Harold Edward Musson was born in military barracks in England. He spent his youth in the environs of Alton, a small town in the Hampshire Downs, and was equally influenced by the nearby town of Aldershot. His father, Edward Lionel Musson, was Captain in the 1st Manchester Regiment and it is very likely that young Harold spend some time in India or Southeast Asia while Lionel Musson was on his assignments.
