Short answers, pulled from the story.
Estêvão Gomes, also known as Esteban Gómez, was a Portuguese explorer born around 1483 and killed in 1538. He was born in Porto and sailed in Castile's service, first with Ferdinand Magellan's fleet and later on his own expedition along the North American coast.
Estêvão Gomes wanted command of a ship, but Magellan passed him over for a captaincy in favor of his inexperienced nephew, Alvaro de Mesquita. Near the Strait of Magellan, Gomes overpowered Mesquita, took control of the San Antonio, and sailed back to Spain in May 1521.
In 1524, Estêvão Gomes explored the coast of present-day New England and Nova Scotia aboard the caravel La Annunciada. He sailed up the Penobscot River to the future site of Bangor, Maine, and named landmarks including the Merrimack River and Cape Cod.
Cartographer Diogo Ribeiro used information from Gomes's voyage to draw his 1525 Castiglione map, the first to show a continuous North American coastline from Florida to Nova Scotia. Ribeiro labeled the New England region Tierra de Esteban Gómez, the Land of Estêvão Gomes.
Estêvão Gomes abducted at least 58 native people near the Penobscot and brought them to Spain as evidence of a potential slave trade. After a mix-up over whether his message reported slaves or cloves was cleared up, King Charles ordered the captives freed.
Estêvão Gomes was killed by natives of the Paraguay River in 1538, while serving on Pedro de Mendoza's expedition to the Río de la Plata, which he had joined in 1535.
