Schooling was at Campbell College between February 1900 and April 1902. The 1901 Irish Census records him as a resident of house 2.4, Ballycloughan, Ballyhackamore, Belfast. [This was to become the Knock Road, Belfast].
However, the Campbell College book ‘The Campbellian’ (Volume IV, Page 73) records Christie as working for the Belfast Bank and later for the Canadian Bank of Commerce.
By 1911, Christie was boarding in house 6, Newington Terrace, Rathmines & Rathgar East, Dublin. He is described as a Bank Official.
Christie was working in College Green, Dublin when he enlisted as a Private with Service Number 106604.
