I cannot find a link to Brazil. However, I can tell you that my father-in-law was born, Michele Anton Maraccini. He was born in Oakland to parents from Lucca. He went back to Lucca and returned through Ellis Island where they added the second "r"...his thought, was if that is how they do it in America, it must be right. His siblings did not do that. Hope this helps. I do know of a big firm in SF, Marraccini/Patterson not related to Michele, but it does seem to have the double "r".
