LuxCitizenship visited Curitiba, Paraná, Brazil, Brazil’s 8th largest city and undoubtedly the second most important concentration of Luxembourg Dual Citizens in Brazil. During the visit, we got to meet the Honorary Consul to Paraná Andrea VIANNA and visit the location of her office, the Centre Europeu, a language and career training school in the city. Additionally, during our visit, we were able to attend the launch of a book about Nicolau BLEY, a Luxembourger who immigrated to this Brazilian state in 1827 and is said to have 15,000 direct descendents. This is the second edition of an extensive genealogical research program that started in the 1960s. Thousands of Nicolau BLEY’s descendents are said to have Luxembourg Dual Citizenship.
