Frank Haynes was born in Longton, in Staffordshire, in 1891. His father, John Haynes, died at the age of 34 in 1894, and it is possible that his mother, Mary Ann Haynes, died too (there are a few possibilities). By 1901 he was living with his grandparents, George Henry and Elizabeth Taylor, at 100 North Street, together with his brother, George Henry Haynes. Frank may have married in December 1911, as this would make him 20 years old.
In September 1914 he joined the Royal Navy and became an Able Seaman (KP/558). He died in action in the Dardanelles on 4 June 1915, and this was noted in an article in the Express & Star on 23 June 1915. He is commemorated at the Helles Memorial in Turkey.
