Miguel de Entrambasaguas was born sometime before 1517 in Burgos (Burgos) to Diego de Entrambasaguas and María de Castro. He obtained his license to travel to New Spain in May 1537. He was more than twenty-three years old when he went on the Coronado Expedition as an unassigned horseman. When the Expedition returned Miguel stayed in Mexico City for at least a year. Then he joined the Gasca force that was sent to Peru to help put down the Pizarro revolt. Entrambasaguas married doña Isabel Pizarro, the daughter of Pedro Piçarro, a cousin of Francisco Pizarro, and had two sons and three daughters. By the 1570s he was living in Quito, Ecuador until at least the early 1580s.
