To whom it may interest: a Brazilian bussiness man researched 20 year the Brazilian northeast heritage and also found his jewish 20th grandmother . Seems he is already in the 4th volume of 10 and covers from the arrival of new christians in Brazil until the 19th century, focusing in the "elite" families. He uses a lot the elite word. When asked if all nordestinos ( in Brazil nordestinos are subestimated by the other regions, as Northeast is the driest and poorest region) are Jews, he answered, not only Jews, Musims, Semitic Muslims, Pagans, Native Indigenous and Black. Although he admits he has mostly Black, Christian and Native blood, he decided to convert (or better saying, to practice Judaism) because he felt, was more accordingly with his "profile". For those who are researching about Portuguese Jews, could be a good source also.http://www.culturajudaica.org.br/3153/cole%C3%A7%C3%A3-borges-da-fonseca-desvenda-genealogia-de-fam%C3%ADlias-nordestinas-de-candido-pinheiro-korenhttp://www.opovo.com.br/app/opovo/paginasazuis/2013/03/18/noticiasjornalpaginasazuis,3024621/integra-da-entrevista-de-candido-pinheiro.shtml?fb_action_ids=669193719812531&fb_action_types=og.recommends&fb_source=other_multiline&action_object_map=%5B618996711449429%5D&action_type_map=%5B%22og.recommends%22%5D&action_ref_map=%5B%5D
