The last French winner of the maillot à pois, awarded to the best climber in the Tour de France, was Pierre Rolland. He secured the polka dot jersey in the 2011 Tour de France. Since then, no French rider has won this distinctive jersey.
The Bailiwick of Jersey, the British Crown dependency, 12 miles off the north coast of Normandy France which gave the American State of New Jersey it's name, is in a branch of the Atlantic Ocean known as the English Channel (or La Manche in French). This gives Jersey and it's neighbor Guernsey the name 'the Channel Islands'.
Jersey is not a country, but a crown dependency of Britain. French is an official language of Jersey, much of the law was recorded in French. Jerriais is the regional dialect, which is quite similar to French, however not many people can actually speak it anymore. English is the main language, our TV is english, radio, we talk to each other in English, schools teach in English.

Yes there is one in Little Silver New Jersey. They have many gourmet foods including French, and Italian.
Your question does not make sense. A "francophone" is a person who likes speaking French. Some people in Jersey speak French, many many more speak English. In some rural districts they still speak a 'Jersey patois', a mix of old French and old English.
