Daniel Barrett was born 1897 in Ballyvorane South, Nohoval, near Kinsale, County Cork, Ireland, the son of Cornelius and Norah Barrett. In 1915 he lived at 2 Middle Street, Liverpool, Lancashire, England.
He was employed by the Cunard Steam Ship Co as a fireman in the Lusitania's Engineering Department when the liner departed from Liverpool for New York on the 17 April 1915, and he was serving in the same capacity on the return voyage.
On 7 May, as the great liner passed by the Old Head of Kinsale, and almost within sight of Daniel Barrett’s home, a torpedo launched by the German submarine,
U-20, struck the Lusitania on her starboard side which resulted in her sinking within 18 minutes. Daniel Barrett lost his life as a result, and if his remains were ever recovered, they were never identified. He was aged 18 years.
As his body was not recovered and identified afterwards, he is commemorated on the Mercantile Marine Memorial at Tower Hill, London.
