Romney Marsh is famed for its sheep. In fact, if you eat New Zealand lamb, there's a good chance that that cutlet was descended from a Romney sheep - the local breed proved to be so hardy and so good at wool bearing that it got exported all over the world.

Mitt Romney's family was a less successful export.
