The family De Morais were from the first settlers by 1590 in the Nuevo Reino de Vizacaya y Nuevo Reino de León in New Spain, now known as Coahuila, Durango and Nuevo León, Mexican States. Manuel Abraham de Morais was known as a distinguished Rabbi and physician. He left descendants in these regions, before he left to travel to Venice Italy where he died. Their descendants have changed to Morales surname (more Spanish). In Saltillo and Torreón Coahuila, as well in Monterey Nuevo León Mexico, their descendants still conserve this surname. Those identified in these lineage are intellectuals, writers, musicians, physicians and scientists. They have contributed to maintain a kind of Jewish primacy for knowledge, but unfortunately they have lost their cultural and religious links to Judaism. Personally I'm working to have a more clear perspective of this lineage. Any information about Manuel Abraham de Morais' family will be very useful, specially if these data are from Portugal, Spain or Italy, before 1590.
