John Thomas Orange was born in Balbriggan, County Dublin, Ireland in 1890, the son of Joseph and Mary Orange of 12 Chapel Street, Balbriggan, County Dublin. He was one of eight children.
He engaged as a fireman in the Engineering Department on board the Lusitania at Liverpool on 12 April 1915, at a monthly rate of pay of £6-10s-0d (£6.50) and was killed when the liner was sunk. He was aged 25 years.
His body was not found and identified afterwards, so his name is embossed on the Mercantile Marine War Memorial at Tower Hill, London.
