Leif Erikson
Leif Erikson or Leif Ericson ( 970 – c. 1020) was a Norse explorer from Iceland. He was the first known European to have set foot on continental North America (excluding Greenland), before Christopher Columbus. According to the Sagas of Icelanders, he established a Norse settlement at Vinland, tentatively identified with the Norse L'Anse aux Meadows on the northern tip of Newfoundland in modern-day Canada. Later archaeological evidence suggests that Vinland may have been the areas around the Gulf of St. Lawrence and that the L'Anse aux Meadows site was a ship repair station.
Richard Amerike
Richard ap Meryk, anglicised to Richard Amerike (or Ameryk) ( 1440–1503) was an Anglo-Welsh merchant, royal customs officer and, at the end of his life, sheriff of Bristol. Several claims have been made for Amerike by popular writers of the late twentieth century. One was that he was the major funder of the voyage of exploration launched from Bristol by the Venetian John Cabot in 1497, and that Amerike was the owner of Cabot's ship, the "Matthew". The other claim revived a theory first proposed in 1908 by a Bristolian scholar and amateur historian, Alfred Hudd. Hudd's theory, greatly elaborated by later writers, suggested that the continental name America was derived from Amerike's surname in gratitude for his sponsorship of Cabot's successful discovery expedition to the 'New World'. However, neither claim is backed up by hard evidence, and the consensus view is that America is named after Amerigo Vespucci, the Italian explorer.
