Mr John Neil Coyle was born in Liverpool, England on 25 August 1880. One of six children, he was the son of Bernard Coyle, a mariner (chief steward) originally from Belfast, and Jean Bell of Fife, Scotland.
Coyle appears on crew manifests as early as 1900 and he served as a waiter board, among other ships, Lucania, Majestic and Campania; by December 1911 he was the barkeeper aboard the Saxonia, his ship prior to that having been the Royal George.
A Freemason, he was married in 1903 to Margaret McLeod Lochead (b. 1879 in Liverpool to an Irish father and a Scottish mother) and they had a daughter, Jean Bell (b. 1905). By 1911 the family lived at 28 Dursley Road in Bristol.
John Coyle was barkeeper aboard the Carpathia when that ship rescued the survivors of the Titanic.
Coyle later left the sea and emigrated with his wife and daughter to Canada, settling in Montréal where he worked as a chef. He died on 19 March 1958 and was buried in Mont-Royal Cemetery in Montréal.
