Well here's my question: how do you pronounce Poughkeepsie? Des Moines? Saint Louis?

As for British suburbs, they were often named, like American ones, after other British places... so there's a Wapping in Liverpool, a Soho in Birmingham, and a Hackney in Matlock, all of which names were originally associated with London. There's also a New Zealand in Derbyshire, which according to urban legend became famous some years ago when an escaped wallaby was run over by a car there. The driver called the police, who asked him for details. Convincing the Derbyshire police that he'd run over a wallaby in New Zealand wasn't easy.
