William Clark, 39, was born in 1876 in Greenore, County Louth, Ireland.
A newspaper report in 1914 suggested he had served during the Boer War.
In 1911 he was listed living at 30 Paget St, Southampton with his (?common-law) wife, Mary Jane Humphrey1.
When he signed-on to the Titanic, on 6 April 1912 he gave his address as 30 Paget Street, (Southampton). His last ship had been the Avon. As a fireman he received monthly wages of £6.
Clark was rescued in Lifeboat 15.
He seems to have moved to Liverpool.
He would also survive the sinking of the Empress of Ireland in 1914.
''Fireman E. Clarke, of Liverpool, one of the survivors from the Empress of Ireland, was also in the Titanic when she went down. ''I have done with the sea, ''he told an interviewer; this last affair has settled it. It's me for the shore. I'm not going to risk a third time. I was in No. 15 boat when the Titanic was lost, and I helped to save lives. Just starting my watch I was, and we had lots of time to lower the boats.....'' (Luton Times and Advertiser, June 12, 1914)
