List of 1888 Alias Names used by Sephardic Jews in Amsterdam
When Portuguese conversos fled Portugal to settle in Amsterdam they were finally able to openly return to Judaism. However, they often had relatives and family still trapped in Portugal. These family contacts along with the Amsterdam Jews ability to speak both Portuguese and Dutch were great assets in their international trade ventures but also posed risks. To avoid endangering their relatives and friends in Portugal, the Portuguese Jews used aliases in their transactions with them.
These alias names can be difficult to disentangle. Vibeke Sealtiël Olsen went through the records to determine the following:
In the first half of the 20th century Abraham de Mordechai Vaz Dias went through the notarial records kept at the Amsterdam stadarchief and used these notarial records to identify many of the aliases used. He prepared an index consisting of separate index cards (archive no. 5059, inventory nos. 267 and 268) giving the Jewish name and its corresponding aliase as well as the specific notarial record in which he identified that alias.
Vibeke Sealtiel Olsen carefully transcribed the Vaz Dias card index collection into a database which she graciously made available to SephardicGen. Many of the surnames are composite surnames (Da Costa, D'Aguire, etc.) which creates problems in searching for a specific name. It is therefore recommended that one searches this database using the "contains" search term.
We acknowledge the tremendous contributions and lifelong dedication of Mathilde Tagger, z"l who made this index available. For many years, and right until her untimely death, Mathilde Tagger was a very close friend and collaborator with Jeff Malka. Together they worked to promote Sephardic genealogy research and educate the public about its enormous potential.
In addition, we express our grateful appreciation to Dr. Jeff Malka for his monumental ongoing effort to collect and make accessible Sephardic genealogical information, and for his generosity in contributing his extraordinarily valuable collection to JewishGen.
