I think that was discussed here at FR a few years ago. There were suddenly a lot of stories about the possible Jewish heritage of some Hispanic groups.
It is no doubt true.
My mother’s family was literally expelled from Spain, to Portugal, then got a Spanish land grant as a means of escape.
A big part of the Texas Revolution was the revolutionary promise to permit Jews to practice their religion openly — Jews not only supplied money but fought — with at least one (Antony Wolfe) dying in the Alamo, for example.
