Re: Jewish gauchos Argentina #latinamerica
You could write to Estela Rapoport at consultas.agja@.... AGJA is the Argentinean Genealogic Jewish association.
The JCA files and the 1912 census of the colonies may shed some light. Estela has access to them.
The "sepelios" files from the AMIA are difficult to search because they do not have SOUNDEX.
But the same information is in JOWBR JewishGen database with SOUNDEX. I could not find my great-grandfather in the AMIA files, but I did find him in JOWBR with the command "sounds like".
