Almost all Sephardic Bnei Anusim carry surnames which are known to have been used by Sephardim during the 15th century, however, per se, almost all of these surnames are not specifically Sephardic, and are in fact mostly surnames of gentile Spanish or gentile Portuguese origin which only became common among Bnei Anusim because they deliberately adopted them during their conversions in an attempt to obscure their Jewish pedigrees. Very few Sephardic Bnei Anusim carry surnames that are specifically Sephardic in origin, or that are specifically found only among Bnei Anim.
