The name "Guernsey", as well as that of neighbouring "Jersey", is of Old Norse origin. The second element of each word, "-ey", is the Old Norse for "island", while the original root, "guern(s)", is of uncertain origin and meaning, possibly deriving from either a personal name such as Grani or Warinn, or from gron, meaning pine tree. Like Jersey, the territory was a former part of Duchy of Normandy, and remained under English control after Philip II of France took the rest of the Duchy over and Normandy became part of France, eventually being recognized as part of Henry III's territories in the 1259 Treaty of Paris. The island was also taken over by Germany in the 30th of June, 1940 until the 9th of May, 1945, and was very heavily fortified by the Germans, with remnants of the defenses still existing to this day.
Guernsey is known for its cows, which are prized worldwide for their rich creamy milk which is claimed to hold health benefits over milk from other breeds, as well as their distinctively flavoured and rich yellowy-fatted beef and distinctive yellow butter. Guernsey is also a popular offshore finance center for private equity funds because of its light tax and death duties.
