Why would you want to know is she's Jewish or not? What difference would it make?
here are two reason
1. LAW IX of the Sieta Partidas, Laws on Jews- WHAT PENALTY A JEW DESERVES WHO HAS INTERCOURSE WITH A CHRISTIAN WOMAN
Jews who live with Christian women are guilty of great insolence and boldness, for which reason we decree that all Jews who, hereafter, may be convicted of having done such a thing shall be put to death. For if Christians who commit adultery with married women deserve death on that account, much more do Jews who have sexual intercourse with Christian women, who are spiritually the wives of Our Lord Jesus Christ because of the faith and the baptism which they receive in His name; nor do we consider it proper that a Christian woman who commits an offense of this kind shall escape without punishment. Wherefore we order that, whether she be a virgin, a married woman, a widow, or a common prostitute Who gives herself to all men, she shall suffer the same penalty which we mentioned in the last law in the Title concerning the Moors, to which a Christian woman is liable who has carnal intercourse with a Moor [i.e., confiscation of property, scourging, or death].
2. In Muslim lands, Jews are Forbidden to Marry Muslim women, as us Jews are Infidels
3. the overall reason is that i am trying to Improve Relationships with Christians and Muslims by Demonstrating Inferiority to Christians and Muslims.
