John Ennis was born in Liverpool on the 21 March 1878, the son of William and Catherine Ennis. His father, who was born in Ireland, was at various times a hairdresser and dock labourer
On 15th January 1905 he married Mary Guthrie in Liverpool and in 1915 they lived at 12 Court, 7 House, Burlington Street, Everton, Liverpool with their children.
John Ennis was a professional marine fireman and greaser in the British Mercantile Marine and was employed as a greaser in the Engineering Department on the final voyage of the
Lusitania. He was killed when she was sunk. He was aged 37 years, although when he signed on for the voyage, he stated his age as being 34 years.
His body was never recovered and identified, so he is commemorated on the Mercantile Marine Memorial at Tower Hill, London.
In August 1915 he was officially discharged from the last voyage of the Lusitania
and his widow Mary was paid the balance of wages owing to him for the voyage, calculated from 17 April until 8 May 1915, 24 hours after the liner had foundered.
The Liverpool and London War Risks Insurance Association Limited granted a yearly pension to Mary Ennis to compensate her for the loss of her husband. This amounted to £36-2s-3d (£36.11) payable at the rate of £3-0s-3d.(£3.01) per month.
