Analysis of information sources in references of the Wikipedia article "Duke of Clarence" in English language version.
Clarence is tainted by more than a bit of bad luck, for instance, with one Duke of Clarence executed by his brother as a traitor (Shakespeare even wrote about that particular incident). Another Duke of Clarence, the grandson of Queen Victoria, got himself mixed up in a scandal involving a gay-prostitution ring. He later died of influenza at just 28.
Clarence has had a chequered history as previous holders have died young, been drowned in a barrel of Malmsey wine or erroneously rumoured to be Jack the Ripper.
