He had an older brother and at least 2 sisters.
His father Archie, a Shoemaker, died when John was 6 years old.
John worked as a Flax Mill Labourer until, in March 1907, when he enlisted in the navy. In March 1912, he transferred to the Royal Fleet Reserve, Chatham.
At the outbreak of war, John’s widowed mother (a seamstress) was living with one of his sisters at Spring Street, Belfast.

On 22 September 1914 his ship was torpedoed by German submarine U9.
