Mr William Keenan was born at 20 Little Ship Street in Belfast, Ireland on 15 June 1875. Hailing from a Unitarian family, he was the son of Thomas Keenan, a stonemason, and Martha Hewitt. He had one elder brother and two sisters.
Both the 1901 and 1911 censuses show the Keenan family living at 35 Cooke Street in south Belfast and William was described as an unmarried sailor on the latter.
Keenan’s ship prior to Titanic had been the Olympic. He joined Titanic at Belfast for the delivery trip to Southampton where he then disembarked.
William enlisted for the War effort in October 1914 and was described as standing at 5’ 7½” and with brown hair and eyes and he had a tattoo of a woman on his left arm. He was discharged within a fortnight as it was deemed he was not likely to become an efficient soldier.
