The Sephardim usually have followed the general rules for Spanish and Portuguese names. Many used to bear Portuguese and Spanish names; however, it is noteworthy that a large number of Sephardic names are of Hebrew and Arabic roots and are totally absent in Iberian patronyms and are therefore often seen as typically Jewish. Many of the names are associated with non-Jewish (Christian) families and individuals and are by no means exclusive to Jews. After 1492, many marranos changed their names to hide their Jewish origins and avoid persecution, adopting professions and even translating such patronyms to local languages like Arabic and even German. It was common to choose the name of the Parish Church where they have been baptized into the Christian faith, such as Santa Cruz or the common name of the word "Messiah" (Savior/Salvador) or adopted the name of their Christian godparents. Dr. Mark Hilton's research demonstrated in IPS DNA testing that the last name of Marranos linked with the location of the local parish was correlated 89.3%
