An article in Spanish from diariojudio.com (Mexico), dated on July 2016, about the Portuguese (and German and Ashkenazi) Jewish cemetery of Altona, Hamburg, Germany, and the Portuguese community of this town: http://diariojudio.com/opinion/el-cementerio-portugues-de-hamburgo/202469/ . I found it in the blog in Spanish of Geneanet about "Actualidades genealógicas", http://es.geneanet.org/bloges/post/2016/07/el-cementerio-portugues-hamburgo-mexico .
