Sandwich (the town) indrectly gave its name to the popular picnic item - the 4th Earl of Sandwich reputedly invented it by asking for a bit of meat between two slices of bread so that he could eat at the gambling table rather than taking breaks for meals!
The same Earl of Sandwich also had some Pacific Islands named after him - the Sandwich Islands, now better known as Hawaii. The 'Sandwich' name lives in on the scientific name of the Hawaiian Goose/Ne-Ne - Branta sandvicensis.
The Sandwich Tern, Thalasseus sandvicensis, however, is named after the town.
All that's not really relevant, but quite interesting!
