Estêvão da Gama (about 1430–July 1497) was a wealthy Portuguese knight of the fifteenth century, best known as the father of explorer Vasco da Gama. Family and early life Estêvão da Gama was the eldest son (out of four) of a certain Vasco da Gama of Olivença and Dona Teresa da Silva. In the 1460s, Estêvão was a knight in the household of the royal prince Infante Ferdinand, Duke of Viseu, and, at some point, entered the military Order of Santiago. He was subsequently rewarded for his services with the position of Alcaide Mor (civil governor) of Sines, a post he held until 1478. He continued collecting taxes and dues in Sines and environs on behalf of the Order of Santiago. Order of Santiago Around 1472, the mastership of the Order of Santiago fell into the hands of Infante D. João, the royal prince and heir. Upon ascending to the throne as King John II of Portugal in 1481, the Order's fortunes - and Estêvão da Gama's - rose with him. Through the 1480s, Estêvão da Gama climbed through the ranks of the Order of Santiago, holding a variety of positions, and served John II in a position of trust. Estêvão held the comenda of Cercal and possibly Seixal on behalf of the Order. Marriage and family Estêvão da Gama married Isabel Sodré, a daughter of João Sodré (also known as João de Resende), scion of a well-connected family of English origin. She was the sister of Vicente Sodré and Brás Sodré. Estêvão da Gama and Isabel Sodré had five sons, in probable order of age, Paulo da Gama, João Sodré (who took his mother's surname), Vasco da Gama, Pedro da Gama and Aires da Gama, and one known daughter, Teresa da Gama (who became the wife of Lopo Mendes de Vasconcelos). In addition, Estêvão da Gama had an illegitimate son, confusingly also named Vasco da Gama, born of another woman while he was still single. Despite the Sodré's traditional attachment to the Order of Christ, the sons of Gama followed their father into the Order of Santiago. Service to John II After Bartolomeu Dias doubled the Cape of Good Hope in 1488, Estêvão da Gama was appointed by John II to lead the first sea expedition from Portugal to India (at least according to chroniclers Barros and Castanheda). This expedition, however, did not materialize in the lifetime of either
