Thomas Costello was born in Westport, County Mayo, Ireland in 1885. He lived at 55 Kendrick Street, Liverpool, Lancashire.
He engaged as a fireman in the Engineering Department on board the Lusitania at Liverpool on 12 April 1915 and reported for duty at 8am on 17 April for the liner’s last ever voyage out of the River Mersey. As a fireman his monthly rate of pay was £6-10s-0d (£6.50).
He was killed when the Lusitania sunk just three weeks later. He was 30 years old.
His body was not found and identified afterwards, so his name is recorded on the Mercantile Marine Memorial at Tower Hill, London.
