Born in Mogadouro, Portugal, in 1539 to parents who were ostensibly Old Christians, as a youth Don Luis [de Carvajal] had no inkling of his Jewish ancestry. He was in his 20s, an important wholesale merchant who had been for a time a sea captain, when he learned of his Hebraic origins. The discovery was a devastating blow to Carvajal, a man aspiring to high Spanish and Portuguese circles. Possibly as a result of his new knowledge about his identity, Don Luis formed a close business relationship with another New Christian, the wealthy and influential Don Miguel Nunez. In 1566, the young merchant made the tie between them permanent by marrying Nunez's daughter, Dona Guiomar de Ribera. Not long after the wedding, Carvajal learned to his dismay that Dona Guiomar was devoted to the Jewish faith. Frustrated by his failure to persuade his wife to forsake Judaism and distraught over a substantial business loss, in 1568, Carvajal set out alone for New Spain. throughout his adventurous and highly remunerative early years as a conquistador, Carvajal continued his association with his father-in-law. A year after Nunez's death in 1577, Carvajal decided to settle permanently in the New World. He sailed for Spain bearing a petition to colonize a huge tract of land, much of which he or his agents had already explored and knew to be fertile and rich in resources. He presented his impressive credentials at the court of Philip II,and for six months advanced his case. During this interval, Carvajal also recruited colonists, primarily among his own relatives, but also among his wife's. Dona Guiomar, however, refused to accompany her husband to the New World.

... One of the five Rodriguez Carvajal daughters [of Don Francisco Rodriguez de Matos, purportedly a rabbi, and Dona Francisca de Carvajal, Governor Luis' sister] had promised Dona Guiomar before leaving Spain that she would beseech the governor, on his wife's behalf, to return to the laws of Moses. When Isabel revealed to her uncle that she and her family practiced Jewish rites and implored him to join them, the governor flew into a rage. He knocked the girl down and ordered her never to mention the subject again. Thereafter, the governor shunned his sister's family, except for his teenage nephew, Luis.
