For those that can read French, here is an article by Robert Ricard, published in 1939 on the Portuguese Jews in Mexico (then called Nueva Espana). It is an overview of known sources pertaining to Portuguese jews in New Spain. It lists the origins of many of these in the Portuguese towns of Alvala, Açores, Braga, Castelo Branco, Freixo de Espada, Lisbon, Mogadouro, Porto, Sarzedas, etc. as well as many from Spain (Benavente, San Martin de Trevejo, Sevilla, Andalucia, etc.)Mentions regular routes to arrive in Mexico (often via Las Palmas) often for business. The trial of Luis Carvajal el viejo shows that many Portuguese jews had moved back to Spain especially in Sevilla and from there to New Spain. On another book I am reading which has the autobiography of Luis Carvajal el Mozo we see also that from Mexico some went on to business to the Far East (Macao) in Portuguese lands, as well as regular coming and going of jews from Italy (especially poor ones looking for better opportunities).Most of these appear to have been businessmen or small merchants and pedlers, some doctors, and other like Don Luis an officer in the army. Most appear to move around very much across the country and even out of the country, sometimes for business and sometimes to escape the Inquisition. Two of the Carvajal brothers escaped to Italy and Salonica respectively where one of them became chief rabbi (under their new name Lumbroso).Hebrew does not seem to be very common among them, however Portuguese still seems to be common according to the inquisition records.There seems to have been a network of families spread from northern Mexico all the way to Peru. We find records of them in Veracruz, Taco, Pachuca, Guadalajara, Oaxaca, Mexico City and after the colonization of Reinado de Nuevo Leon by Don Luis many in the north-east in the actual states of Coahuila and Nuevo Leon. There seems to have been quite a large number of judaisers in Mexico during the colonial period. If I remember correctly the great auto da fe in 1596 had over 70 condemned to the stake.Additionally, from the processes much can be learned about the Portuguese new christians in spain and Portugal as well. In general there seems to have been two main origin regions from Portugal, one in the north in the Traz o montes region and another in Beira Baiza.
