Peter Donoghue was born in Ormskirk, Lancashire, in 1865, the son of Peter and Ann Donoghue. In 1915, he lived at 26 Elm Road, Walton, Liverpool with a number of his unmarried siblings, their parents being deceased.
He was a professional seaman in the British Mercantile Marine, and he was employed as a greaser in the Engineering Department on board the
Lusitania and was killed when the ship was sunk.
His body was never recovered and identified afterwards and as a consequence, he is commemorated on the Mercantile Marine Memorial at Tower Hill, London. He was aged 50 years.
When his will was proven on 23rd December 1915, administration was granted to his older brother, John Donoghue, whose occupation was also given as 'greaser'. Peter Donoghue's effects amounted to £200.
