That said, Jews have always been a persecuted minority since the inquisition times in Latin America. People believed to be secret Jews and their families would be force fed pig and made to accept Jesus as the messiah or face torture, so there is a lot of social stigma about being jew in folklore and legend.
One of the most famous legends in my country is about a greedy Jew who stole Spanish crown gold, betrayed and killed the slave who helped him hide it, and then was in turn killed by the slave's son who then proceeded to use some of the gold to buy his and his mother's freedom, and hid the rest of the gold somewhere in some mountain, which he only revealed in his death bed. Mostly one of those legends for people who want to waste time searching for gold.
