Mr Richard William May was born in St Mary at Hill, Billingsgate in the City of London on 5 March 1858, the son of Richard William May (1832-1887) and Susan Ellen Mann (1833-1913). His father had risen from being a porter to becoming a successful fishmonger at Billingsgate fish market.1
He had six siblings: Philip Charles May (1859–1900), Walter Moss May (1861–1893), Stanley James May (1866–1946), Susan Amy May (1868–1950), Lily May (1871–1966) and Fred May (1872–1936).
In 1912 Richard May was joining other members of his family for a motoring holiday in Ireland. They were his brother Stanley, and sister Lily, her son Jack and her husband Herbert Odell's sister Kate. Herbert Odell himself bought the ticket for six people but in the end did not join the trip.
Richard seems to have had a keen interest in transport, and the Olympic class ships, he may possibly have had a business interest in the White Star Line itself. Therefore it is likely that they deliberately chose the Titanic for the trip to Ireland.2

Richard May and the rest of the party disembarked the Titanic at Queenstown to continue their holiday.
After the Titanic disaster, Richard May corresponded with fellow cross-channel passenger Father Francis Browne regarding his photographs of the Titanic.
Richard May continued the fish-market business; he never married. He died in Twickenham, London on 21 March 1938.
Richard William May is buried with his mother and Father in Kensal Green Cemetery, Royal Borough of Kensington and Chelsea, London, England (Section 73, Row Pathside, Plot 19122); Richard is not mentioned on the headstone.

I am interested in finding out any information on the May family that disembarked in Queenstown with Father Browne.
