Thomas Connaughton was born in Liverpool, Lancashire, England on 6 January 1892, the son of Joseph and Ellen Connaughton of 38 Lennox Street, Liverpool, Lancashire.
He served as Extra Third Cook in the Stewards' Department on board the Lusitania and was killed when she was sunk.
His body was not amongst those recovered from the sea and identified and as a result his name is embossed on the Mercantile Marine Memorial at Tower Hill, London.
Cunard records show one of the missing to have been Extra Third Cook Thomas Connertin and this is certainly the same man, the disparity of spelling probably occurring when his name was written down as he engaged for service. Also, according to the 1901 and 1911 English Census, the family surname is spelt as Connorton, which is also incorrect.
