Street, in the building now occupied by the 'Remove It All' store. George Snr is listed as a Grocer's Assistant and his own father (George's grandfather, also George) is listed as 'Grocer, Draper, Cabinet Maker'. It appears the family were not struggling to survive, as the census lists a servant, John Gibson.  

George was a single man at the time of his death, and was killed on Tuesday, June 13th 1916. He had been in charge of a gun battery, and was killed when a shell exploded at the nozzle of one of his own guns. George also held a 1st class certificate in signalling, and acted as a signaller at the Battle of Loos.

George's great grandfather was buried in Conisbrough graveyard with military colours, following the Battle of Trafalgar.
