The London & North Western Railway steamer Connemara collided with the collier Retriever during a severe gale on the night of 3 November 1916. It transpired that the collier was without lights, as her lamps had been extinguished by the mountainous waves. Details of the Connemara can be found in Railway & Other Steamers by Duckworth & Langmuir (1948), while the accident will presumably have been reported in The Times (available on-line). Both ships sank almost immediately; 51 passengers and 31 L&NWR employees died aboard the Connemara, although a number of cattle were able to swim ashore despite the furious storm.
Simon -- some years ago your post was requesting anything to do with a casualty list. Only a small number of dependants appear with the 1924 Relief Fund report I actually obtain, which outlines the finicial year ahead, and giving instructions on the Area Committee's own burgets to keep within each quarter - which I am afraid was never a good gudeline as most always overestimated the burget quota leaving the London Mansion House Committee going barking mad with anger. If you wish I could send you copies but there's no reference to the main namesake you were searching for some years back. He's an intriguing marvel, one hell of a big mystery. I wonder if he ever did exist??
