Death of British Merchant Navy seaman

Hi This is my first Post, I do Genealogy for the Seamanshome forum in England.
I have struck a brick wall while tracing an English AB seaman (Fireman).
William Dwyer born 1877 Liverpool England, spent most of his life as an Fireman from around 1902 till his death around 1920~1927.
I have traced William Dwyer through the Crew lists between 1902 through to 1912, he seems to have done many trips on the ship Haverford . One trip on the Empress of Britain in 1912.
It was reported that William Dwyer fell some 20 feet in the boiler room had very bad head and neck injuries and died some hours after. He was taken to Boston Mass and buried .
No info has been found regarding the ship he was on or date , nor at this time have we found any info regarding his burial in Boston around 1921~1927.
Any help would be wonderful.
