If your people came from Aragon, and you cannot find the name in this list, I recommend to attach a prefix and look for it in that way. In addition, the spelling of many of the stems have changed with time. There were other names which are not listed here because the author did not identify those names as Sephardic. This book contains tombstone inscriptions and dates of death from 1663-1880. Only names that appeared Sephardic are included here.
German names are due to inter marriage.
Los antepasados Judios de las familias Argentinas. This work contains many Sephardic names and family trees within its 3 volumes. Many of the individuals listed appeared before the inquistion and were secret Jews. Some later converted and intermarried. Only those names that were identified as Sephardic Jews or descendant from Sephardic Jews or in some cases, new Christians that married into Sephardic families are listed here.
