Allow me to fill you in on the ‘journey’ of my own family after the expulsion; Rather than going to one of the Muslim countries in North Africa, as many others did, they chose to go to Turkey. Those that went to North Africa received a much warmer welcome, which resulted in my family eventually going on to a new situation in Holland.
They found there that in order to succeed economically they would have to assimilate with the Eastern European Jewish Community (Ashkenazim), a fate much less severe than the forced conversions to Catholicism for those who remained in Spain.
Again, after a number of years they once again moved on, this time splitting up, some going to Slovakia, the others to Hungary. Many of those in Hungary pursued their Jewish educations and became prominent members of the rabbinical community, included was Rabbi Shlomo Gantzfried, co-author of The Code of Jewish Law.
