My mother (nee Mitchell) says that this is her Grandfather and remembers him telling the story of the Titanic to her when she was a girl.. However I can't find anything to link him to Hull. He would have been 47 years old when my mother was born.
George Beachamp was never in hull. He did not die in 1944 as your great grandfather did. His true details are as above. He died in 1965 at the woolpack inn, Redbridge, Southampton. This was my family home and I was there when he died. He was never on the Lusitania. I am sorry to tell this but this was a mistaken identity.
