Palmerston, Cook Islands
All of the Palmerston islanders are descendants of one Englishman, William Marsters, who arrived there in 1863 and went on to have four wives and 17 children.
Supply ships visit the island only a few times a year, there are two telephones, and internet access is only available for four hours a day.
Palmerston is a two-day sailing voyage away from Rarotonga, the capital of the Cook Islands, and an eight-day trip from Tahiti.
