Online searching is available for Baron Hirsch related genealogical records available through the Center for Jewish History in New York. See the video at this Facebook link below for instructions. Some complete records are online, and when only a reference to a record is online you can request the full document from the Center.
In addition, the genealogical and historical archives described below (alphabetized by city) contain reports and correspondence relating to Baron Hirsch-funded Jewish farming projects and individual immigrants who received aid from the Baron Hirsch charitable organizations. These archives are scattered around the world. Some of the holdings have been uploaded digitally – see the links below – but most are only available on-site.
For texts in French, Spanish and Portuguese I suggest copy-pasting into google translate. It really works.
I also translated to English the first work to feature the Jewish community in Brazil as subject matter. It is On a Clear April Morning, an autobiographical novel by Marcos Iolovitch. In this novel, he relates growing up as a Ukrainian immigrant to the Quatro Irmãos farming colony in southern Brazil. Quatro Irmãos was one of many colonies supported by Baron Hirsch’s donations.
I hope you will send us your ideas to make this a richer online depository.
