John McLoughlin was born in Liverpool, Lancashire, England, in 1883, the son of Patrick and Isabella Amelia McLoughlin. He grew up at 52. Robsart Street, Everton, Liverpool. He was married to Margaret Ann McLoughlin (née Bigley) in Liverpool on the 20th March 1904, and in 1915, the family home was at 76, Victoria Square, Liverpool, Lancashire.
He engaged as a greaser in the Engineering Department on board the Lusitania, at Liverpool, on the 12th April 1915, at a monthly rate of pay of £7-0s-0d.
He was killed as a result of this action. He was aged 32 years.
His body was not recovered and identified afterwards and as a result he is commemorated on the Memorial to the Missing of the Mercantile Marine at Tower Hill, London.
In August 1915, he was officially discharged from the last voyage of the Lusitania
and his widow, Margaret, was paid the balance of wages owed to him, in respect of his service on board the
Lusitania from 17th April 1915, until 8th May, 24 hours after the vessel had gone down! In addition, The Liverpool and London War Risks Insurance Association Limited granted her a yearly pension to compensate her for the loss of her husband which amounted to £46-16s-4d. (£46.81½p.) which was payable at the rate of £3-18s-1d. (£3.90½p.) per month.
