William Jones was born in Liverpool, Lancashire, England, in 1866, the son of Mr. and Mrs. John Jones. He married Margaret Duggan in Liverpool on the 28th June 1888, and in 1915 they lived at 9, Severs Street, Anfield, Liverpool.
He engaged as an able seaman in the Deck Department on board the Lusitania at Liverpool on 12th April 1915 and reported for duty on the morning of 17th April, before the vessel left the River Mersey for the last time. As an able seaman, his monthly rate of pay was £5-10s-0d., (£5.50p).
He was killed three weeks later, when the vessel was torpedoed and sunk, one week out of New York. His body was not recovered and identified afterwards.
As a result of having no known grave, he is commemorated on the Mercantile Marine Memorial at Tower Hill, London. He was aged 49 years, although when he engaged, he gave his age as 51 years.
