This site says, under porter: "Porter’s name comes from the Porters at London’s Victoria Station." Wrong! Porter as a drink is 130 or so years older than Victoria Station, and the name comes from London's street and river porters of the reign of George I
It also says: "Arthur Guinness and Sons was the first brewer to offer a Porter commercially." Wrong! Porter was developed by brewers in London 40 years or so before Arthur Guinness began brewing. Guinness never brewed porter at first, and started brewing the drink only in the 1770s or thereabouts, in response to increasing amounts of porter being imported into Ireland from England.
What this site needs is to read a good book on brewing history ...
