There are many indicators that the name Spinoza may be of Jewish origin, emanating from the Jewish communities of Spain and Portugal.
When the Romans conquered the Jewish nation in 70 CE, much of the Jewish population was sent into exile throughout the Roman Empire. Many were sent to the Iberian Peninsula. The approximately 750,000 Jews living in Spain in the year 1492 were banished from the country by royal decree of Ferdinand and Isabella. The Jews of Portugal, were banished several years later. Reprieve from the banishment decrees was promised to those Jews who converted to Catholicism. Though some converted by choice, most of these New-Christian converts were called CONVERSOS or MARRANOS (a derogatory term for converts meaning pigs in Spanish), ANUSIM (meaning "coerced ones" in Hebrew) and CRYPTO-JEWS, as they secretly continued to practice the tenets of the Jewish faith.
Our research has found that the family name Spinoza is cited with respect to Jews & Crypto-Jews in at least 6 bibliographical, documentary, or electronic references:
Finding Our Fathers: A Guidebook to Jewish Genealogy, by Dan Rottenberg
In this work Dan Rottenberg shows how to do a successful search for probing the memories of living relatives, by examining marriage licenses, gravestones, ship passenger lists, naturalization records, birth and death certificates, and other public documents, and by looking for clues in family traditions and customs. Supplementing the "how to" instructions is a guide to some 8,000 Jewish family names, giving the origins of the names, sources of information about each family, and the names of related families whose histories have been recorded. Other features included a country-by-country guide to tracing Jewish ancestors abroad, a list of Jewish family history books, and a guide to researching genealogy.
A History of the Marranos, by Cecil Roth.
The expulsion of the Jews from Spain in 1492 by the infamous decree of King Ferdinand and Queen Isabella was the culmination of a series of anti-Jewish persecutions throughout the 14th and 15th centuries in which thousands of Jews were massacred. Thousands of others converted in order to escape death. After the expulsion many more joined the ranks of these "new Christians" as an alternative to exile. A large number of converts, while outwardly professing Christianity, secretly continued to practice Judaism. These Marranos, as they were popularly known, were then mercilessly persecuted by the dreaded Inquisition which through tortures of forced confessions and auto-da-fes sent thousands to the stake. Many others managed to escape to countries outside the reach of the Inquisition where they created a widespread Marrano diaspora. Thousands of Marranos have survived even into our times. This seminal work by the eminent historian traces the tribulation of these secret Judaizers as well as the fate of those who succeeded in escaping to other lands where many of them rose to prominence in various fields of endeavor.

In Sure Dwellings: A Journey From Expulsion to Assimilation, by Margot F. Salom
In 1492, the last professing Jews in Spain were driven out of their beloved Sepharad where they had formerly been accepted as an important part of a thriving, pluralistic society for seven centuries of Islamic rule. The Christian Reconquista in the last of those centuries, spelt the beginning of the end for the Jews of Spain as well as for the convivencia (cooperation) that had long existed between Jew, Muslim and Christian in what has been called the "Golden Age". Many of the expelled Spanish Jews spread out around the surrounding Muslim lands where they found some refuge. Others found a brief hiatus of safety in Portugal. Decades later many of the expelled Jews travelled to the mercantile centres of the Mediterranean, northern Europe and the New World where they participated in the burgeoning trading empires of Holland, England the Italy. It is this fascinating history that the author has attempt to trace, using her ancestors as a paradigm. Realizing that this narrative of the western Sephardim is all but forgotten with the secularisation of a resolute assimilation process, she has written a story that both describes the history of the countries of her ancestors' settlement as well as her personal search through many of the lands of their diaspora, in an attempt to establish the journey of her ancestors as they travelled from fifteenth century Spain to nineteenth century Australia. It was in Australia that this lineage finally became established in a land of "sure dwellings" and where the inevitable outcome of assimilation was the loss of an ancient faith - a loss that has created the primary impetus for the telling of this story
Noble Families Among The Sephardic Jews, by Isaac Da Costa, Bertram Brewster, and Cecil Roth.
This book provides genealogy information about many of the more famous Sephardic families of Iberia, England and Amsterdam. It documents the assimilation, name changes and conversion of many Sephardic families in Spain, England and The Netherlands. There is a large section dealing with the genealogy of the members of Capadose and Silva families in Spain and Portugal. This reference includes genealogical tables and a translation of Da Costa’s 1850 work "Israel and the Gentiles", with chapters by Bertram Brewster on the Capadose conversion to Christianity and by Cecil Roth on their Jewish history.
Around the 12th century, surnames started to become common in Iberia. In Spain, where Arab-Jewish influence was significant, these new names retained their old original structure, so that many of the Jewish surnames were of Hebrew derivation. Others were directly related to geographical locations and were acquired due to the forced wanderings caused by exile and persecution. Other family names were a result of conversion, when the family accepted the name of their Christian sponsor. In many cases, the Portuguese Jews bear surnames of pure Iberian/Christian origin. Many names have been changed in the course of migration from country to country. In yet other cases "aliases", or totally new names, were adopted due to fear of persecution by the Inquisition.
