Kidnapped by traders along the coastline of North America, Squanto found himself on the auction block in Spain only to be rescued from slavery by Spanish friars. He eventually made his way to London where he learned English while working for shipbuilder John Slany. English investors, including Slany, agreed upon Squanto's return to North America, perhaps with the specific purpose of establishing communication with Native American Beothuk and expanding the Cuper's Cove fur trade.
After spending about a year in Cuper's Cove, Squanto joined another English trader who hoped to further explore the New England coastline. He arrived in New England in 1619. The Pilgrims appeared that next year and soon discovered his usefulness as a translator.
Small world in the world of history, eh?
