Gilbert and Ellice Islands French captain Louis Duperrey was the first to map the whole Gilbert Islands archipelago. He commanded "La Coquille" on its circumnavigation of the earth (1822–1825). Funafuti atoll was named Ellice's Island after Edward Ellice, a British politician and merchant, by Captain Arent de Peyster, who sighted the islands in 1819 sailing on the ship "Rebecca". Ellice owned the cargo of the ship. The name Ellice was applied to all nine islands, of what is now Tuvalu, after the work of English hydrographer Alexander George Findlay. The Gilbert and Ellice Islands were formerly designated an ISO 3166-1 alpha-2 country code "GE"
