Good advice, you should try it yourself, idiot.
“The DNA indicates that Christopher Columbus’s origin lay in the western Mediterranean,” Prof Lorente said. “If there weren’t Jews in Genoa in the 15th century, the likelihood that he was from there is minimal. Neither was there a big Jewish presence in the rest of the Italian peninsula, which makes things very tenuous.”
An estimated 300,000 Jews were living in Spain before the era of the “Reyes Catolicos”, during which Catholic monarchs King Ferdinand II and Queen Isabella ordered Jews and Muslims to convert to Christianity or face exile. The expulsion of Jews from Spain occurred in 1492, the same year that Columbus made his first voyage to the Americas.
Now, researchers believe Columbus either concealed his Jewish identity or converted to Catholicism to escape religious persecution. The term “Sephardic” is derived from Sepharad, a Hebrew word that refers to the Iberian peninsula, which includes modern-day Spain and Portugal.
